摘　　要：目的探讨无症状脑梗塞(SCI)的临床特征与头颅MRI、MRA、TCD改变。方法对50例病人进行临床分析,并进行头颅MRI、MRA和TCD检测,加以对比分析。结果MRI检出梗塞灶的病人行MRA检查,异常检出率为93.02%,TCD异常检出率为94.87%。结论MRI是确诊SCI重要条件之一,并能清晰、准确显示小脑、脑干梗塞;MRA能显示病变血管;TCD对SCI有早期辅助诊断价值,对治诊及预后有很好指导作用。Objective To investigate the clinical features of silent cerebral infarction (SCI) and the relative changes of brain MRI and TCD examination. Methods Clinical review was performed on 50 SCI patients who had underwent brain MRI,MRA and TCD examination and the results were compared and analyzed. Results The patients were examined to be SCI by MRI before receiving MRA and TCD examination. The abnormality rate detected by MRA is 93.0%,and the rate by TCD is 94.8%. Conclusion MRI is one of important methods to diagnose SCI because it can clearly and correctly display cerebellum or brainstem infarction; TCD can assist the early diagnosis of SCI,while MRA can display the pathological changes of blood vessel,which is a good instruction to diagnosis and prognosis of SCI patients.
