A 49-year-old woman with uterine fibroid who experienced a substantial symptomatic improvement after treatment. (a) Pre-treatment and (b) post-treatment MR elastography images that correspond with the uterus superimposed on conventional MR images; (c) pre-treatment and (d) post-treatment sagittal T2-weighted images. Her fibroid showed a pre-treatment stiffness value of 5.7 kPa, which was lower than the average of this study. The fibroid volume was not decreased after MR-guided focused ultrasound (pre-treatment volume, 470 cm 3 ; post-treatment volume, 495 cm 3). However, her symptoms were substantially improved (pre-treatment Symptoms Severity Score, 90; post-treatment Symptoms Severity Score, 58; 37.8% decrease). The post-treatment stiffness value was decreased by 26% (from 5.7 kPa to 4.2 kPa). Oval regions of interest (circle), as large in size as possible, were placed on the fibroid.
