Do patients experience pain during the intervention?

The most frequent side effects of MR-HIFU treatment include slight discomfort and pain, but the level of severity of these effects is usually low. One of the most frequently reported complaints among patients is the discomfort caused by lying on their stomach on the scanner for a prolonged period. The HIFU beam can also cause pain during the treatment — particularly if therapy cells are positioned close to the fibroid capsule.


Preparing patients for MR-HIFU

A day before treatment, the patient is advised to shave/depilate the hair in the pelvic area. This should be done 1 to 3 days before the intervention. The patient must not use any skin creams after the area has been shaved/depilated. Patients are also asked to fast for 12 hours prior to the treatment.


Fibroids treated with MR-HIFU

Virtually all types of fibroid can be treated, provided they can be reached by the HIFU beam without the beam's path being blocked by the intestine. Subserosal, intramural and submucosal fibroids can be subjected to routine treatment. Subserosal fibroids can be treated up to a margin of 1.5 cm from the serosal surface. In women who do not wish to have children, submucosal fibroids can be treated up to the endometrial surface. Pedunculated fibroids with thin stalks must not be treated.



Magnetic resonance imaging-guided high intensity focused ultrasound (MR-HIFU) is a non-invasive therapy that uses focused ultrasonic waves to heat tissue in the body and to cause this tissue to coagulate, without damaging the surrounding tissue. During HIFU treatment, the ultrasonic beam penetrates the skin and soft tissue and causes localized high temperatures in the target area only, while ensuring the skin and the surrounding tissue remain intact. The target area for ablation is called the therapy cell.


Uterine Fibroids

What are fibroids?

Fibroids are benign (non-cancerous) growths found in the uterus. Many women are affected without being aware of it as they may not experience any symptoms. If fibroids occur at an awkward position in the uterine cavity or are quite large, they may however cause symptoms and should then be treated.  

Fibroids are growths occurring in the muscles of the uterus. They are made up of smooth muscle fiber and connective tissue.
