Abstract
Nineteen patients with suspected hepatic neoplasms underwent dynamic computed tomography (CT) and computed tomographic portography (CTP) in a preoperative setting. Nontumorous attenuation differences in the liver were observed in 8 patients (42%) with CTP and in 2 patients (10.5%) with dynamic CT (p<0.05).
Although nontumorous attenuation differences are significantly more frequent with CTP than with dynamic CT, they are seldom a diagnostic problem because of their geographic pattern.
