目的探讨多期CT增强扫描对胰腺癌临床分期的价值。方法回顾性分析30例经DSA、手术和病理证实的胰腺癌多期CT增强扫描的CT表现特点。结果28例正常胰腺实质血供丰富,26例胰腺癌为乏血供的肿瘤。胰头癌常使胰十二指肠动脉环向右移位,而十二指肠壶腹部肿瘤及胆总管下端肿瘤可将胰十二指肠动脉环向左推移。结论增强扫描对胰腺癌诊断、正确判断胰腺癌的临床分期及治疗方法选择十分重要。
Objective To investigate the value of multiphase contrast-enhanced CT in the clinical staging of pancreatic cancer. Methods CT features of multi-phase contrast-enhanced CT scans of pancreatic carcinoma confirmed by DSA, surgery, and pathology were retrospectively analyzed. Results The blood supply of 28 cases of normal pancreatic parenchyma was abundant, and 26 cases of pancreatic cancer were tumors with blood supply. Pancreatic head cancer often shifts the pancreaticoduodenal artery to the right, while the duodenal ampulla tumor and the common bile duct tumor can turn the pancreatic duodenal artery to the left. Conclusion The enhanced scan is very important for the diagnosis of pancreatic cancer and the correct clinical stage and treatment method for pancreatic cancer.
