  • Outlook 2013: Advances in Brain Indications Serve as a Bellwether for Entire Focused Ultrasound Community

    The pipeline for clinical studies using focused ultrasound to treat brain conditions is more robust than ever. Neal Kassell, MD, chairman of the Focused Ultrasound Foundation says this is key to his positive 2013 outlook for the field of focused ultrasound.

    Asserting that the brain is the most complex and most difficult organ to treat, he says, “Developing safe and effective treatments for brain conditions is the best way to validate focused ultrasound technology and to accelerate its application throughout the body. It doesn’t take an enormous leap of faith to understand that if you can treat something deep in the brain with extreme precision and accuracy—safely and effectively—in a patient who’s wide awake, with no anesthesia, that you can use focused ultrasound in other areas of the body.”

  • Interview with 2012 Young Investigator, Jonathan Kopechek, PhD

    KopechekWe followed up with Jonathan Kopechek, PhD, who attended the symposium for the first time in 2012 through the program. Kopechek presented his research titled, “Enhanced MR-guided HIFU Ablation of Rabbit VX2 Tumors In Vivo using Phase-Shift Nanoemulsions.”

    Q: It’s been just over a year since the symposium. What are you doing now? 

    A. I am currently a postdoctoral fellow at the University of Pittsburgh Medical Center. My research involves ultrasound and microbubble-targeted delivery of therapeutics agents for treatment of cancer and cardiovascular conditions. Although my current position is not specifically in FUS, it is in a closely related research area.

    Q. Describe your experience at the 2012 Symposium.
    A. I benefited from the excellent and informative presentations at the Symposium, which expanded my knowledge on FUS research and applications. However, the most important benefit was the opportunity to meet in person with many outstanding researchers in the FUS field. It was an excellent networking experience, and many connections were formed that will likely continue for the duration of my career.

    Q: How did being a Young Investigator award recipient impact your experience?
    A: Presenting a poster as a Young Investigator awardee was very helpful to the networking process. Furthermore, without the Young Investigator award, I would only have been able to attend one day and would have missed out on meeting many FUS researchers at the Symposium. As a result of the Young Investigator award, however, I was able to attend the entire Symposium.

    Q. Would you recommend others to apply for the Young Investigator award? 
    A. I would absolutely recommend applying for the Young Investigator award. The opportunity to attend the entire Symposium was important. In addition, the opportunity to present as a Young Investigator awardee at the poster session was a very beneficial experience.

    Q: Do you have any tips for researchers interested in applying for a Young Investigator award in 2014? 
    A: I would recommend focusing on a research topic that will garner as much interest as possible in the FUS research community.

    Q: Do you plan to attend the 2014 meeting? 
    A: I hope to return. It will depend on whether I can secure funding.

  • Konofagou Receives Foundation Research Award to Study FUS-mediated Treatment for Neurological and Neurodegenerative Diseases

    Elisa Konofagou, PhD envisions a day when effective treatments and cures are available for neurodegenerative diseases such as Alzheimer's, Parkinson's, multiple sclerosis and amythrophic lateral sclerosis (ALS). Toward that end, she has been researching noninvasive ways to temporarily open the protective blood-brain barrier that now limits the delivery of most systemically-administered treatments for those diseases. 

    The Focused Ultrasound Foundation is supporting her work via a $100,000 research award that will enable Konofagou, an associate professor of Biomedical Engineering and Radiology at Columbia University in New York, to conduct a study that will explore the use of focused ultrasound in opening the blood-brain barrier opening to facilitate drug delivery in neurological and neurodegenerative diseases.

    “The underlying hypothesis of this study is that delivery of therapeutic molecules is safe and effective through the blood-brain barrier using focused ultrasound,” Konofagou explains. “Our preliminary results have shown that the FUS technique can induce blood-brain barrier opening entirely noninvasively, selectively and be monitored with MRI at sub-millimeter resolution in vivo.”  During the study, Konofagou will test and demonstrate delivery of neurotrophic factors to the hippocampus and putamen regions of the brain and assess the safety of the focused ultrasound method.

  • Study Advances Understanding of Focal Drug Delivery to the Brain

    In a preclinical study published in the Journal of Controlled Release, Harvard Medical School researchers investigated the kinetics of blood-brain barrier permeability and drug delivery following single and double focused ultrasound sonications. They found that delivery of the chemotherapy agent, doxorubicin, was significantly greater when one focused ultrasound sonication was used and 1.5-fold higher when a second sonication was administered ten minutes later. Study data suggests that MRI contrast agent Gd-DTPA may be useful as a surrogate tracer in estimating drug delivery to the brain following focused ultrasound-induced blood-brain barrier disruption.

  • Breast System Project Leads to International Collaborations on MR Thermometry for Liver and Brain Indications

    As Dennis Parker, PhD and his colleagues at the University of Utah continue to refine and advance their new HIFU system for breast tumors, they have also joined forces with Swiss and French researchers to solve the technical problems of measuring temperature changes during focused ultrasound treatments.

    In designing their system, the Utah team has come up against significant technical challenges. For example, they had to determine how to measure temperature changes in fatty tissues, adjust for motion-related errors and cover larger volumes at acceptable spatial and temporal resolution. Their quest for solutions led to a collaboration with University of Geneva researchers who are addressing similar problems in developing a HIFU system for liver tumors. The Foundation supported this collaboration through a $100,000 Research Award for a project entitled, “Robust MR thermometry for MRgHIFU in breast and liver.” (Click here to read a previous newsletter report about that project.)

  • Utah Researchers Developing Focused Ultrasound System to Treat Breast Tumors

    Known as a luminary in medical imaging, Dennis L. Parker, PhD is currently devoting much of his time to focused ultrasound. Parker, a professor of Radiology at the University of Utah and Director of the Utah Center for Advanced Imaging Research (UCAIR), is co-leading the development of a high intensity focused ultrasound (HIFU) system for breast tumors.

    The project’s origins trace back to 2003 when Utah purchased its first MRI scanner from Siemens. “Because the Siemens MRI scanner was very open as far as its software architecture, our students were able to very, very quickly establish a closed feedback loop feeding images out of the scanner into the ultrasound controlling computer that we had at the time,” Parker recalls. This led to the development of a closed-loop MRI guided focused ultrasound system.

    “When Siemens came to visit in 2004, they actually decided to pick up that project and provided some funding,” he notes. At the time, Image Guided Therapy (IGT), a French medical device maker, had just designed a phased-array focused ultrasound transducer.

    “Siemens purchased that device and placed it in Utah as IGT’s first large animal focused ultrasound system,” Parker adds. “Ever since that time, we’ve been working with them.”

    By 2006, Parker and his collaborators decided that the best candidate site for their system would be the breast, and they applied for funding from the National Institutes of Health to develop a prototype. “It was an academic/industrial partnership,” he says. “We were very lucky. We were funded on the first submittal, which is very rare, but we were delighted.”

    His collaborators on the project represent numerous disciplines and several departments at the University of Utah. In addition to Parker, the team includes Robert B. Roemer, PhD from Mechanical Engineering; Douglas Christensen, PhD from Bioengineering; Allison Payne, PhD, Rock Hadley, PhD, Emilee Minalga, PhD, Robb Merrill, PhD and Nick Todd, PhD from UCAIR; Leigh Neumayer, MD from Surgery/Oncology; and many students.

    New breast system has unique features  

    Utah’s system, says Parker, “has a lot of capabilities not found in other breast HIFU systems.” Unique features include the placement of the focused ultrasound transducer. Mounted on flexible bellows made of PlastiDip (an idustrial grade fabrication material), the transducer can be moved into and out of the treatment cylinder as needed. Also unique is that the transducer shoots laterally. The system has a small water box in which the breast is suspended. That box has an array of radio frequency coils around it. According to Parker, this provides “image quality from the MR side [that] is actually very, very good.”

    The system’s other major components are an MR-compatible ultrasound generator made by IGT and a Siemens MRI scanner.

    Now in prototype form, the system has been tested on phantoms and samples. “From the standpoint of something that could ultimately be used to treat breast cancer, I think this is an excellent potential device,” Parker says. “The advantage of HIFU for breast cancer is that it’s totally noninvasive. It has the opportunity eventually to totally eradicate the disease without any surgical intervention at all.”

    A patent application has been filed for the system and further improvements are planned. “There are many problems that still need to be solved,” he notes. “Measuring temperature in fat, which is a major component of breast tissue, has not been solved yet by others. We’ve got a good technique that is starting to work and we’re optimistic that with all these little pieces it’ll be a good system.”

    The team, says Parker, will seek funding to develop modifications that improve image quality and enable the system to treat more aspects of breast disease. “Our new design should be able to treat much more of the disease, including many metastatic lesions,” he notes.

  • Working on Focused Ultrasound Projects That Will Soon Affect Patients is “Very Inspirational”

    Researcher interview: Urvi Vyas, PhD, Stanford University

    A highlight of the FUS Foundation’s 2010 International Symposium on MR-guided Focused Ultrasound was the presence of our Young Investigators, ten early-career scientists selected to present their work during oral or poster sessions. The spirit and enthusiasm of these individuals provided a special spark that energized the entire symposium.

    During a recent interview, one of those Young Investigators – Urvi Vyas, PhD – provided an update on her focused ultrasound activities. The excitement and positive expectancy with which she spoke were truly inspirational. 

    Vyas, who is now a post-doctoral fellow at Stanford University, earned her PhD in bioengineering at the University of Utah. Professionally, her main interests are ultrasound beam propagation and MR-guided focused ultrasound surgery. Like many of the unsung heroes in the field of focused ultrasound, she is working behind the scenes to address technical issues and challenges that will make new patient treatments possible.  

    What is ultrasound beam propagation? Click here to find out.

    After completing her undergraduate degree in bioengineering at Shree Govindram Institute of Technology and Science in India, Vyas joined Utah’s bioengineering program where she helped develop an NIH-funded focused ultrasound system for breast cancer. That project enabled her to learn from three individuals she describes as mentors: ultrasound expert Douglas Christensen, PhD,MR leader Dennis Parker, PhD, and biothermal specialist Robert Roemer, PhD.

    “I think this is an exciting field because you need so many people to come together to make a system work. You need temperature measurements. You need the ultrasound to work. You need to control the ultrasound. Not only that, you need to control the heating and so you need somebody that knows the bioheat transfer equation,” Vyas observes.

    Focused ultrasound system for the breast

    In creating a focused ultrasound system for the breast, the Utah team had to break new ground in a number of areas: measuring temperature in the breast, planning patient treatments and designing a transducer. “Where I came in was the ultrasound part of all of this,” says Vyas.

    She worked on developing fast simulations for ultrasound beam propagation. “We went from a time scale of a couple of hours to simulate one beam propagation pattern to a few seconds. This was on a grad student laptop, so this was really exciting. Once we had that working, we could then design patient-specific treatment plans. We’d take an MR image of the patient and then design a treatment plan that would fit this particular patient,” she explains.

    After helping to reduce treatment planning time, Vyas got involved in designing an ultrasound transducer for the breast. “We designed various configurations and figured out that the side-shooting transducer would work best for the breast,” she says.

    Inverse problem-solving

    Her next task was using fast beam propagation simulation to solve an inverse problem. “In the forward problem, I can simulate where the beam is going to be. I can also do the inverse problem. I can see the temperature and figure out what the tissue properties for this particular person are because it’s very hard to measure acoustic properties of a human being without cutting the human being open,” she says.

    Solving the inverse problem lead to a first-time in vivo study in which the Utah team demonstrated that the acoustic properties of muscle could be measured noninvasively with focused ultrasound. This work qualified Vyas for the FUS Foundation’s Young Investigator Award and for an award from the Society for Thermal Medicine.

    At Stanford, Vyas is working with Kim Butts Pauly, PhD, a leader in MR thermometry. Her energies are now being directed to correcting trans-cranial phase aberration. “When you put the ultrasound beam through the skull, there are a lot of aberrations because of the skull having different thicknesses,” Vyas explains. “The plan is to use the acoustic radiation force imaging and figure out how to better correct these aberrations in the brain.”

    Although the clinical applications of this approach have not yet been determined, Vyas hopes it will be widely useful. “I think what we want to do is give the field a very efficient, fast way of doing phase aberration correction and just share it with everybody,” she says.

    Vyas is inspired by the thought of patients benefitting from her work. “When you’re in a lab typing code on a computer, you don’t realize what it may lead to,” she says. Attending the FUS Foundation’s recent Brain Workshop gave her a glimpse of the impact her work could have on patients. There, she heard doctors talking about treatment envelopes based on simulations she helped develop. “These treatments are going to be in clinics really soon, and it’s very exciting,” she exclaims.

  • Final Patient Treated in FUS Foundation-funded Essential Tremor Study

    The last of 15 patients was treated in mid-December in the world’s first clinical trial using MR-guided focused ultrasound as a therapy for essential tremor. The single-site pilot study, which has been funded by the FUS Foundation, began in February 2011 at the University of Virginia with neurosurgeon W. Jeffrey Elias, MD serving as principal investigator. 

    All study participants are being followed for three-months, and final clinical trial data is expected to be available in March 2012. Elias will present that data at the 2012 American Association of Neurosurgeons meeting, scheduled for April 14-19. 

    Preliminary study data, which was presented by Elias at the 2011 Congress of Neurological Surgeons meeting in October, was highly promising. The study’s first 10 patients experienced a 78 percent improvement in contralateral tremor scores in their dominant hand, as assessed with the Clinical Rating Scale for Tremor (CRST). Patients’ functional activities scores improved by 92 percent, as measured in the ‘Disability’ subsection of the CRST. Elias said that outcomes and complications were comparable to other procedures for tremor, including stereotactic thalamotomy and deep brain stimulation.

  • MRgFUS Could Be a Viable Option for Facet Joint Back Pain

    According to a story recently published by the UK-based Daily Mail Online, researchers have successfully treated 15 patients using MRgFUS for facet joint-related back pain in a clinical trial at St. Mary’s Hospital in London.

    During the treatment, the patient lies in an MRI scanner while doctors deliver beams of ultrasound to the nerves of the facet joints, using images from the scanner to position the beams. The low-energy sound waves do not damage healthy tissue but are angled by the physicians so that they cross over each other at the position of the facet joints, numbing the nerves.

    Researchers reported that the focused ultrasound treatment resulted in a 62 percent decrease in pain and a 55 percent decrease in disability.

    MRgFUS shows promise as a viable option for facet joint back pain, particularly in cases that may be resistant to other treatments.

    “The follow-up data that we have collected is very promising, with up to 60 percent reduction in pain and a similar level of reduction in the level of disability, as measured by NRS and Oswestry Disability Index scores,” Gedroyc says.

    The start date of the clinical trial will be determined following the approval of the study protocol by the ethics committee at St. Mary’s Hospital.

    Gedroyc says, “It is difficult to estimate how many people suffer from facet joint disease because chronic back pain is large mish-mash of many pathologies. One of the big problems is that people are often treated for facet disease when they may have other problems of the back.” 

    For this reason, the studies at St. Mary’s only recruit patients who have demonstrated a definite response to a previous facet intervention. “By a ‘facet intervention’ I mean something like a local anesthetic or steroid injection close to the facet join, or a joint injection of steroids, or possibly a radiofrequency ablation of the nerves around there,” Gedroyc explains. Radiofrequency ablation, he says, is the current gold standard for facet joint treatment.

    The new technique uses MR-guided focused ultrasound to destroy nerve structures in degenerative facet joints. “We simply heat up the facet joints with focused ultrasound in a noninvasive manner so that we destroy the nerve bundles along the posterior aspect of the facet joint,” Gedroyc says. “We believe these nerve bundles are instrumental in causing pain from facet joint disease.”

    If clinical trials are successful, he adds, “It means that we will have created a method of treating facet joints with an entirely noninvasive modality. No radiation will be involved. Just an MR scan using focused ultrasound. So, the patient would come in, lie down on the table, we would treat probably three facet joints on each side, and they will walk out. And we anticipate that we could do this in about half an hour or so. If it is long-lasting, then we have a huge potential for improving the way patients are treated, requiring no more injections.”

    Key developments and information related to the randomized clinical trial at St. Mary’s will be covered in future issues of this newsletter.

  • ISTU Meeting Highlight: Ultrasound-based Neurostimulation Presentation

    ISTU meeting highlight: ultrasound-based neurostimulation presentation

    Matt Eames, Ph.D., Senior Project Engineer for the FUS Foundation’s Brain Program, filed this blog following the recent ISTU 2011 meeting, held April 11-13 in New York City:

    Among many interesting invited talks at this year’s ISTU in Manhattan was that of William Tyler, Assistant Professor of Biomedical Engineering and Science at Virginia Tech (, on the topic of ultrasound-based neurostimulation.  Dr. Tyler, a prominent member of the FUS Foundation’s Collaborative Research Network, presented a fast-paced talk explaining the mechanics of neurotransmitters and synaptic junctions, and how this knowledge led him to explore the use of ultrasound – as opposed to transcranial magnetic stimulation (TMS) or transcranial direct current stimulation (tDCS) – as a non-invasive means to disrupt or alter neuronal function.  While still in the research realm, it is hoped that the regulatory approval environment for clinical procedures based on this technology will be relatively straightforward due to the extremely

  • World's First Essential Tremor Patient Treated with MR-guided Focused Ultrasound - Patient Interview with Billy Williams



    The last ten years have been challenging for Billy R. Williams of Fort Valley, Virginia. The former Pentagon employee, who survived the 9/11 terrorist attack, has suffered from essential tremor, a progressive and debilitating neurological disorder.

    Medications controlled his tremor for a while, but eventually the shaking became so severe that Williams found it impossible to do anything with his dominant right hand. He was unable to button his shirt, eat without spilling or fill in a crossword puzzle. An avid golfer, he even needed help teeing up his ball. Referred to the University of Virginia for evaluation, he learned about various treatment options and ultimately agreed to participate in a new clinical trial. Funded by the FUS Foundation, the study is assessing the safety and initial efficacy of noninvasive MR-guided focused ultrasound as a treatment for essential tremor.

    On February 25, 2011, Williams became the first essential tremor patient in the world to receive MR-guided focused ultrasound therapy, and the results were dramatically positive.

  • Researcher Interview: Nathan McDannold, Ph.D., Brigham and Women’s Hospital, Boston, USA Research Interest: Enabling Drug Delivery to the Brain

    As a researcher, Nathan McDannold, Ph.D. is on a quest to improve the delivery of drugs to the brain. “Most drugs don’t actually get into the brain when you inject them into the body or if a person takes a pill because of the blood-brain barrier,” he explains. “It places a big limitation on what drugs you can use.”

    In preclinical studies a decade ago, McDannold and his colleagues made an important discovery: the blood-brain barrier (BBB) could be temporarily disrupted without causing damage. Doing so involved the use of pulsed, low power ultrasound combined with small microbubbles filled with a contrast agent for ultrasound imaging.

    Since then, McDannold’s goal has been to translate this discovery into safe and effective patient therapies that not only treat brain disorders but also precisely target where drugs are delivered. He is now investigating the use of MR-guided focused ultrasound in opening the BBB. The approach has so far proven successful and safe in large animal models.

    Encouraging research has also been performed by Eun-Joo Park, Ph.D., a research fellow on McDannold’s team. “She looked at treating breast cancer metastases in the brain using Herceptin,” McDannold explains. “A lot of patients get breast cancer, and they respond well to drugs. But when it metastasizes to the brain, they don’t respond to the drugs very well anymore. So, we hope that by disrupting the blood-brain barrier in the tumor and around it, we can get drugs into the brain and help these patients.”

    McDannold envisions many brain disorders benefitting from focal drug delivery. “There are some results in animals showing that we can actually clear out some of the plaques that are formed in Alzheimer’s. There are other applications for diseases like Parkinson’s or multiple sclerosis, potentially,” he observes. “This stuff is really wide open for us to look at. We’re just sort of scratching the surface and developing the technology that will enable a lot of other research.”

  • Recent Publication: Focal Drug Delivery Proof of Concept Study

    A recent publication by Holger Grüll, Ph.D. and his colleagues has been hailed as an important development in the SonoDrugs project. Launched in November 2008, SonoDrugs is a multinational, 15-partner research consortium backed by the European Union’s Seventh Framework Programme (FP7) and aimed at holding the line on healthcare expenditures while providing access to state-of-the-art medical care. The consortium is developing new therapeutic options for cancer and cardiovascular disease that offer greater efficacy, reduced side effects, fewer burdens on the patient and faster recovery times than existing treatments.

    SonoDrugs researchers are combining MR imaging, ultrasound and liposome technologies to develop delivery methods that release drugs locally at the diseased tissue site. These methods are designed to be triggered by focused ultrasound induced pressure or temperature stimuli.

    The paper by Grüll and his colleagues, “Magnetic resonance imaging of high intensity focused ultrasound mediated drug delivery from temperature-sensitive liposomes: An in vivo proof-of-concept study,” was published in the February 2011 Journal of Controlled Release. Its key findings were:  1) local delivery improves drug uptake in tumors and 2) drug uptake can be visualized and measured by MR imaging in real time.

    The preclinical research used temperature sensitive liposomes and a combination of MR imaging and ultrasound technologies for local delivery of chemotherapy. The liposomes contained doxorubicin and a clinically used contrast agent based on gadolinium. Because it could be tracked by MR imaging, the contrast agent enabled researchers to visualize and monitor drug uptake in the tumor and surrounding tissue in real time.

    Real time capability is expected to be a significant advancement when this new method enters clinical use. It will enable physicians to determine if a tumor is absorbing sufficient chemotherapy or if additional or alternative treatment is needed. Insufficient drug absorption can occur in tumors with poor blood supply, which cannot be detected during existing cancer treatments.

    Although encouraged by the findings, Grüll says, “I would like to be yet cautious about the translational value of our approach. We are dealing with a formulation that contains a gadolinium-based contrast agent and doxorubicin, so we have to first make sure about toxicity and toxicity profiles. Many things have to be sorted out and much more work has to be done in the preclinical space before we can bring this approach further in the direction of the clinic.”

    He adds, “Preclinical studies are now determining if improved drug delivery enhances survival rates. I hope that within the next year we will have that data.”

    Ultimately, Grüll believes that temperature induced drug delivery will become an important special application for cases that cannot be address with conventional approaches. “I think the technique has strong value for metastatic tumors that are localized and confined. For example, it may be a good option for pancreatic cancer or liver cancer patients who have a localized tumor that cannot be treated in any other way.”
