摘　　要：目的　探讨胰腺癌的 CT诊断价值。方法　对 76例胰腺癌的 CT表现进行分析并与手术病理结果对照。结果　 1胰腺癌在 CT上表现为低密度的肿块 ,不强化或强化不明显 ,肿块边缘不规则强化 ;2胰头癌可引起胆总管、胰管的扩张 ;3胰腺癌多伴邻近血管及脏器受侵。结论　 CT能正确评价胰腺癌及胰周浸润 。Objective To explore CT diagnostic importance on invasion of adjacent structures by pancreatic adenocarcinoma.Methods The CT findings and clinical symptoms in 76 cases with pancreatic adenocarcinoma were analysed.Results 1) Pancreatic adenocarcinoma has generally been described as focal regions of hypoattenuation as compared with the normal pancreas.2) Sequence of images demonstrated a dilated pancreatic duct with a mass seen in the head of pancreas.3) Carcinoma infiltrating the body and tail of the pancreas sequencely invaded the surrounding structures. Conclusion CT is very valuable in diagnosing pancreatic carcinoma and its invasion of surrounding structures. Thus it is an important diagnostic measure to decide whether pancreatectomy can or should be done.
