Computerized tomography (CT) scan. In patients who are not pregnant, a CT scan (a type of X-ray study) of the area of the appendix is useful in diagnosing appendicitis and peri-appendiceal abscesses as well as in excluding other diseases inside the abdomen and pelvis that can mimic appendicitis.
The diagnosis of appendicitis is largely based on the person's signs and symptoms. In cases where the diagnosis cannot be made based on the person's history and physical exam, close observation, radiographic imaging and laboratory tests can be helpful.
