磁共振和彩色多普勒超声对单纯颈动脉斑块的检测效果对比研究

A comparative study between MRI and color doppler ultrasound in detecting for the effect of statin in the treatment of simple carotid artery plaque

目的比较核磁共振成像(MRI)和彩色多普勒超声检测单纯颈动脉斑块的效果。方法选取单纯颈动脉斑块患者60例作为研究对象,随机分为对照组和他汀组,对2组患者行彩色多普勒超声及MRI检查,治疗6个月后复查彩色多普勒超声和MRI。结果彩色多普勒超声与MRI对不同性质颈动脉斑块检出率比较,差异无统计学意义(P>0.05)。彩色多普勒超声与MRI检查均显示他汀组治疗颈动脉斑块前、后颈动脉斑块检出率比较差异有统计学意义(P<0.05)。1例短暂性脑缺血发作患者MRI提示斑块内出血及坏死脂质核心,彩色多普勒超声仅提示低回声斑块。结论MRI与彩色多普勒超声对不同性质颈动脉斑块的检出率无显著差异,而MRI分析颈动脉斑块成分效果更好。瑞舒伐他汀治疗不稳定稳定颈动脉斑块效果显著。

ObjectiveTo compare the effects of magnetic resonance imaging(MRI)and color Doppler ultrasound on the detection of simple carotid plaque.MethodsSixty patients with simple carotid plaques were selected as subjects and randomly divided into control group and statin group.Color Doppler ultrasound and MRI were performed in 2 groups of patients,and color Doppler ultrasound and MRI were reviewed 6 months after treatment.ResultsThere was no significant difference in the detection rate of carotid plaques with different characteristics by color Doppler ultrasound and MRI(P>0.05).Color Doppler ultrasonography and MRI showed that the detection rate of anterior and posterior carotid plaques in the statin group was statistically significant(P<0.05).In a patient with transient ischemic attack,MRI showed intra-plaque hemorrhage and necrotic lipid core.Color Doppler ultrasound only suggested hypoechoic plaque.ConclusionMRI and color Doppler ultrasound show no significant difference in the detection rate of carotid plaques with different properties,while MRI analysis of carotid plaques is better.Rosuvastatin is effective in treating unstable and stable carotid plaques.
