Interventional radiologists gathered this month in Vancouver for the Society of Interventional Radiology 2016 Annual Meeting.
Pejman Ghanouni, MD, PhD, participated in an Expert Panel on the Future of Ablation Techniques and Technology. His presentation, entitled “Magnetic Resonance Guided Focused Ultrasound: Transcranial Applications,” was discussed with other emerging interventional technologies.
In their abstract entitled “Treatment of Osteoid Osteoma Using MR Guided High Intensity Focused Ultrasound: Preliminary Results after Four Patients,” the Stanford Group presented their initial successful experience using focused ultrasound to treat osteoid osteomas in four patients, with 6 months follow-up. Because of its non-invasive, radiation-free, and safe profile, the team now offers MR-guided focused ultrasound treatment as a routine clinical option for patients with osteoid osteomas.
Elizabeth David’s group from Sunnybrook Health Sciences Centre presented an abstract on “Optimization of the non-perfusion zone in focused ultrasound ablation of fibroids: the ‘vascular’ effect,” concluding that inferiorly placed sonication cells may help achieve complete ablation of target lesions by transferring heat to uterine arterial branches, producing a delayed vascular effect, thereby increasing the nonperfused volume.
