摘　　要：目的探讨CT及MRI在胰腺钩突癌可切除性中的术前评估价值。方法回顾性分析1996年1月-2005年12月我科收治的57例胰腺钩突癌患者的CT及MRI表现,据此判断肿块能否切除,并将其结果与实际手术及病理报告相对照。结果CT及MRI判断胰腺钩突癌可切除的敏感性[=真阳性/(真阳性+假阴性)]为96.1%(49/51),特异性[=真阴性/(假阳性+真阴性)]为83.3%(5/6),阳性预测值[=真阳性/(真阳性+假阳性)]为98.0%(49/50),阴性预测值[=真阴性/(假阴性+真阴性)]为71.4%(5/7),准确率[=(真阳性+真阴性)/(假阳性+假阴性+真阳性+真阴性)]为94.7%(54/57),手术切除率89.5%。结论CT及MRI对胰腺钩突癌可切除性的评估有较高的价值,是外科医生术前评估的首选。Objective To study the value of CT and MRI conducted on resectability of uncinate process carcinoma of pancreas. Methods After retrospective analysis on CT and MRI carried out on 57 patients admitted in our department diagnosed as uncinate process carcinoma of pancreas, assessments were made on whether tumors can be resected or not. Comparison with the operative results and postoperative pathology reports was practised. Results According to CT and MRI, the sensitivity of uncinate process carcinoma resection rate was 96.1% （49/51 ）, specificity was 83.3 （5/6）, positive predictive value 98.0% （49/50）, negative predictive value 71.4% （5/7）, precision rate was 94.7%, and resection rate 87.8 %. Conclusion Assessment of CT and MRI conducted on resectat）ility of uncinate process carcinoma is possessed of relatively high value, and seems to be the preferable choice to the surgeon for preoperative evaluation.
