The approach to imaging in pregnancy is unique, as it is essential to minimize radiation exposure to the fetus. Ultrasonography and magnetic resonance imaging are the chief modalities for evaluation of the pregnant patient with abdominal pain. ⋯ This article discusses test selection and underlying reasoning, with a description of common imaging features of different causes of acute abdominal pain in pregnancy. Also discussed are current evidence-based recommendations for the use of iodinated and gadolinium-based contrast agents and the importance of patient counseling.

ReviewMagnetic resonance imaging of female urethral and periurethral disorders.
This article reviews the normal anatomy of the female urethra, magnetic resonance (MR) imaging techniques, and the role of MR imaging in the evaluation of diverse urethral and periurethral diseases. Salient MR imaging findings of common and uncommon cystic urethral lesions (urethral diverticulum, Skene cyst, and vaginal cysts), and masses (urethral carcinoma, leiomyoma, melanoma, fibroepithelial polyp, caruncle, and mucosal prolapse) are presented. The evolving role of dynamic MR in the evaluation of stress urinary incontinence is reviewed.
