CT is a simple noninvasive method for evaluating inferior-vena-caval filters. The cross-sectional format offers an advantage over other techniques because the pericaval region is also evaluated. Thirteen patients scanned for localization and suspected complications of the Kimray-Greenfield filter revealed pericaval organ injury, retroperitoneal hematoma, and filter perforation. These events could only be inferred indirectly from other imaging techniques. In addition, CT easily demonstrated the position of the filter within the inferior vena cava and the relation of the filter to the renal veins. CT is a valuable adjunct to radiography, echography, and contrast venography in monitoring patients with Kimray-Greenfield filters.
CT是评估下腔静脉滤器的一种简单无创方法。其横断面成像方式相较于其他技术具有优势，因为它还能对腔静脉周围区域进行评估。对13例因金雷-格林菲尔德滤器定位及疑似并发症而进行扫描的患者进行检查，发现了腔静脉周围器官损伤、腹膜后血肿及滤器穿孔。而这些情况只能通过其他成像技术间接推断。此外，CT能轻易显示滤器在下腔静脉内的位置以及滤器与肾静脉的关系。在监测植入金雷-格林菲尔德滤器的患者时，CT是X线摄影、超声检查及静脉造影的一项有价值的辅助检查手段。
