About this trial

This is an interventional diagnostic trial for Leiomyomas focused on measuring Leiomyoma, Diffusion weighted MRI, Perfusion MRI, Uterine artery embolization, Volumetric Response, Women with symptomatic leiomyomas

Eligibility Criteria

undefined - undefined (Child, Adult, Older Adult)FemaleDoes not accept healthy volunteers

Inclusion Criteria:

  • women with symptomatic leiomyomas

Exclusion Criteria:

  • women with known contra-indications for MRI (cardiac pacemaker, cochlear implants, claustrophobic patients)
  • women with contra-indications to gadolinium-based contrast agents (including patients with a known restricted renal function; GFR < 30 mL/min)

Sites / Locations

  • Radiology Department

Outcomes

Primary Outcome Measures

Diffusion -and perfusion weighted MRI as a predictor for volumetric response of leiomyomas after uterine artery embolization
Patients will be scanned before (baseline) and after (the day of embolization, 3 days and 3 months after embolization). Measurements of signal intensity (SI) will be performed placing ROIs in the central portion of the lesion avoiding areas of artifact. Apparent diffusion coefficients (ADCs) will be calculated at different time points (before and after embolization). Signal intensity measurements on the dynamic contrast enhanced imaging data sets will be performed.

5. Study Description

Brief Summary
It is known that volumetric response of leiomyomas following uterine artery embolization correlates well with patients clinical outcome. The aim of this study is to assess diffusion -and perfusion weighted MRI for the prediction of volumetric response following uterine artery embolization in patients with symptomatic leiomyomas.

Intervention Description
MRI is a technique based on magnetic fields and does not require the use of ionizing radiation. Although there are no known side effects associated with MRI, a few precautions should be taken because of the 3T magnetic field. This implicates that all metal and magnetized objects must be removed from the patients before entering the MRI room. Patients with a pacemaker, a cardiac defibrillator or other implanted conductors/prostheses are for reason not eligible for the study. During the MRI examination, an intravenous contrast agent will be administered. In most cases, patients do not experience any discomfort and the use of this contrast agent is part of the clinical routine.

Time Frame
Participants will be followed for the duration of hospital stay (an expected average of 3 days) and will be systematically followed during their follow-up.
