The prediction of vascular involvement by computed tomography (CT) with intravenous bolus contrast medium enhancement was compared to that of angiography in 31 patients with pancreatic carcinoma. CT was performed in 29 patients, angiography in 18 patients, while 16 had both investigations. Results of both radiological investigations were reviewed and compared with surgical findings. Sensitivity and specificity of CT was 88 and 100 percent respectively. Sensitivity and specificity of angiography was 57 and 100 percent respectively. The four false-negative results of CT concerned the superior mesenteric and portal veins. The ten false-negative results of angiography concerned the superior mesenteric and portal veins in four cases, and the celiac and superior mesenteric arteries in six cases. Comparison of results of CT and angiography revealed that the two methods concurred in 12 patients, five without and seven with vascular involvement. In three other cases, CT detected more abnormal vessels than angiography. In another case, only CT demonstrated nonresectability. In conclusion, CT with enhancement seems to be more accurate than angiography in the prediction of vascular involvement of pancreatic carcinoma.
对31例胰腺癌患者进行了研究，比较了静脉团注造影剂增强计算机断层扫描（CT）与血管造影对血管受累情况的预测。29例患者接受了CT检查，18例接受了血管造影检查，16例同时接受了这两项检查。对两项影像学检查结果进行了回顾，并与手术结果进行了比较。CT的敏感性和特异性分别为88%和100%。血管造影的敏感性和特异性分别为57%和100%。CT的4例假阴性结果涉及肠系膜上静脉和门静脉。血管造影的10例假阴性结果中，4例涉及肠系膜上静脉和门静脉，6例涉及腹腔干和肠系膜上动脉。CT与血管造影结果比较显示，两种方法在12例患者中结果一致，其中5例无血管受累，7例有血管受累。在另外3例中，CT检测到的异常血管比血管造影多。在另一例中，只有CT显示无法切除。总之，增强CT在预测胰腺癌血管受累方面似乎比血管造影更准确。
