胰腺癌的CT表现

目的探讨胰腺癌的CT表现。方法回顾性分析44例经手术病理及临床证实的胰腺癌患者的CT表现，分别对胰腺癌和正常胰腺胰腺期、门脉期密度进行比较。结果28例病变位于胰腺头部，7例位于胰腺体部，6例位于胰腺尾部，3例为弥漫性胰腺癌。胆管扩张24例，胰管扩张25例，肝内转移12例，淋巴结转移35例。44例病例中有36例行双期增强扫描，表现胰腺期胰腺癌与正常胰腺密度差别最大。结论CT扫描可以明确胰腺癌的存在以及周围侵犯和转移情况，胰腺期扫描对识别胰腺癌尤为重要。

A Study on CT Features Of Pancreatic Carcinoma

Objective To explore the CT features of pancreatic carcinoma. Methods CT expressions of 44 patients with pancreatic carcinoma proved by clinical data or pathology were analyzed retrospectively,and made a comparative analysis on CT attenuation values of arterial stage scanning and portal stage scanning of tumor-pancreas respectively. Results The space-occupying lesions of pancreatic head, pancreatic body and pancreatic tail were 28 cases,7 cases and 6 cases respectively, and three cases of diffuse pancreatic carcinoma were diagnosed. 24 cases of biliary dilatation and 25 cases of pancreatic duct dilatation, 12 cases of intrahepatic metastasis and 35 cases of lymphatic metastasis existed. 36 patients in our study underwent dual-phase enhancement scanning,and the maximum dense difference of tumor-pancreas was significantly on pancreatic phase. Conclusions CT scanning can confirm the existence, erosion and metastasis of pancreatic carcinoma, and pancreatic phase scanning is especially significant for diagnosing tumor.
