目的 探究64层螺旋CT在胰腺癌术前分期中的应用价值。方法 以2010年2月~2015年6月我院收治的45例胰腺癌患者为 研究对象，病例患者均行64层螺旋CT扫描，分析胰腺癌患者64层螺旋CT影像学表现，并与手术病理结果进行对照分析，探 究64层螺旋CT在胰腺癌术前分期中的应用价值。结果 64层螺旋CT平扫显示胰腺肿大、形态不规则、病灶区密度不均，经 增强扫描早期提示胰腺实质内低密度影；64层螺旋CT扫描胰腺癌时可清晰显示肿瘤灶与周围组织结构之间的关系。64层螺 旋CT诊断胰腺癌敏感度、特异度、准确度参照病理结果分别为77.78%（35/45）、0（0/0）、77.78%（35/45）。64层螺旋 CT对胰腺癌术前进展期（Ⅱ期、Ⅲ期、Ⅳ期）诊断准确率与病理检查结果相较无明显差异（P>0.05）。结论 64层螺旋CT 对胰腺癌诊断准确性较高，在胰腺癌术前分期中尤其是进展期有较高诊断价值，对指导手术方案制定有着重要临床意义。

Objective To explore the application value of 64 slice spiral CT in preoperative staging of pancreatic carcinoma. Methods A total of 45 patients with pancreatic carcinoma admitted to our hospital from February 2010 to June 2015 were selected as study subjects. All patients underwent 64 slice spiral CT scan, and the imaging findings were analyzed and compared with the results of surgery and pathology. The application value of 64 slice spiral CT in preoperative staging of pancreatic carcinoma was analyzed. Results Imaging findings of 64 slice spiral CT scan showed that the enlargement of the pancreas, irregular shape and uneven density of lesions, and the enhanced scan indicated pancreatic parenchymal low density. 64 slice spiral CT scanning of pancreatic carcinoma could clearly show the relationship between the tumor and surrounding tissue structures. The sensitivity, specificity and accuracy of 64 slice spiral CT in the diagnosis of pancreatic carcinoma were 77.78% (35/45), 0 (0/0) and 77.78% (35/45), respectively. The accuracy of 64 slice spiral CT in the diagnosis of preoperative staging (stage Ⅱ, Ⅲ, Ⅳ) of pancreatic carcinoma showed no significant difference (P>0.05). Conclusion 64 slice spiral CT is highly accurate in the diagnosis of pancreatic carcinoma. It is of high diagnostic value in preoperative staging of pancreatic carcinoma, especially in the advanced stage, which is of great importance for the development of treatment plan.
