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.
At sonography the normal appendix is less frequently visualized, with results varying between 0-82% [1], reflecting the operator dependency of sonography. One of the most important imaging criteria in the evaluation of appendicitis is the outer diameter of the appendix. Although an overlap of appendiceal diameters in normal and inflamed appendices has been reported, a threshold value of 6-7 mm is most commonly used [1]. (Fig. 1).
