Magnetic Resonance guided Focused Ultrasound
MRgFUS, short for Magnetic Resonance guided Focused Ultrasound, uses magnetic resonance imaging (MRI) to identify tumors or fibroids in the body, and focused high-intensity ultrasound to destroy them. During the procedure delivery of Focused Ultrasound energy is guided and controlled using MR thermal imaging. MR imaging provides a three-dimensional view of the target tissue, allowing for precise focusing of ultrasound energy. The MR imaging provides quantitative, real-time, thermal images of the treated area. This allows the physician to ensure that the temperature generated during each cycle of ultrasound energy is sufficient to cause thermal ablation within the desired tissue and if not, to adapt the parameters to ensure effective treatment.
Uses
MRgFUS is currently used in the US, Israel, Europe and Asia to treat uterine fibroids. Current clinical trials are underway, examining the possible use of the technique in the treatment of cancers of the brain, breast, liver and bone.
