Which imaging studies are typically performed to work up suspected appendicitis?

In the evaluation of suspected appendicitis, the most common imaging study utilized is a computed tomography (CT) scan of the abdomen and pelvis. A CT scan is particularly effective in diagnosing appendicitis as it provides detailed images that can show the presence of an enlarged or inflamed appendix, as well as any complications associated with appendicitis, such as abscess formation.

In conjunction with imaging studies, a complete blood count (CBC) is often performed to assess for signs of infection or inflammation. Typically, in cases of appendicitis, there can be elevated white blood cell counts indicating an inflammatory process.

Other imaging options, such as MRI and ultrasound, can be useful in specific populations (e.g., pregnant patients), but CT is generally preferred for the adult population due to its speed, accuracy, and ability to rule out other potential diagnoses. Thus, the combination of CT and CBC is a standard approach in the evaluation of suspected appendicitis.
