声脉冲辐射力成像技术在冠心病伴颈动脉粥样软斑诊断中的应用价值

Application Value of Acoustic Radiation Force Impulse in Diagnosis of Coronary Heart Disease Complicated With Carotid Atherosclerosis Soft Plaques

目的探讨声脉冲辐射力成像(ARFI)对冠心病伴颈动脉粥样软斑的诊断价值。方法选取在我院进行治疗的冠心病伴斑块患者150例,用ARFI对所选患者的斑块性质进行鉴定,观察软斑、硬斑、混合斑块的例数,比较ARFI与超声造影技术检测结果的准确性。结果 ARFI诊断患者颈动脉斑块为软斑块90例,硬斑块35例,混合斑块25例;超声造影技术检测出软斑65例。两种检测方法进行比较,检测结果差异有统计学意义(P<0.01)。结论 ARFI可以鉴定斑块的性质;ARFI测定软斑的准确性高于超声造影;ARFI的应用可以预防急性冠脉综合征的发生。

Objective To explore the diagnostic value of acoustic radiation force impulse （ARFI） in coronary heart disease （CHD） complicated with carotid atherosclerosis soft plaques. Methods ARFI was used to detect 150 CHD patients complicated with plaques in our hospital for identification of plaque nature and observation of cases of soft plaques, hard plaques and mixed plaques. ARFI detection results were compared with contrast-enhanced ultrasound （CEUS） for accuracy. Results ARFI detected 90 cases of soft plaques, 35 cases of hard plaques and 25 cases of mixed plaques, CEUS detected 65 cases of soft plaques, with statistically significant difference （P 〈0.01）. Conclusions ARFI can identify the nature of plaque; ARFI has higher accuracy than CEUS in the detection of soft plaques; the application of ARFI can prevent the occurrence of acute coronary syndrome.
