Transvaginal ultrasound is the method of first choice in patients with a suspected ovarian tumor. Computed tomography (CT) and magnetic resonance (MR) imaging are supplementary imaging procedures for the diagnostic evaluation of ovarian tumors. The major indications for a CT or MR examination are unclear ultrasound findings, the differential diagnosis of lesions and tumor staging. ⋯ CT and MR imaging use identical morphological criteria for the differentiation of benign and malignant ovarian tumors; MR imaging is not superior to CT. For the staging of ovarian carcinomas, CT is the preferred imaging procedure. Contrast-enhanced MR imaging might be better for the evaluation of peritoneal carcinosis than other modalities.
