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rKep、rKtrans、rVe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rKep、rKtrans、rVe均低于中危组、低危组(P<0.05).rKep、rKtrans、rVe、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.
Abstract
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 rKep,rKtrans and rVe 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).rKep,rKtrans and rVe in high-risk group were lower than those in medium-risk group and low-risk group(P<0.05).The combined prediction sensitivity of rKep,rKtrans and rVe 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.
