A prospective study evaluating diffusion weighted magnetic resonance imaging (DW-MRI) in the detection of peritoneal carcinomatosis in suspected gynecologic malignancies.

•Diffusion-weighted MRI (DW-MRI) is superior to CT in detecting right diaphragm disease found at surgery.•DW-MRI and CT are equivalent in detecting disease involving the majority of sites important for surgical planning.•Interobserver radiologist agreement is better for DW-MRI than for CT in detecting disease found at the time of surgery.
