Comparison of MRI and CT for Predicting the Peritoneal Cancer Index (PCI) Preoperatively in Patients Being Considered for Cytoreductive Surgical Procedures

To compare the accuracy of MRI and CT for predicting the Peritoneal Cancer Index (PCI) preoperatively compared with the PCI tabulated at surgery. Twenty-two patients underwent preoperative MRI and CT scanning followed by cytoreductive surgery for appendiceal (n = 17) and ovarian (n = 5) cancer. MR and CT examinations were retrospectively reviewed to determine the PCI. The results of these scores were compared with PCI tabulated at surgery....
