| 摘 要： | 目的：探讨16层螺旋CT血管造影（CTA）诊断颈动脉狭窄的准确性及应用价值。方法：对30例经颈动脉多普勒超声筛选的颈动脉狭窄及闭塞患者进行CTA检查,对比剂总剂量为100～150ml,注射速率为4.5ml/s,采用对比剂智能团注跟踪技术,进行增强扫描并准确控制延迟时间。比较CTA和脑血管造影（DSA）检查结果。结果：本组30例患者共检测60支颈动脉,其中正常血管18支,狭窄血管42支。CT血管造影能较好地显示血管腔内粥样硬化斑块,依靠CT值可区分钙化斑块、纤维斑块及软斑块,钙化斑块的CT测量值为（490±112）HU,纤维斑块（48±19）HU,软斑块（7±28）HU。结论：CTA检查不仅可判断颈动脉狭窄程度,且能更直观、确切的评价粥样硬化斑块,可取代DSA在颈动脉狭窄诊断中的地位。

| Abstract: | Objective:To investigate the accuracy and application of 16-slice spiral CT angiography(CTA) in the diagnosis of carotid artery stenosis.Methods:Totally 30 patients screened by Doppler ultrasound were examined by CTA or digital subtraction angiography(DSA) and the results were analyzed.Results:The number of normal carotid artery was 18 and the number of stenosis was 42.Conclusion:CTA not only has higher accuracy and visuality for the examination of carotid artery stenosis,but also has better ability to disc... |
