What is High Intensity Focused Ultrasound?
High Intensity Focused Ultrasound (HIFU) under MRI guidance is an innovative non-invasive technology for treating Uterine fibroids. It uses high-intensity ultrasound waves that are focused on a small area to produce heat energy. This results in thermal ablation of the fibroid tissue. The MRI is used to localize the area for ablation as well as monitor the temperature, thus ensuring that it is done accurately.
HIFU is a new technique and is used in the therapeutic management of treating fibroids. Its main aim is to reduce the symptoms related to fibroids mainly pain, excessive bleeding and urinary urgency / pressure symptoms. Only the fibroids are treated, the uterus is preserved.
As preparation for the procedure, the patient will need to fast for 4 to 6 hours before the procedure and the pelvic area will need to be shaved.
The procedure takes about 3 hours.
- A catheter is placed in the bladder
- The patient has to lie on her stomach in the MRI scanner with her head out
- A button is given to the patient to stop the ultrasound beam whenever she feels uncomfortable
- The team consisting of the doctor and nurse will be in constant touch with the patient
