Overview

MRI is a good imaging modality that can be used in diagnosis of diverticulitis since it has an advantage that there is no exposure to the radiation and it rules out other abdominal causes of acute abdomen. However, it is not the best diagnostic procedure to diagnose diverticulitis and CT scan is more preferred. MRI shows specific findings of diverticulitis which include thickening of the colon wall, presence of the diverticula, and exudates out of the colon. It may also shows presence of multiple abscesses.
