What condition is primarily diagnosed by CT A/P with PO?

The condition that is primarily diagnosed by CT A/P with PO (Computed Tomography of the abdomen and pelvis with oral contrast) is diverticulitis. The use of CT imaging is crucial in evaluating this condition, as it allows for accurate visualization of the inflamed diverticula and any associated complications such as abscess formation or perforation. The oral contrast enhances the images and helps to delineate the bowel, providing clearer views of the surrounding structures and inflamed areas.

In the case of diverticulitis, the typical findings on a CT scan include thickening of the colonic wall, pericolonic fat stranding, and the presence of diverticula. The detailed imaging facilitated by CT aids in both diagnosis and in the assessment of the severity of the disease, guiding treatment decisions effectively.

Other conditions mentioned also can be evaluated through CT scans, but the combination of CT A/P with PO is particularly effective for diagnosing diverticulitis, making it the preferred modality in these cases.
