摘　　要：目的探讨利用磁共振弥散加权成像(diffusion-weighted imaging,DWI)结合ADC图在早期脑梗死与短暂性脑缺血发作(transient ischemic attack,TIA)鉴别的临床应用价值。方法回顾性分析选取2019年4月-2020年10月该院经临床最终确诊39例患者资料完整,均于6~72 h行DWI序列和常规MR序列检查,经CT检查排除脑出血患者,治疗恢复CT或MRI随访检查。结果39例患者经临床诊断证实为早期脑梗死35例,短暂性脑缺血发作4例,1例TIA进展为早期脑梗死。35例早期脑梗死患者行静脉溶栓30例,介入(溶)取栓5例,短暂性脑缺血4例临床均给予有效治疗措施。结论DWI序列检出率较高,可作为诊断早期脑梗死与短暂性脑缺血发作的一项重要指标,临床诊断确诊性较高,可为临床治疗方案提供有价值的影像学依据。To explore the clinical application value of using diffusion-weighted imaging(DWI)combined with ADC map in the identification of early cerebral infarction and transient ischemic attack(TIA).Methods Retrospective analysis selected 39 patients with complete clinical diagnosis in the hospital from April 2019 to October 2020.All patients underwent DWI sequence and routine MR sequence examinations between 6 and 72 hours.Patients with cerebral hemorrhage were excluded by CT examination.The treatment resumed CT or MRI follow-up examination.Results 39 patients were clinically diagnosed to be confirmed as early cerebral infarction in 35 cases,transient ischemic attack in 4 cases,1 case of TIA progressed to early cerebral infarction.35 patients with early cerebral infarction received intravenous thrombolysis in 30 cases,interventional(dissolving)thrombus removal in 5 cases,and 4 cases of transient cerebral ischemia.Effective treatment was given clinically.Conclusion The DWI sequence has a high detection rate and can be used as an important indicator for the diagnosis of early cerebral infarction and transient ischemic attack.The clinical diagnosis has a high degree of definitive diagnosis,which can provide valuable imaging evidence for clinical treatment plans.
