摘要

Acute abdomen is a common presentation in emergency medicine. It represents 5% to 10% of all Emergency Department (ED) visits. Diagnosis by imaging includes digital X-ray unit, sonography (US) unit and computed tomography (CT) equipment. During the last years, a trend towards increased use of computed tomography in patients with acute abdomen can be seen. Additionally, patient with severe claustrophobic often cannot tolerate MR scanner. The aim of the present study was to investigate the possibility of optimizing Helical CT parameters in the protocol and emphasize the CT features of selected cases of disorders related acute abdominal complain at the Emergency Department both in general and in a number of selected conditions (Urolithiasis, Aortic Aneurysm Rupture and acute cholecystitis). According to this work findings, non-contrast CT after ultrasound is diagnostic modality for patients with urinary stones in the Emergency Department. Contrast-enhanced CT was highly sensitive for acute aortic syndrome and therefore the CT imaging protocols must be adjusted in order to minimize dose from radiation.
