What are other radiological tests that can be done in the diagnosis of intestinal diverticuli?
CT of the abdomen and pelvis (with oral and IV contrast). A small bowel follow through study can also be used to identify small bowel diverticula, but is limited for evaluation of diverticulitis.
There are multiple (at least two) small bowel out-pouchings at the terminal ileum at the right iliac fossa, the largest of which is medial in location and measuring 9.6 x 4.2 mm in size. The out-pouchings (diverticula) show mild oedematous wall changes and relatively augmented vascular signals on color Doppler evaluation with echogenic reactive omental fat surrounding their peripheral margins in keeping with an inflammatory process (diverticulitis).
Gut signature is maintained within the diverticula with no obvious perforation. The terminal ileum exhibits diffuse mucosal layers thickening consistent with terminal ileitis, but with maintained Kerckring folds (piano keyboard appearance). The appendix (well visualized extrinsically over the ipsilateral right iliopsoas muscle belly) shows no inflammatory changes or appendicolith and measures 4.2 mm in diameter.
