Study Question: What are the factors associated with long-term success in patients with symptomatic uterine fibroids treated by magnetic resonance-guided focus ultrasound (MRgFUS) and can they be employed to create a clinically useful index that predicts long-term efficacy?
Summary Answer: Hypo-intense fibroids on T2-weighted magnetic resonance imaging (MRI) and older age were associated with higher success rates and can be used to predict success rates on the basis of their presence or absence as pre-treatment parameters.
What Is Known Already: The signal intensity of baseline T2-weighted MRI images and non-perfused volume at the end of the treatment can be correlated with MRgFUS outcome.
Study Design, Size And Duration: This was a retrospective analysis of 81 patients who were treated by MRgFUS for symptomatic uterine fibroids, in an academic affiliated center between 2003 and 2008.
