Failure to visualise the intra-abdominal portion of the inferior vena cava (IVC) using contrast-enhanced computed tomography (CT) is unusual. A review of 1272 contrast-enhanced abdominal CT examinations revealed that the IVC was not visible at one or more levels in only 132 (10.4%). In 57 (43%), non-visualisation was due to pathological processes, most frequently metastatic carcinoma, causing compression or thrombosis of the IVC. In the remainder, technical factors or artefacts could explain the non-visualisation. Techniques and procedures to improve visualisation of the IVC are discussed. Failure to visualise the IVC on CT at any level unexplained by artefacts is abnormal.
使用对比增强计算机断层扫描（CT）未能显示下腔静脉（IVC）的腹内部分是不常见的。对1272例对比增强腹部CT检查的回顾显示，仅132例（10.4%）在一个或多个层面上看不到IVC。在57例（43%）中，未能显示是由于病理过程，最常见的是转移性癌，导致IVC受压或血栓形成。在其余病例中，技术因素或伪影可解释未能显示的原因。讨论了改善IVC显示的技术和程序。在CT上未能在任何层面显示IVC且无法用伪影解释是异常的。
