Randomized Controlled Trial Comparative Study Clinical Trial
Suspected appendicitis in children: US and CT--a prospective randomized study.
To evaluate the accuracy of ultrasonography (US) and of abdominal computed tomography (CT) performed in addition to US in the diagnosis of childhood appendicitis. ⋯ US is valuable in the diagnosis of appendicitis in children. In inconclusive cases, performing additional abdominal CT can improve diagnostic accuracy and thereby decrease the negative appendectomy rate without an increase in the perforation rate.
