Indications, advantages, and limitations of each of the imaging modalities
| Imaging modality | Indications | Advantages | Limitations |
| CT | Current imaging modality of choice for assessment of carcinomatosis in thorax, abdomen, and pelvis | Availability | Evaluation of mesenteric involvement and retraction Evaluation of small peritoneal deposits on bowel serosa |
| MRI | Allergy to iodine contrast medium Assessment of difficult-to-resect sites of disease | Optimal soft tissue contrast Detection of small peritoneal deposits Prediction of resectability | Duration of examination Limited to specialized centers |
| PET-CT | Suspected recurrence | Rapid identification of sites of recurrence | Lack of anatomic details |
| PET-MRI | Still to be defined | Optimal soft tissue contrast Rapid identification of sites of recurrence | Duration of examination Limited to a few centers Lack of experience |
