MRgFUS Magnetic Resonance Imaging -Guided Focused Ultrasound Surgery

· Uncategorized

High intensity ultrasound is focussed on to the tissues affected and MRI allows the tissue targeting and real-time temperature feedback.It is controlled and localized without damaging the adjacent tissues.

The beam travels through a gel pad and water bath , which creates acoustic coupling.
Advantages are–
It is a non invasive technique.
Exact tissue targeting is done.
Beam path can be visualized using MRI
Real time thermometry.
Post treatment contrast imaging for evaluation of the outcome.
Success rate :80%
Side effects :Buttock pain and leg numbness in some women which resolves spontaneously.It is due to sonification of the sciatic nerve.
