| 摘 要：［目的］ 评价CT和MRI术前判断胰腺癌手术可切除性的应用价值。［方法］ 回顾性分析经病理证实的40例胰腺癌的CT和MRI征象，包括肿瘤大小、边界、血管侵犯、淋巴结转移及远处转移，并与手术及病理对照。［结果］ 术前影像学显示肿瘤大小平均4.5cm，边界清晰18例，血管受累不可切除26例，淋巴结转移21例，肝脏转移8例，腹膜及远处转移6例。术前影像学对于血管可切除性、淋巴结转移诊断的灵敏度、特异性、准确率分别为76.9%、40.7%、52.5%和70.0%、65.0%、67.5%。手术可切除组和不可切除组肿瘤大小（P=0.546）和肿瘤边界（P=0.053）没有统计学差异。［结论］ CT和MRI是评估胰腺癌可切除性的有效方法。 |

| Abstract：［Purpose］ To investigate the application of CT and MRI in predicting resectability of pancreatic adenocarcinoma.［Methods］ The CT and MRI findings of 40 patients with pancreatic adenocarcinoma were retrospectively analyzed，including mass diameter，boundary，vessel involvement，metastatic lymph nodes and distance metastasis.［Results］ The mean diameter of the tumors was 4.5cm. The number of the cases with clear boundary，vessel involvement，metastastic lymph nodes and distance metastasis were 18，26，21，8 and 6 respectively. The sensitivity，specificity and accuracy of vessel involvement，metastatic lymph nodes were 76.9%，40.7%，52.5% and 70.0%，65.0% and 67.5% respectively. No difference was detected between the resectable and unresectabel group in mass diameter(P=0.546) and boundary(P=0.053). ［Conclusion］ CT and MRI are effective methods in predicting the resectability of pancreatic carcinoma. |
