摘　　要：目的探讨256层螺旋CT动态容积扫描对肝门部胆管癌的诊断价值。方法对胆管癌病患30例采用256层螺旋CT技术,分析病患的肿块程度、密度及临床手术可行性。结果由F值检验可知,不同时期病灶检出情况有显著差异,其中平扫检出的肿块量最低。差异均有统计学意义(均P<0.05)。动脉期的肿瘤-肝CT值差为(26±9)HU均明显高于平扫期、门脉期。差异均有统计学意义(均P<0.05)。CT类型与手术类型大体一致,准确度为73.3%(22/30)。(根据Kappa检验,发现Kappa值>0.4。)CT评估与术中评估大体一致,准确度为73.3%(22/30)。(根据Kappa检验,发现Kappa值>0.4)。结论 256层螺旋CT动态容积扫描可清晰扫描出病患的肿块范围及密度,对手术分型及肿瘤的切除性评估也较为精确。意义远大,值得推荐。Objective To analyze the value of 256-slice spiral CT dynamic volume scanning in diagnosis of hilar cholangiocarcinoma.Methods From June 2012 to June 2014,in anus department in our hospital,30 cases of bile duct cancer underwent 256-slice spiral CT technology.We analzed type and degree of tumor on the mass,density,and the operability.Results The test by the F value of different period,lesion detection had significant differences,including plain scan detection mass minimum quantity.The differences were statistically significant(P <0.05).The arterial phase of tumor liver CT value difference of(26±9)HU were significantly higher than that of unenhanced phase,portal vein phase.The differences were statistically significant(P <0.05).CT type and operation types were generally consistent,the accuracy was73.3%(22/30).According to Kappa test,it was found that Kappa value was> 0.4CT evaluation and intraoperative evaluation was generally consistent,the accuracy was 73.3%(22/30).(according to Kappa test,it was found that Kappa value was> 0.4).Conclusion 256-slice spiral CT dynamic scanning volume can clearly scan mass range and density of patients for resection assessment,operation type and tumor in accurate.It is worthy of recommendation.
