The value of multi -detector row heli cal CT in diagnosing and staging pancreatic adenocarcinoma

目的评价多层螺旋CT三期扫描在胰腺癌诊断和分期中的价值。方法对临床拟诊的胰腺癌患者28例行动脉期、胰腺期、肝脏期三期扫描,延迟时间分别为20s、38s和75s,与病理结果对照,分析其诊断及可切除性评价的正确性。结果28例CT诊断的胰腺癌中,26例正确诊断,诊断正确率为93%,2例因淋巴结转移不可切除的肿瘤,术前CT诊断为可以切除,其余24例均正确分期。结论多层螺旋CT三期扫描以提供极好的影像质量在胰腺癌诊断和可切除性评价方面具有重要价值。

Objective To evaluate the value of multi -detec tor row helical CT in diagnosing and s taging pancreatic adenocarcino-ma.Methods Twenty -eight patients with suspect ed pancreatic adenocarcinoma underwent multiphase,contrast -enhance d,multi -detector row helical CT during the artrial phase(AP),pancreatic parenchymal phase(ppp),and hepatic phase(HP).The delayed scans started at20s.38s and 75s respectively,after intravenous injection of contrast m aterial.Diagnostic accuracy and re sectability determination of pan-creatic adenocarcinoma were compared with surgical and histo -patholog ical findings.Results Among twenty -eight patients with su specteol pancreatic adenocarcinoma,multi -detector row helical CT accurately d emonstrated 26casse(accuracy of 93%).Two patients considered resectable on the basis of CT findings were found to be unresectable at sur gery because of lymph node metastasis,whereas others were correct staging.Conclusion Multi -phase image of multi -detecto r row helical CT plays important role in diagnosing and stanging pancreatic adenocarcinoma as it provides excellent image quality.[
