Nontumorous attenuation differences on computed tomographic portography.
Nineteen patients with suspected hepatic neoplasms underwent dynamic computed tomography (CT) and computed tomographic porotography (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 less than 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.
