The findings of this study underscore the superior sensitivity of MRI, particularly when incorporating advanced sequences like DWI and T1 out-of-phase imaging, in detecting peritoneal carcinomatosis compared to CT. These techniques provide critical information that can alter disease staging and influence treatment planning, including the identification of local invasion into structures such as the bowel wall. Based on these results, the integration of such MRI sequences into routine clinical protocols is recommended to enhance diagnostic accuracy and optimize patient management in suspected cases of peritoneal carcinomatosis.

The enhanced detection capabilities of MRI may lead to earlier and more accurate staging of peritoneal carcinomatosis, particularly by revealing subtle lesions and local invasion that might be overlooked on CT. This improvement in diagnostic accuracy is significant for therapeutic decision-making, where precise delineation of disease extent is essential for planning surgical or chemotherapeutic interventions. Future studies with larger patient cohorts are warranted to further validate these findings and help establish standardized imaging protocols.
