摘　　要：目的探讨颈动脉超声与头颅MRI在老年无症状性脑梗死(SBI)检查中的价值。方法选取我院门诊部体检中心体检者88例,均进行颈动脉超声、头颅MRI及血脂的测定。结果 88例体检者中,采用头颅MRI共检出脑梗死病变50例,占总例数56.82%。颈动脉超声检出一侧以上颈动脉内膜中层增厚(IMT)或斑块形成者72例,其中45例同时合并脑梗死,占颈动脉超声异常的62.50%。头颅MRI诊断脑梗死阳性与阴性之间进行比较,颈动脉IMT差异有统计学意义(P<0.05)。结论头颅MRI是一种早期发现无症状脑梗死无创、可靠的检查和诊断方法,凡颈动脉超声提示异常者,无论血脂异常与否,均有必要行头颅MRI检查进一步明确诊断。Objective To analyze carotid artery sonography and brain magnetic resonance imaging （MRI） findings in symptomless brain infarction in the elderly. Methods A. total of 88 examinees in the outpatient were enrolled in the study, and underwent carotid artery sonography and brain MRI, as well as blood lipid determination. Results Brain infarctions were found in 50 patients, accounting for 56.82% of the total number. Of the 88 studied subjects, 72 ones had carotid artery intima media thickness （IMT） or carotid artery plaques, meanwhile, 45 of the 72 cases had brain infarction, accounting for 62.50% of carotid artery lesions. According to MRI diagnosis for symptomless brain infarction, the 88 cases were divided into two groups： positive and negative. Only carotid artery IMT was of significant difference between the two groups （ P 〈 0.05 ）. Conclusion Brain MRI is a noninvasive and reliable screening diagnostic method, especially to elderly symptomless brain infarction. Whether the lipid level is abnormal or not, it is necessary to conduct further brain MRI as a screening for symptomless brain infarction.
