摘　　要：目的探讨多排螺旋CT多期扫描技术在胰腺癌中的诊断价值。方法选取做过多排螺旋CT的动脉期、实质期、静脉期三期扫描胰腺肿块的患者83例,均由病理切片证实,其中胰腺癌38例,胰腺炎45例,比较胰腺炎和胰腺癌强化后的CT值。结果螺旋CT多期扫描能够显示肿瘤的部位、大小、形状和密度,还能清楚显示肿瘤与周边器官和血管的关系。胰腺癌出现腹膜后淋巴结转移37例,腹腔动脉受累32例,肠系膜上静脉受累29例,肝转移17例、胰管扩张36例、胆囊壁增厚32例,而胰腺炎患者仅出现胰管扩张9例、胆囊壁增厚10例。在胰腺的实质期强化效果最好,且胰腺实质的强化和肿瘤组织的对比显著,差异有统计学意义(P<0.05)。结论多排螺旋CT在动脉期、实质期、静脉期三期增强扫描对于胰腺癌诊断具有非常重要的价值。Objective To investigate the value of multi-phase technique of multi-slice spiral CT in the diag- nosis of pancreatic carcinoma. Methods A total of 83 patients with pancreatic masses treated by multi-slice spiral CT in the arterial phase, parenchymal phase, venous phase were enrolled in the study. All the patients were confirmed by pathological examination, including 38 cases of pancreatic carcinoma and 45 cases of acute panereatitis. The en- hanced CT values were compared between pancreatitis and pancreatic carcinoma. Results Multi-slice spiral CT scan can show the tumor location, size, shape and density, as well as the relationships of tumor with the surrounding organs and blood vessels. For patients with pancreatic cancer, there were 37 cases of retroperitoneal lymph node metastasis, 32 cases of celiac artery, 29 cases of superior mesenterie vein, 17 eases of liver metastasis, 36 cases of pancreatic duet dilatation, 32 cases of gallbladder wall thickening. For patients with pancreatitis, there were 9 cases of pancreatic duct dilatation and I0 cases of gallbladder wall thickening. The enhancement effect was good in the parenchymal phase, and statistically significant difference was found between pancreatic parenchyma and pancreatic carcinoma （P〈0.05）. Conclusion Enhanced scan by multi-slice spiral CT in the arterial phase, parenchymal phase, and venous phase is of great value in the diagnosis of pancreatic carcinoma.
