摘　　要：目的分析磁共振弥散成像在短暂性脑缺血的临床应用价值。方法选取我院收治的78例短暂性脑缺血患者为研究对象,随机分为对照组和观察组,分别采取CT和磁共振弥散成像(MRI)检查,比较2组阳性率、病灶数及平均直径。结果对照组阳性率为59.0%,观察组为82.1%,差异有统计学意义(P<0.05)。对照组检出34处缺血灶,平均直径(6.33±3.57)mm,观察组可见62处缺血灶,平均直径(9.55±3.41)mm,2组比较差异有统计学意义(P<0.05)。结论相较于CT检查,磁共振弥散成像在明确短暂性脑缺血患者的病变部位、确定缺血范围等方面优势显著,可为疾病的诊断和有效治疗提供有力依据。Objective To analyze the clinical value of MR diffusion-weighted imaging（DWI）in transient ischemia attack（TIA）patients.Methods Seventy-eight TIA cases in our hospital were selected and randomly divided into study group and control group,which were given CT and DWI examination respectively.The positive rate,the number of lesion and the average diameter between the two groups were comparatively analyzed.Results The positive rate of 59.0% in the control group was significantly lower than 82.1%in the study group（P〈0.05）.In addition,34 ischemic lesions were detected in control group while 62 ischemic lesions were detected in study group,which showed statistical difference（P〈0.05）.What＇s more,the control group displayed lesion diameter of（6.33 ± 3.57）mm,which was lower than（9.55 ± 3.41）mm in the study group（P〈0.05）.ConclusionIn terms of the identified diagnosis of lesion location and ischemic range,DWI examination can take an advantage over CT examination.It＇s clear that DWI can provide a strong evidence for the diagnosis and the effective treatment of TIA.
