MR Imaging in Corpus Neoplasia: Spectrum of MR Findings

MR imaging is a noninvasive and a useful modality for depicting a wide variety of uterine tumors with excellent tissue contrast. In case malignant uterine neoplasms are suspected, contrast-enhanced image is useful to delineate the tumor extent and internal architecture of the tumor. In cases of endometrial carcinomas, dynamic enhanced imaging is utilized for evaluating the depth of myometrial invasion. In differentiating malignant uterine tumors from benign conditions, in addition to filtration into the surrounding tissues, the presence of necrosis that is usually better demonstrated on postcontrast images is important imaging finding. Diffusion-weighted imaging is an emerging technique that depicts tissue contrast based on restricted diffusion of water molecules and demonstrates increased intensity in the malignant tumors. The recognition of typical MR imaging features in a wide variety of endometrial tumors may facilitate differentiation, thus better determining appropriate patient management.
