CT-MR Findings in Ovarian Cancer
Ovarian cancer is the most lethal of the gynecologic cancers as the majority of patients will have advanced disease at time of presentation. The most important determinant of survival for ovarian cancer patients is the disease stage at diagnosis and maximum residual disease after cytoreductive surgery. Cross-sectional imaging has an invaluable role in the preoperative surgical and management planning of these patients. A TNM (tumor, nodes, metastasis) classification has been defined, with the definitions of the T stage categories corresponding to several stages accepted by FIGO. CT is the imaging modality of choice for noninvasive staging and follow-up in ovarian cancer because it is quick, widely available, and reproducible. MRI is a problem-solving tool in the characterization of the origin and morphologic features of indeterminate ovarian masses and is particularly useful for local staging. DWI seems a new promising technique for the depiction of peritoneal metastases, when combined with conventional imaging.
