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.
This means the test is very specific for appendicitis, but is not very sensitive. The patient may have acute appendicitis, but it may be missed because the appendix is not visualized. For example, if the appendix is retrocecal (behind the right side of the colon), or if the patient is too obese to scan accurately, it may not be seen and another test may be needed. CT Scan. In many places abdominal CT scan has become the test used most often to make the definitive diagnosis of appendicitis. Until recently, obese patients and elderly patients with other conditions would undergo CT scans of the abdomen instead of ultrasound.
