摘　　要：目的:探讨磁共振弥散加权成像(MR-DWI)与常规磁共振成像(MRI)在老年短暂性脑缺血发作(TIA)诊断中的应用价值。方法:选取2020年1月~2023年12月本院收治的82例老年TIA患者,所有患者均接受MRI常规序列和MR-DWI序列检查。比较两种方法对TIA阳性检出率、MR-DWI序列检出阳性和阴性患者临床症状及入院7d内脑卒中发生情况的检出率。结果:82例患者经MR-DWI序列检出阳性检出率为62.20%,高于常规MRI阳性检出率的46.34%,差异有统计学意义(P<0.05);MR-DWI序列检出阳性患者的运动障碍、发作次数、症状持续时间及发病至MR-DWI检查时间同MR-DWI序列检出阴性患者比较,差异有统计学意义(P<0.05);入院7d内,82例患者共发生25例脑卒中,其中MR-DWI序列脑卒中检出率为23.17%,高于常规MRI脑卒中检出率7.32%,差异有统计学意义(P<0.05)。结论:MR-DWI较常规MRI准确性高,对老年TIA患者的诊断具有较高临床指导价值。Objective:To evaluate the diagnostic value of magnetic resonance diffusion weighted imaging(MR-DWI)and conventional magnetic resonance imaging(MRI)in elderly patients with transient ischemic attack(TIA).Methods:A total of 82 elderly patients with TIA admitted to our hospital from January 2020 to December 2023 were selected.All patients received routine MRI sequence and MR-DWI sequence examination.The detection rates of TIA positive,MR-DWI positive and negative clinical symptoms and stroke occurrence within 7 days of admission were compared between the two methods.Results:The positive detection rate of 82 patients by MR-DWI sequence was 62.20%,higher than that of conventional MRI 46.34%,the difference was statistically significant(P<0.05).The movement disorder,the number of attacks,the duration of symptoms and the time from onset to MR-DWI examination in patients with positive MR-DWI sequences were significantly different from those with negative MR-DWI sequences(P<0.05).Within 7 days after admission,a total of 25 strokes occurred in 82 patients,among which the detection rate of stroke with MR-DWI sequence was 23.17%,higher than that with conventional MRI(7.32%),with statistical significance(P<0.05).Conclusion:MR-DWI is more accurate than conventional MRI,and has higher clinical value in the diagnosis of elderly patients with TIA.
