MR of gynaecologic disease in pregnancy

Abstract

MR imaging to investigate gynaecologic pathology in pregnancy typically follows clinical and US assessment, and there is usually a provisional diagnosis that requires further imaging assessment for confirmation. The MR examination can be tailored to the clinical question in order to limit scan time and improve diagnostic yield. Gynaecologic disease may be pre-existing, incidentally detected or occur as a result of pregnancy. We review normal MR appearances of the uterus, cervix and adnexa and then discuss MR appearances of a wide variety of interesting and complex scenarios including – cervical cancer in pregnancy, adnexal masses, uterine fibroids and their complications and finally a discussion of rarer presentations including gestational trophoblastic neoplasia. MR is a useful problem-solving tool in the evaluation of gynaecologic pathology in pregnant women.
