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.
19例疑似肝脏肿瘤患者在术前接受了动态计算机断层扫描（CT）和计算机断层扫描门静脉造影（CTP）。CTP检查发现8例患者（42%）肝脏存在非肿瘤性衰减差异，动态CT检查发现2例患者（10.5%）存在该差异（p<0.05）。虽然CTP检查发现非肿瘤性衰减差异的频率显著高于动态CT，但由于其呈地图样分布，很少会造成诊断问题。
