目的分析双源64层螺旋CT在肝外胆管癌诊断中的应用价值。方法对53肝外胆管癌患者的临床资料进行回顾性分析,所有患者均经手术病理结果确诊,均行双源64层螺旋CT检查,进行平扫、动脉期、门静脉期及延迟期扫描,同时进行三维重建,观察检查结果 ,分析影响学特征。结果 53例肝外胆管癌患者中经CT检查确诊51例,诊断正确率为96.2%;其中肝门部胆管癌诊断正确率为97.1%(33/34),中下段胆管癌诊断正确率为94.7%(18/19)。CT检出的51例患者中31例(60.8%)为肿块型,20例(39.2%)为管壁浸润型。结论双源64层螺旋CT在肝外胆管癌的临床诊断中具有重要的价值,能够提高诊断正确率,对指导临床治疗、改善患者预后方面具有重要意义,可作为诊断肝外胆管癌的首选检查方式在临床推广应用。
Objective To analyze the value of dual-source 64-slice spiral CT in the diagnosis of extrahepatic cholangiocarcinoma. Methods The clinical data of 53 patients with extrahepatic cholangiocarcinoma were retrospectively analyzed. All the patients were confirmed by pathology and pathology. Both patients underwent double-source 64-slice spiral CT scan and were scanned by plain scan, arterial phase, portal vein phase and delayed phase. Meanwhile, Perform 3D reconstruction, observe the inspection results and analyze the impact characteristics. Results Among the 53 patients with extrahepatic cholangiocarcinoma, 51 cases were diagnosed by CT, and the diagnostic accuracy was 96.2%. The correct diagnosis rate of hilar cholangiocarcinoma was 97.1% (33/34), and the diagnosis accuracy of middle and lower cholangiocarcinoma was 94.7 % (18/19). Among the 51 cases detected by CT, 31 cases (60.8%) were mass type and 20 cases (39.2%) were tubular infiltration type. Conclusion Dual-source 64-slice spiral CT has great value in the clinical diagnosis of extrahepatic cholangiocarcinoma, which can improve the accuracy of diagnosis. It is of great significance to guide the clinical treatment and improve the prognosis of patients and can be used as the first choice for diagnosis of extrahepatic cholangiocarcinoma Way to promote the clinical application.
