MR-HIFU Treatment of Painful Osteoid Osteoma

"MR-HIFU is an innovative technology that allows for non-invasive thermal ablation of tissues and tumors by integrating an external high intensity focused ultrasound (HIFU) transducer with a conventional MRI scanner.~The focused ultrasound transducer is placed outside of the body and generates and focuses acoustic energy to heat tumors or other pre-defined focal regions of tissues inside the body. Because the acoustic energy is precisely focused over tiny areas of tissue, potential thermal injury to surrounding tissues is minimal. Cell death inside the selected treatment area occurs via coagulative necrosis while avoiding injury to intervening and adjacent tissues."
