Answer

Abdominal computed tomography (CT) scanning is the imaging modality of choice for C difficile colitis when pseudomembranous colitis (see the image below), complications of CDI, or other intra-abdominal pathology is suspected. [4] In patients with sepsis due to suspected megacolon, abdominal radiography may be performed instead of CT scanning to establish the presence of megacolon in a timely manner.

Clostridioides (Clostridium) difficile colitis. Co Clostridioides (Clostridium) difficile colitis. Computed tomography scan of pseudomembranous colitis.
