Technique and diagnostic utility of saline infusion sonohysterography

The introduction of saline infusion sonohysterography has significantly improved sonographic diagnosis of various endometrial pathologies. This procedure entails instillation of warm saline into the uterine cavity transcervically to provide enhanced visualization of the endometrium during transvaginal ultrasound examination. This article reviews the sonohysterography technique and current utility, as well as the spectrum of imaging features of various endometrial pathologies.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/135202/1/ijgo5.pd

CT and MRI features following Uterine Fibroid Embolization

Uterine artery embolization (UAE) is an effective treatment for symptomaticuterine 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 requires urgent medical or surgical intervention Uterine artery embolization (UAE) is an effective treatment for symptomaticuterine fibroids.
