What is a common indication for performing a CT Abd/Pel with PO contrast?

A common indication for performing a CT Abd/Pel with oral contrast is to evaluate conditions affecting the gastrointestinal tract, with diverticulitis being a prime example. In diverticulitis, the colon's diverticula become inflamed or infected, and the use of oral contrast can enhance the visualization of the colonic walls and any associated complications, such as abscesses or perforations. This imaging technique allows for a more accurate assessment of the extent of the disease and aids in determining the appropriate treatment plan.

The other conditions mentioned do not typically require CT Abd/Pel with oral contrast. Pneumothorax is generally assessed through chest imaging, joint injuries are evaluated via musculoskeletal imaging techniques, and carotid dissections are usually assessed with vascular imaging protocols, often using CT Angiography rather than abdominal/pelvic CT.
