影响多排螺旋CT显示肝癌APS影像征象的因素分析

目的:研究肝癌APS的16层螺旋CT表现,分析影响16排螺旋CT显示肝癌APS影像征象的因素。方法:分析175例肝癌患者的16层螺旋CT扫描影像表现,对16层螺旋CT双期扫描显示的肿瘤大小、肿瘤位置、有无癌栓、分流位置等征象进行Logistic回归分析。结果:门静脉癌栓的相对危险度为1.05,肿瘤位置的相对危险度为1.60。其他相关征象在本研究中不是16排螺旋CT相关的肝癌APS显示影响因素。结论:影响16排螺旋CT显示肝癌APS影像征象的因素分别为门脉癌栓和肿瘤位置。

Analyse the Influence Factors on Multi-slice Computed Tomography in Diagnosing Hepatic Carcinoma with APS

Objective To study the findings of 16-slice CT in diagnosing the hepatic carcinoma with arterioportal shunt (APS),to Analyse the influence factors on multi-slice computed tomography in diagnosing hepatic carcinoma with APS.Methods The findings of 16-slice CT of 175 cases of hepatic carcinoma were analysed,The differences of the findings of hepatic carcinoma with APS on 16-slice CT were compared with those of DSA.The accuracy,sensitivity,specificity in diagnosing hepatic carcinoma with APS were analysed.Results 16-slice CT was superior to DSA on displaying the density differences and anatomic location of hepatic carcinoma with APS.2.Regard the DSA as the golden standard,the accuracy,sensitivity and specificity of the diagnoses on hepatic carcinoma with APS of 16-slice CT were as follows:98.8%,98.4%,99.1%,respectively.Conclusions 16-slice CT was superior to DSA in displaying the density differences and anatomic locations of hepatic carcinoma with APS.There was the higher the accuracy,sensitivity and specificity in the diagnosing of the hepatic carcinoma with APS using 16-slice CT.
