摘　　要：目的探讨颈动脉狭窄的影像学对比分析。方法运用Philips-7500型彩超诊断仪,探头频率3.5～8.0MHZ。对64例临床怀疑有颈动脉狭窄患者进行颈动脉彩色多普勒超声、颈动脉头颅核磁(MRA)成像检查,所有患者MRA检查后两周内接受了脑血管造影(DSA)检查。结果以DSA检查结果为金标准,超声诊断颈动脉狭窄的敏感性96.88%,特异性35.71%,MRA诊断颈动脉狭窄的敏感性93.75%,特异性71.43%。结论本研究结果显示超声对斑块的检出率明显高于MRA和DSA,可以看出超声在颈动脉壁的形态改变研究上较MRA和DSA敏感,且超声可对斑块性质作出判断,这是MRA和DSA所无法做到的。Objective To explore contrastive analysis of carotid stenosis imaging.Methods 64 patients with clinically suspected carotid artery stenosis were subject to examination of carotid color doppler ultrasound（Philips-7500 Color Diagnostic Apparatus with Probe Frequency of 3.5-8.0 MHZ） and carotid arteries MRA imaging.All patients were accepted carotid arteriography within two weeks.Results According to the gold standard of carotid arteriography,the sensitivity and specificity of ultrasonic diagnosis were 96.88% and 35.71%,respectively,and those of MR angiography were 93.75% and 71.43%,respectively.Conclusion The results indicates that the plaque detection rate of color Doppler ultrasound was significantly higher than that of MR angiography or carotid arteriography and the sensitivity of morphological changes in carotid artery wall is higher than that of MR angiography or carotid arteriography.
