Brief Summary
So-called type 1 and 2 uterine fibroids are well treatable with Magnetic Resonance guided High Intensity Focused Ultrasound (MR-HIFU). The other type, type 3 fibroids, however, are known for their high perfusion and poor treatment outcome after MR-HIFU. This study proposes a new strategy to treat type 3 fibroids with MR-HIFU. Very precise, small, high-power sonications (heating points) will be used to occlude (part of) the feeding vessels of the fibroid. This deminishes the negative effect of the high perfusion and is hypothesized to transform a type 3 fibroid into a type 2 or possibly even a type 1 fibroid. Consequently, the bulk volume of the fibroid can be treated using the standard approach.

Outcome Measures
Primary Outcomes (2)
Time to peak
The main endpoint of this feasibility study is the manipulation of perfusion in the type 3 uterine fibroid. The perfusion will be assessed by comparing the results of dynamic contrast-enhanced MRI (DCE-MRI) before and after treatment and after three months, i.e. the time to peak values. Data will be analyzed using Philips IntelliSpace Portal.
three months
Regional Blood volume
The main endpoint of this feasibility study is the manipulation of perfusion in the type 3 uterine fibroid and the possibly related adverse events. The perfusion will be assessed by comparing the results of dynamic contrast-enhanced MRI (DCE-MRI) before and after treatment and after three months, i.e. regional blood volumes (area under the curve). Data will be analyzed using Philips IntelliSpace Portal.
