... CT showed a high diagnostic accuracy, with a sensitivity of 92% and a specificity of 99%. In patients with acute abdominal syndrome, CT showed a diagnostic accuracy of acute cholecystitis comparable to ultrasound. The primary imaging modality for patients with suspicion of acute cholecystitis <nevertheless> should be ultrasound.
CT has the highest diagnostic accuracy of small bowel obstruction, sensitivity - 94%, specificity - 96%.
CT is an effective diagnostic method that has a positive effect on the treatment of a large number of patients with acute abdominal syndrome. Currently <2010> CT is the primary diagnostic modality for patients with acute abdominal syndrome, except in patients with suspected acute cholecystitis, when US is the preferred modality, although CT remains an acceptable alternative.

CT plays a certain role in confirming the diagnosis and staging in suspected complicated course of diverticulitis. CT provides information for determining tactics and in differential diagnosis, in accordance with the recommendations of the American Association of Colorectal Surgery.
