Computed tomographic arteriography of the liver

PC Freeny and WM Marks

Computed tomographic arteriography (CTA) is one method of evaluating hepatic masses. It consists of simultaneous infusion of 30% iodinated contrast medium into the hepatic artery during computed tomography (CT). Twenty-two patients with suspected resectable hepatic tumors were evaluated prior to surgery. Initial imaging procedures included conventional CT, ultrasonography, scintigraphy, and selective angiography. CTA identified additional tumor nodules in 12 out of 22 patients (55%), rendering the initially detected neoplasms unresectable. However, 2 other patients were found to have a normal liver and thus were spared unnecessary laparotomy.
