摘　　要：目的:探讨高分辨磁共振成像联合弥散加权成像对颈动脉易损斑块识别、诊断价值。方法:选择庆云县人民医院经颈动脉造影和病理检查确诊为颈动脉斑块的136例患者作为研究对象(2021年1月~2023年1月)。两组患者均在颈动脉造影、病理检查和治疗前完成高分辨磁共振成像、弥散加权成像检查,分析两者联合应用对颈动脉易损斑块和斑块成分的识别效果。结果:与颈动脉造影和病理检查确诊结果相比,联合诊断对稳定斑块诊断符合率(96.83%,61/63)、易损斑块诊断符合率(97.37%,74/76)和总符合率(97.12%,135/139)显著高于高分辨磁共振成像和弥散加权成像(P<0.05)。结论:两种成像方式单独应用,对颈动脉易损斑块识别能力欠佳,联合应用可大幅度提升鉴别诊断准确性,并可明确斑块成分,可为临床诊断与治疗提供更加准确、全面的参考资料。Objective:To explore the value of high resolution magnetic resonance imaging(HRMRI)combined with diffusion weighted imaging(DWI)in the identification and diagnosis of vulnerable carotid plaque.Methods:136 patients with carotid plaque confirmed by carotid angiography and pathology in Qingyun County People’s Hospital were selected as the study subjects(January 2021 to January 2023).Both groups of patients completed high-resolution magnetic resonance imaging and diffusion weighted imaging before carotid angiography,pathological examination and treatment,and analyzed the recognition effect of the combination of the two on vulnerable plaque and plaque components of the carotid artery.Results:Compared with the results of carotid angiography and pathological examination,the coincidence rate of combined diagnosis for stable plaque(96.83%,61/63),vulnerable plaque(97.37%,74/76)and total coincidence rate(97.12%,135/139)were significantly higher than those of high-resolution magnetic resonance imaging and diffusion weighted imaging(P<0.05).Conclusion:The two imaging methods used alone have poor recognition ability for vulnerable plaque of carotid artery.The combined application can greatly improve the accuracy of differential diagnosis and clarify the plaque components,which can provide more accurate and comprehensive reference data for clinical diagnosis and treatment.
