MR Imaging of Epithelial Ovarian Neoplasms Part I: Benign and Borderline.

Benign and borderline epithelial ovarian tumors represent a substantial proportion of incidental adnexal lesions and familiarity with the typical imaging features on MR imaging can aid in their diagnosis and management. Clinical information such as menstrual status, age, and associated conditions is also important considerations when evaluating an adnexal lesion. Radiologists play an integral role in the preoperative evaluation process and can help guide treatment, particularly in those with lesions demonstrating benign or borderline features and those who may be candidates for fertility-sparing surgery.
