Delivering Focused Ultrasound to Intervertebral Discs Using Time-Reversal

Research Roundup 2019 smWhile seeking to treat low back pain caused by degenerative intervertebral discs (IVDs), researchers at the University of Oxford conducted a simulation-based feasibility study using high intensity focused ultrasound (HIFU) to mechanically fractionate degenerating tissue in the IVD, remove it with a fine needle, and replace it with an injectable biomaterial that restores normal physiologic function. Could HIFU safely cross the spinal cord to fractionate the damaged IVDs? If so, using what parameters? See Ultrasound in Medicine and Biology >


Magnetic-resonance-guided Focused Ultrasound Treatment of Non-spinal Osteoid Osteoma in Children: Multicentre Experience

Could focused ultrasound replace radiofrequency ablation as the first-line treatment for children with osteoid osteoma? Researchers from three university hospitals combined data from 33 procedures in children with a mean age of 13.8 years and then followed the patients for two years. If focused ultrasound is safe and effective for these patients, what is the next step? See Pediatric Radiology >
