Overview
On abdominal MRI, diverticulitis is characterized by thickening of the colon wall, the presence of the diverticula, and exudates from the colon. It may also show the presence of multiple abscesses. MRI is a good imaging modality that can be used in the diagnosis of diverticulitis since it has the advantage that it does not involve exposure to radiation and rules out other abdominal causes of acute abdomen. However, MRI is not the best diagnostic procedure for diverticulitis; CT scan is preferred.[1][2]
MRI
MRI shows the following findings in diverticulitis patients:[3][4]
- Wall thickness of the colon
- Presence of diverticula
- Exudates and edema out of the colon
- Abscesses
- Fatty infiltration in the colon
- Segmental narrowing of the colon
