摘　　要：目的分析磁共振灌注成像(MR-PWI)联合ABCD2评分预测短暂性脑缺血发作(TIA)后7 d内发生脑梗死风险的价值。方法 TIA患者113例,分别进行MR-PWI检查和ABCD2评分,分析MR-PWI检查结果、ABCD2评分与TIA后7 d内脑梗死发生率的关系。结果 113例患者TIA后7 d内发生脑梗死36例,发生率为31.86%。113例患者ABCD2评分结果为低危64例,中危33例,高危16例,TIA后7 d内脑梗死发生率分别为10.93%、51.52%、75.00%,其发生率呈低危组<中危组<高危组(P<0.05)。ABCD2评分与TIA后7 d内脑梗死发生率呈正相关关系(P<0.05)。MR-PWI检查正常组73例、异常组40例,TIA后7 d内脑梗死发生率分别为16.44%、60.00%,正常组脑梗死发生率明显低于异常组(P<0.05)。MR-PWI异常且ABCD2≥4分组脑梗死发生率明显高于MR-PWI正常且ABCD2<4分组、MR-PWI异常且ABCD2<4分组(P<0.05)。结论 MR-PWI联合ABCD2评分对预测TIA后早期脑梗死发生风险有重要的价值。Objective To investigate the prognostic value of magnetic resonance perfusion weight imaging（ MR-PWI） combined with ABCD2 score in evaluating the risk of cerebral infarction 7 days after the onset of a transient ischemic attack（ TIA）. Methods MR-PWI and ABCD2 score were used in 113 TIA patients to analyze the relationship of MR-PWI test result and ABCD2 score with the incidence of cerebral infarction within 7 days after TIA. Results Thirty-six cases among 113 suffered cerebral infarction within 7 days after TIA onset,and the incidence of cerebral infarction was 31.86%.Of these 113 patients,the ABCD2 score indicated that 64 cases of low-risk,33 cases of moderate-risk and 16 cases of high-risk,respectively. The incidences of cerebral infarction within 7 days after TIA onset were 10.93%,51.52% and 75.00% in the low-,moderate-and high-risk groups,respectively,which presented as a trend of low-risk group 〈middle-risk group〈 high-risk group（P〈0.05）.The MR-PWI detection showed that the incidences of cerebral infarction were 16.44% and 60.00% in the normal group（ 73 cases） and abnormal group（ 40 cases） within 7 days after TIA onset,respectively. The incidence of normal group was significantly lower than that of abnormal group（ P〈0.05）. Compared to the group of normal MR-PWI and ABCD2 score〈 4,the group of abnormal MR-PWI and ABCD2 score 4,the incidence of cerebral infarction in the group of abnormal MR-PWI and ABCD2 score ≥4 group increased significantly（ P〈0. 05）. Conclusion The combination of MR-PWI with ABCD2 score is valuable in predicting the risk of cerebral infarction after TIA.
