BACKGROUND: To compare CT and MRI for peritoneal carcinomatosis index (PCI) assessment and to compare assessments made by the radiologist based on their experiences. METHOD AND MATERIALS: MRI and CT of abdomen and pelvis were performed on 39 prospectively followed by surgery directly. Two blinded radiologists with different experience levels evaluated PCI separately on different occasions on 19 cases initially and later on the remaining 20. The agreement between the radiologists' assessment and surgical findings in total and per site were recorded. RESULTS: Total PCI: The experienced radiologist was able to assess total tumor burden correctly on both CT and MRI (kappa = 1.0). For the inexperienced radiologist the assessment was better on CT (kappa = 0.73) compared to MRI (kappa = 0.58). Different sites: The experienced radiologist showed high agreement with kappa = 0.77 for MRI and 0.80 for CT. Corresponding figures were 0.39 and 0.60 for the inexperienced radiologist. For the second phase the agreement levels increased for the inexperienced radiologist increased to 0.80 and 0.70, respectively. CONCLUSION: CT and MRI are equal when read by experienced radiologist. CT shows better results when read by an inexperienced radiologist compared to MRI, however the results of the latter can easily be improved.
