多层螺旋CT三期扫描在小胰腺癌诊断中的价值

Multi-detector Row Helical CT in Diagnosing and Staging Small Pancreatic Adenocarcinoma

目的 :探讨多层螺旋CT三期扫描在小胰腺癌诊断和分期中的价值。方法 :对 8例胰腺癌患者行多层螺旋CT三期扫描 ,比较正常胰腺及肿瘤在各期的增强情况 ,做出可切除性评价 ,并与手术病理结果对照。结果 :三期扫描中 ,以胰腺期发现肿瘤最敏感。 8例肿瘤中 ,术前认为 6例可切除 ,术中切除 5例。结论 :多层螺旋CT三期扫描对小胰腺癌的早期诊断和可切除性判断有重要价值。

Objective:To evaluate the value of multiphase, multi detector row helical CT in detection and staging of small pancreatic adenocarcinoma.Methods:8 patients with small pancreatic adenocarcinoma underwent multiphase, multi detector row helical CT in the arterial phase (AP),!pancreatic parenchyma phase (PPP) and hepatic phase (HP). The enhancement of normal pancreas and tumor during the three phase were compared. The assessment of tumor, excision was compared with surgical and pathologic results.Results:Tumor pancreas contrast was significantly greater in PP than in the!other two phases. 6 of 8 cases were thought of being indications of excision before operation,and 5 were resected in the operation.Conclusion:Multi phase imaging of multi detector row helical CT play an important role in diagnosing and staging small pancreatic adeno carcinoma.
