During computed tomography (CT) scanning of the liver, the inferior vena cava can be identified as a separate structure of lesser density adjacent to the caudate lobe in two-thirds of patients without known hepatocellular disease. In patients with alcoholic (portal) cirrhosis of moderate to severe degree, intrahepatic portal veins may not be identified on CT scans, even though their inferior vena cavas can be definitely distinguished from the caudate lobe. Portal cirrhosis causes distortion and obliteration of the portal triads, which is presumably reflected by lack of visualization of intrahepatic portal veins during CT scanning.
在对肝脏进行计算机断层扫描（CT）时，在三分之二无已知肝细胞疾病的患者中，下腔静脉可被识别为与尾状叶相邻的密度较低的独立结构。在中度至重度酒精性（门静脉）肝硬化患者中，即使其下腔静脉可与尾状叶明确区分，但在CT扫描上可能无法识别肝内门静脉。门静脉肝硬化会导致门静脉三联征扭曲和闭塞，这可能是CT扫描时肝内门静脉无法显影的原因。
