The acute abdomen: Computed tomography

Michael P. Federle M.D.1

1 From the Department of Radiology, San Francisco General Hospital, San Francisco

Computed tomography is a very versatile and valuable tool in evaluation of patients with acute abdominal conditions. For blunt upper abdominal trauma, including suspected splenic rupture, it is the diagnostic procedure of choice. For evaluating the extent of an abscess, including subhepatic abscess, for directing catheter drainage, or for confidently excluding abscess, CT is, in my opinion, also the single best modality. When acute cholecystitis is the leading clinical diagnosis, CT defers to sonography and cholescintigraphy, and is mainly employed to evaluate complications of acute cholecystitis such as abscess. When acute cholecystitis is one of many possible causes of acute symptoms, CT and sonography provide a more comprehensive evaluation of the upper abdomen than do other imaging modalities.
