Contrast-enhanced MR arteriography to detect ovarian artery supply to uterine fibroids in patients scheduled for uterine artery embolization: Comparison with conventional angiography during uterine artery embolization for fibroids

100 patients with uterine leiomyomata scheduled for UAE were imaged contrast enhanced MR angiography before the procedure. Ovarian artery detection rates between CE MRA and conventional angiography were compared. The sensitivity, specificity, PPV, and NPV of CE MRA for detecting ovarian arteries supply to the uterus and/or fibroid was 71.4%, 89.2%, 66.7% and 97.6%, respectively. Our results suggest a potential role for CE MRA pre-UAE because a negative CE MRA may eliminate the need for routine aortography during UAE.
