目的 探讨胰腺癌的影像学表现及各种影像学方法的临床应用价值。方法 回顾性分析我院 1989年至 1999年 46例经手术病理证实的胰腺癌 ,对照研究影像学表现 (US ,CT ,MRI,GI)与手术及病理所见 ,比较各种影像学检查方法的优缺点。结果 胰腺癌的影像学主要表现在以下几个方面 :①胰腺外形的变化 ,表现为胰腺增大和局部膨隆 ;②胰腺内肿块 ;③伴发胰、胆管扩张 ;④血管受侵 ;⑤邻近脏器受侵 ;⑥肝转移 ;⑦淋巴结转移。结论 影像学检查 ,尤其是 2种或 2种以上影像学检查联合应用 ,可为术前估计胰腺癌的可切除性及估计预后提供有价值的信息
Objective To investigate the imaging features of pancreatic cancer and the clinical application value of various imaging methods. Methods A retrospective analysis of 46 cases of pancreatic cancer confirmed by surgery and pathology in our hospital from 1989 to 1999 was conducted. Controlled imaging studies (US, CT, MRI, GI) were compared with surgical and pathological findings to compare various imaging methods. Advantages and disadvantages. Results The imaging of pancreatic cancer was mainly manifested in the following aspects: 1 Changes in the appearance of the pancreas, manifested as enlarged pancreas and partial bulging; 2 intrapancreatic masses; 3 associated pancreatic and bile duct dilatation; 4 vascular invasion; Invasion; 6 Liver metastasis; 7 Lymph node metastasis. Conclusion Imaging examination, especially the combination of two or more imaging examinations, can provide valuable information for estimating the resectability and estimating the prognosis of pancreatic cancer before operation.
