MR Imaging of Epithelial Ovarian Neoplasms Part II: Malignant.

MR imaging shows high sensitivity and specificity for discriminating benign from malignant lesions, thereby aiding in cancer management from assessing the initial extent of disease to subsequent treatment response. Understanding the utility and application of advanced imaging techniques allows better lesion characterization. Subtypes of epithelial ovarian tumors are presented, along with characteristic imaging findings, and illustrated with examples. Select mimics of malignancy are also presented.
