| 摘要 目的：探讨多层螺旋CT在胰腺癌中的诊断价值。方法：回顾性分析2017年2月至2019年2月我院接诊的72例经过手术病理证实的胰腺癌患者。比较多排螺旋CT平扫、动脉期、胰腺期、门脉期的检出率、神经、血管浸润情况、及选择55例正常胰腺组织比较两者多层螺旋CT扫描密度值的差异。结果：多层螺旋CT扫描，平扫、动脉期、胰腺期、门脉期检出率分别为63.89%、77.78%、95.83%、90.28%，胰腺期、门脉期检出率均显著高于平扫、动脉期（P＜0.05）；多层螺旋 CT 增强扫描诊断胰腺癌神经浸润的准确性为80.56%（58/72），敏感性为91.07%（51/56），特异性为43.75%（7/16），阳性预测值85.00%（51/60），阴性预测值58.33%（7/12）；多层螺旋 CT 增强扫描诊断胰腺癌血管浸润的准确性为95.83%（69/72），敏感性为80.00%（8/10），特异性为98.39%（61/62），阳性预测值88.89%（8/9），阴性预测值96.83%（61/63）；胰腺癌组织多层螺旋CT扫描密度值均显著高于正常胰腺组织密度值，（P＜0.05）。结论：多排螺旋CT在胰腺癌中诊断价值高，可帮助临床提供正确诊断，以选择合适的治疗方案。 |

| ABSTRACT Objective: To study Analysis of the diagnostic value of multislice CT in pancreatic cancer. Methods: Retrospective analysis was performed on 72 patients with pancreatic cancer confirmed by surgery and pathology from February 2017 to February 2019 in our hospital. To compare the detection rate, nerve and vascular infiltration, and the density of 55 normal pancreas tissues in multislice spiral CT plain scan, arterial phase, pancreatic phase and portal phase. Results: The detection rates of MSCT were 63.89%, 77.78%, 95.83% and 90.28% on plain scan, arterial scan, pancreatic scan and portal scan, respectively, which were significantly higher than those on plain scan and arterial scan (P<0.05). The accuracy of MSCT in the diagnosis of pancreatic cancer nerve infiltration was 80.56% (58/72), the sensitivity was 91.07% (51/56), the specificity was 43.75% (7/16), the positive predictive value was 85.00% (51/60), and the negative predictive value was 58.33% (7/12). The accuracy, sensitivity, specificity, positive predictive value and negative predictive value were 95.83% (69/72), 80.00% (8/10), 98.39% (61/62), 88.89% (8/9) and 96.83% (61/63) in the diagnosis of pancreatic cancer vascular infiltration by enhanced multislair CT. The density of pancreatic cancer tissues by MSCT was significantly higher than that of normal pancreas tissues (P<0.05). Conclusion: Multi-slice spiral CT has high diagnostic value in pancreatic cancer, which can help to provide correct diagnosis and select appropriate treatment. |
