Sonalleve MR-HIFU
Encyclopedia
Sonalleve MR-HIFU is a medical system developed by Philips
Healthcare for the treatment of uterine fibroids
without surgery . The system is using non-invasive High Intensity Focused Ultrasound (HIFU) technology guided by Magnetic Resonance (MR). Hence the acronym MR-HIFU. The procedure involves volumetric heating with real-time feedback.
The method is quicker than other procedure such as hysterectomy
, myomectomy
, or uterine artery embolization
and can be done on an out-patient basis.
The procedure is performed in three stages:
Planning stage: Three dimensional MR imaging is used to plan and simulate the procedure.
Non-invasive treatment stage: high-intensity ultrasound focused onto the fibroid elevates its temperature and causes the tissue to coagulate, the process being monitored and controlled by MR imaging and feedback.
Therapy verification stage: contrast enhanced MR imaging is used to assess the procedure
