title: Impact of high-resolution computed tomography of the pancreas on utilization of endoscopic retrograde cholangiopancreatography and angiography.
abstract: The impact of computed tomography (CT) on utilization of other diagnostic procedures was studied by comparing the results obtained in two groups of patients: (a) 278 patients studied prior to the availability of CT, and (b) 300 patients studied using CT. CT enabled an accurate diagnosis in 74% of patients without the use of additional examinations. Utilization of CT as the initial imaging procedure resulted in a decrease in the utilization of endoscopic retrograde cholangiopancreatography (ERCP) and angiography by 68% and 54%, respectively. This resulted in a 47% decrease in the overall cost of radiologic diagnosis.
