多层螺旋CT仿真血管镜在动脉硬化症诊断中的临床应用

Clinical Application of Multi-Slice CT Virtual Intravascular Endoscopy in Diagnosis of Arteriosclerosis

    摘要
  • 摘要: <b<目的：</b< 探讨动脉硬化症的多层螺旋CT仿真血管镜改变及诊断价值。 <b<方法：</b< 回顾性分析40例正常人血管及24例临床诊断为动脉硬化症血管的多层螺旋CT扫描资料,将所有的CT图像进行低对比(kernel≤30f)薄层(slice≤3mm)重建,然后将重建图像导入CT 3D工作站,用软件CT仿真内窥镜(CT-VE)、多平面成像(MPR)、最大密度投影(MIP)、容积成像技术(VRT)进行图像后处理,并就正常血管及病变血管在CT仿真血管镜中的改变进行分析和记录。 <b<结果：</b< 64例均成功地进行了CT仿真血管镜成像,40例正常组的血管仿真血管镜图像表现为血管壁光滑,管腔无狭窄;24例病变血管中,血管壁钙化24例78处,血管内壁不规则及增厚24例,血管狭窄21例。动脉硬化斑块15例48处。 <b<结论：</b< 多层螺旋CT仿真血管镜是诊断动脉硬化症的一种有效方法,其优势在于检查快速和无创伤性。

     

    Abstract: <b<Objective</b< To investigate manifestations of the multi-slice CT Virtual Intravascular Endoscopy (MSCT-VIE) in the arteriosclerosis and it's diagnostic value. <b<Methods</b< 40 cases in normal group and 24 cases of arteriosclerosis group were performed volume scan with SIEMENS Sensation 4 MSCT, Then the raw data was reconstructed with lowly kernel(kernel ≤ 30f) and thin slice (slice ≤ 3mm), and transmitted to CT 3D workstation, All images post process were performed by computed tomography virtual endoscopy (CT-VE), Multiplanar reconstructions(MPR), Maximum intensity projection(MIP) and volume reconstruction technique(VRT) software, The manifestations of lesions vessel of MSCT-VIE were analyzed and recorded. <b<Result</b< Among 64 cases, 24 cases of 78 lesions of calcifications, 24 cases with irregular inside wall and thicken of vessels; 21 cases with blood vessel stenosis; 15 cases of 48 lesions with atheromatous spot mass. <b<conclusions</b< the multi-slice CT Virtual Intravascular endoscopy was a valid method to diagnose arteriosclerosises, which was very rapid and noninvasive.
