【摘要】目的 探讨64排螺旋CT对锁骨下动脉狭窄疾病的应用及诊断价值.方法 对临床怀疑锁骨下动脉狭窄患者8例进行64排CTA锁骨下动脉增强扫描,将获得的数据进行容积再现(VR)、多平面重建(MPR)、最大密度投影(MIP)、曲面重建(CPR),分析锁骨下动脉狭窄的部位及程度.结果 8例均获得清晰影像,锁骨下动脉均显示中重度狭窄,其中左侧5例,右侧3例;6例为单侧近端狭窄,2例为单侧近段和中段狭窄;有软斑块3例,硬斑块5例.结论 64排螺旋CT血管造影能快速、准确、清晰、无创地显示锁骨下动脉狭窄并评价狭窄性质、范围和程度,为临床进一步治疗提供重要信息.%Objective To estimate the value of 64-siicc CTA for the diagnosis of subclavian artcry(SA) stenosis. Methods 8 patients with subclavian artery stenosis were examined by CTA using 64-slicc CT scanner. The source images were post processed u-sing volume rcndcring( VR) , multiple planar reformation (MPR) , maximum intensity projcction(MIP) and curved planar reformation (CPR) , and the observation and analysis was made on the location and degree of SA stenosis. Results CTA was successfully done in all cases,and CTA showed medial SA stenosis in all cases. The lesions involved left in 5 cases and right in 3 cases. The proximal segments of subclavian artery involved in 6 cases,the proximal and middle segments of subclavian artery involved
