摘　　要：目的:探讨磁共振成像(MRI)和X射线计算机断层扫描成像(CT)对短暂性脑缺血发作(TIA)患者发展至急性脑梗死的诊断价值研究。方法:选取在医院就诊的164例TIA患者,采用随机数表法将其分为对照组和观察组,每组82例。对照组进行CT检查,观察组进行MRI检查,随访26周,比较两组病灶检出阳性率以及治疗后2周病灶情况;观察两组TIA发展至急性脑梗死情况,分析影响TIA发展至急性脑梗死的相关危险因素。结果:观察组缓解期、发作期阳性病灶检出率显著高于对照组,差异有统计学意义(x~2=6.152,x~2=9.426;P<0.05);观察组患者检出的病灶直径及病灶数量均高于对照组,差异有统计学意义(t=5.482,t=3.267;P<0.05);随访期间在35例TIA患者发展至急性脑梗死中,对照组19例,观察组16例,差异无统计学意义。单因素分析年龄、吸烟、饮酒、高血压、高血糖、冠心病、高血脂和胆固醇是TIA发展至急性脑梗死的相关危险因素(x~2=4.364,x~2=5.845,x~2=9.813,x~2=15.915,x~2=12.846,x~2=10.652,x~2=7.567,x~2=9.846;P<0.05);患者年龄、高血压、高血糖均是影响TIA发展至急性脑梗死的独立危险因素(OR=1.132,OR=2.230,OR=1.154,OR=1.324;P<0.05)。结论:MRI、CT均可反映TIA病情进展情况,但MRI检查准确率高于CT检查,可明确病灶位置及数量。Objective: To explore the diagnostic value of magnetic resonance imaging(MRI) and X-ray computed tomography(CT) in patients with transient ischemic attack(TIA) developing to acute cerebral infarction. Methods: 164 patients with TIA who admitted to hospital were selected and were divided into control group and observation group by random number table method, with 82 cases in each group. The control group underwent CT examination, and the observation group underwent MRI examination, and the time of follow up was 26 weeks. The positive rates of detected lesion and the lesion situation of the two weeks after treatment between the two groups were compared. The developments from TIA to acute cerebral infarction in patients of the two groups were observed, and the related risk factors that influenced the development from TIA to acute cerebral infarction were further analyzed. Results: The detection rates of positive lesions in the remission phase and the attack phase of observation group were significantly higher than those of control group(x~2=6.152, x~2=9.426, P<0.05), respectively. The diameter and number of detected lesions in observation group were significantly higher than those in control group, and the difference was statistically significant(t=5.482, t=3.267, P<0.05), respectively. During the follow-up period, there were 19 cases in control group and 16 cases in observation group in 35 patients with TIA developed into acute cerebral infarction, and the difference of that between two groups was not statistically significant. The results of univariate analysis indicated that age, smoking, drinking, hypertension, hyperglycemia, coronary heart disease, hyperlipidemia and cholesterol were related risk factors for the disease that TIA developed to acute cerebral infarction(x~2=4.364, x~2=5.845, x~2=9.813, x~2=15.915, x~2=12.846, x~2=10.652, x~2=7.567, x~2=9.846, P<0.05). And the age, hypertension, hyperglycemia and hyperlipidemia of patients were independent risk factors that affected the development from TIA to acut
