目的评价16排螺旋CT血管成像诊断肾动脉病变的临床应用价值。方法对500例肾脏病变高血压患者行16排CT连续容积扫描,以CT轴位薄切图像(层厚1.25mm,间隔1.25mm为原始数据,然后应用GEAW4.2工作站进行双肾动脉图像后处理,结合多种重建图像综合分析。结果 500例中共显示肾动脉1032条,部分显示一侧或双侧双肾动脉供血,主肾动脉皆显示清晰,级分支显示率95.3%,级以下分支能够清晰显示,显示率95%。结论 SCTA能如实显示肾动脉狭窄的部位和程度,具有重要的临床价值,完全可取代血管造影。
Objective To evaluate the clinical value of 16-slice spiral CT angiography in the diagnosis of renal artery lesions. Methods A total of 500 patients with renal disease and hypertension were scanned with 16-slice CT. The axial CT images (thickness 1.25mm, interval 1.25mm) were used as the raw data, and then the GEAW 4.2 workstation was used to perform the post-treatment of the renal arteries , Combined with a comprehensive analysis of a variety of reconstruction images.Results 500 cases showed renal artery 1032, part of the bilateral renal artery or bilateral blood supply, the main renal artery were clear, the level of the branch showed 95.3%, below the level of branches can be clear Showed that the display rate of 95% .Conclusion SCTA can accurately show the location and extent of renal artery stenosis, has important clinical value, completely replace angiography.
