Abstract:
Uterine artery embolization (UAE) is an effective treatment for symptomatic uterine fibroids. Magnetic resonance (MR) imaging is typically employed to evaluate the uterus following UAE for fibroid infarction, size, location change, persistent enhancement, changes in adenomyosis, and uterine necrosis. Variable pattern of calcification on computed tomography (CT) can differentiate embolic particles and fibroid involution. CT following UAE may be requested because of acute pelvic pain or chest discomfort or pyrexia and/or for complications that may require treatment in acute phase. Visualization of gas in uterus and uterine vessels following UAE is an expected finding that should not be misinterpreted as a sign of infection. The MRI and CT appearances vary depending upon the time interval after UAE and success of the procedure. Radiologists should be familiar with the range of post-UAE appearances on MRI and CT to better aid clinicians in correct diagnosis and treatment. The main purpose of this pictorial review is to identify the spectrum of findings on MRI and CT performed after UAE, to illustrate UAE-associated common and uncommon MRI and CT appearances and discuss post-UAE complications that require urgent medical or surgical intervention.
