摘　　要：目的:分析磁共振动态对比增强扫描(DCE-MRI)定量参数联合ABCD2评分法对短暂性脑缺血发作(TIA)后进展为脑梗死的诊断价值。方法:选取2020年12月—2022年12月在固原市中医医院就诊的100例TIA患者,根据是否进展为脑梗死将其分为观察组(30例进展为脑梗死)与对照组(70例未进展为脑梗死),比较两组DCE-MRI定量参数、ABCD2评分,比较不同ABCD2分层组DCE-MRI定量参数,绘制受试者工作特征曲线分析DCE-MRI定量参数、ABCD2评分对TIA进展为脑梗死的预测价值。结果:观察组rK_(ep)、rK^(trans)、rV_(e)均低于对比组(P<0.05),观察组ABCD2评分高于对比组(P<0.05)。高危组rK_(ep)、rK^(trans)、rVe均低于中危组、低危组(P<0.05)。rK_(ep)、rK^(trans)、rV_(e)、ABCD2评分联合预测的灵敏度(94.16%)高于单一检测(P<0.05)。结论:DCE-MRI定量参数联合ABCD2评分预测可提高TIA进展为脑梗死的预测灵敏度。Objective To analyze the diagnostic value of quantitative parameters of dynamic contrast-enhanced magnetic resonance imaging(DCE-MRI)combined with ABCD2(age,blood pressure,clinical features,duration of symptom,and presence of diabetes)score in the progression of cerebral infarction after transient ischemic attack(TIA).Methods A total of 100 TIA patients treated in Guyuan Traditional Chinese Medicine Hospital from December 2020 to December 2022 were selected and divided into 2 groups according to whether they developed cerebral infarction:observation group(30 cases developed cerebral infarction)and comparison group(70 cases did not develop cerebral infarction).Quantitative parameters of DCE-MRI and ABCD2 scores of the two groups were compared.The DCE-MRI quantitative parameters of different ABCD2 stratified groups were compared,and the predictive value of DCE-MRI quantitative parameters and ABCD2 score for TIA progression to cerebral infarction was analyzed by receiver operator characteristic(ROC)curve.Results The rK_(ep),rK^(trans) and rV_(e) of observation group were lower than those of comparison group(P<0.05),and the ABCD2 score of observation group was higher than that of comparison group(P<0.05).rK_(ep),rK^(trans) and rV_(e) in high-risk group were lower than those in medium-risk group and low-risk group(P<0.05).The combined prediction sensitivity of rK_(ep),rK^(trans) and rV_(e) and ABCD2 scores(94.16%)was higher than that of single detection(P<0.05).Conclusion The combination of DCE-MRI quantitative parameters and ABCD2 score can improve the prediction sensitivity of TIA progression to cerebral infarction.
