摘要
目的应用CT仿真内镜(CTVE)技术比较不同的对比剂(充气或充水)充盈方法对猪空肠同等直径、不同高度的隆起性病变的显示能力。方法取离体猪小肠标本20段,于内壁模拟同等直径、高度分别为5、10、15 mm形态各异的两组肿瘤性病变,将20段小肠随机分为充气组和充水组,每组各10段,行多层螺旋CT(multislice CT,MSCT)扫描,利用工作站进行CTVE成像,比较应用不同充盈方法对猪空肠占位性病变的检出情况。采用SPSS 16.0软件进行统计学分析。结果 CTVE技术诊断两组间病变:在模拟占位的显示上,高度5 mm的病灶,两组间对病灶的显示差异有统计学意义(P<0.05),充气组优于充水组;高度10 mm的病灶,两组间对病灶的显示差异有统计学意义(P<0.05),充气组优于充水组;高度15 mm的病灶,两组间对病灶的显示差异无统计学意义(P>0.05)。结论对于同等直径的高度5 mm和10 mm的模拟占位,气体充盈优于水充盈者,更适合于黏膜面的显示,提高小病灶的检出率。
Objective To applicate CT virtual endoscopy（computed tomographic virtual endoscopy,CTVE） technology to compare the display capability with different contrast agent（air or water） filling methods of porcine jejunal equivalent diameter of different height of the elevated lesion.Methods The pig′s small intestine were divided into 20 specimens,each one were simulated tumor lesions with equivalent diameter 5 mm and 10 mm,15 mm,20 small intestine were divided into inflatable group and water-filled group,there were 10 specimens in each group,take MSCT scanning,using of workstation CTVE imaging to compare the different filling of the pig jejunum of the detection of lesions. Statistical analysis was performed using SPSS 16.0 software.Results Between the two groups,in a simulated mass, with 5 mm in height,there were significantly（P 0.05）,inflation group were better than the water-filled group;about height 10 mm,between the two groups there were significantly difference（P 0.05）,inflatable group was better than water-filled group;with height 15 mm lesions,there was no significant difference（P 0.05）.Conclusion For the same height of 5 mm and 10 mm diameter of simulated mass,filling the gas is better than water;for displaying mucosal surface,and to improve the detection rate of small lesions.
