ResumoThirty-three patients with ovarian carcinoma who had no evidence of metastases or ascites demonstrated on computed tomography (CT) with and without contrast agent were examined with CT after injection of approximately 3000 cc of a 2.4% solution of nonionic contrast media into the peritoneum. After intraperitoneal injection with CT (IPC CT), 22 were diagnosed as having intraperitoneal metastases. Of these, 19 were found to be true positives and 3 false negatives. Three other patients diagnosed as normal were found to have metastases. In all patients the peritoneum was well outlined and generally any metastases smaller than 1 cm were demonstrated. It was possible to identify compartmentalization of the peritoneum and to determine the location of the lesion to be in the peritoneum or the extraperitoneal space. This information is necessary in the planning of chemotherapy, particularly endoperitoneal chemotherapy. Tiny metastases to the omentum or adherent loops of small bowel could not be seen well.
