摘　　要：目的探讨ABCD评分结合磁共振弥散加权成像（DwI）对短暂性脑缺血发作（1rIA）后7d内发生脑梗死的临床评估价值。方法按照ABCD评分标准，同时收集DWI的检查结果，对105例TIA患者的临床资料进行分析。结果22例ABCD评分〈3分的TIA患者中无一例发生脑梗死，83例ABCD评分≥3分的TIA患者中发生脑梗死24例（28．9％），且ABCD评分越高，脑梗死发生率越高（P〈0．01）。DWI异常者42例，发生脑梗死9例（21．4％），DWI正常者50例，发生脑梗死2例（4．O％），两者比较差异有统计学意义（P〈0．05）。结论ABCD评分是临床预测TIA短期发展为脑梗死的有效方法．结合DWI更能提高其临床评估价值。Objective To investigate the clinical value of ABCD score combined with diffuse weighing imaging（ DWI ）for the estimation of transient ischemic attack （TIA） advancing to cerebral infarction in 7 days. Method The clinical data including ABCD score and DWI of 105 cases with TIA were analyzed. Results None of TIA patients with ABCD scores 〈 3 advanced to cerebral infarction. There were 83 cases with ABCD scores ≥3, among whom 24 cases （28.9%）advanced to cerebral infarction. The higher ABCD scores, the higher incidence of cerebral infarction （P 〈 0.01 ）. Nine of 42 cases （21.4% ） with DWI abnormal advanced to cerebral infarction, while 2 of 50 cases （4.0%）with normal DWI advanced to cerebral infarction （P 〈 0.05 ）. Conclusion ABCD score is an effective method for the estimation of TIA advancing to cerebral infarction, and when combined with DWI it is more efficient.
