高频彩超与多层螺旋CT诊断颈动脉粥样硬化斑块的对照分析

Study the High Frequency Color Doppler Ultrasound and Multislice Spiral CT in the Diagnosis of Carotid Atherosclerotic Plaque

目的:探讨高频彩超与多层螺旋CT诊断颈动脉粥样硬化斑块的临床价值。方法:以2017年1月—12月广东省台山市人民医院60例脑梗死患者为研究对象,全部患者均分别以高频彩超和多层螺旋CT检查双侧颈动脉,观察两种诊断方法下患者双侧颈动脉粥样硬化斑块及狭窄的检出情况。结果:高频彩超与多层螺旋CT诊断颈动脉粥样硬化斑块检出率及管腔狭窄度几乎完全一致(κ=0.904,P<0.05;κ=0.957,P<0.05)。结论:高频彩超与多层螺旋CT诊断颈动脉粥样硬化斑块一致性较好,联合应用对颈动脉粥样硬化斑块性质进行评定可提高不稳定斑块检出率,强化临床诊断效果。

Objective： To investigate the clinical value of high-frequency color Doppler ultrasound and multislice spiral CT in the diagnosis of carotid atherosclerotic plaque. Methods： 60 patients with cerebral infarction in our hospital from Jan. to Dec. 2017 were selected as the study subjects. All patients were examined with high-frequency color Doppler ultrasonography and multi-slice spiral CT. Then the two carotid arteries were examined, and the carotid atherosclerotic plaques and stenosis were detected. Results： The detection rate of the carotid atherosclerotic plaques and the stenosis degree of the carotid atherosclerotic plaques were almost identical with the high-frequency color Doppler ultrasound and multi-slice spiral CT（κ=0.904, P〈0.05;κ=0.957, P〈0.05）. Conclusion： The high-frequency color Doppler ultrasonography and multi-slice spiral CT have great consistency in the diagnosis of carotid atherosclerotic plaque. The combined application of evaluation of the properties of carotid atherosclerotic plaque could improve the detection rate of unstable plaque and strengthen the clinical diagnosis effect.
