摘　　要：目的分析MRI检查FLAIR序列HVS对MCA供血区域的诊断价值。方法回顾性分析本院2017年1月至2019年7月收治的45例MCA供血区急性脑梗死患者的临床资料,将MRI检查的诊断结果进行讨论和分析,并分析出院前、后NIHSS评分、mRS评分。结果阴性HVS有17例,阳性HVS有28例。轻度狭窄8例,中度狭窄10例,重度狭窄13例,闭塞14例;阴性HVS组患者NIHSS评分、梗死面积显著高于阳性HVS组,阴性HVS组患者出院30天的mRS评分低于阳性HVS组患者(P<0.05)。结论各位置HVS具有一定意义,通过对患者MRI影像学特征进行分析,并结合其临床特征可有效诊断MCA供血区急性脑梗死。Objective To analyze the diagnostic value of HVS of the FLAIR sequence in the MRI examination for the MCA blood supply area.Method The clinical data of 45 patients with acute cerebral infarction in the MCA blood supply area from January 2017 to July 2019 were retrospectively analyzed,the diagnostic results of MRI examination were discussed and analyzed,and the NIHSS score and mRS score before and after discharge were analyzed.Results There were 17 cases of negative HVS and 28 cases of positive HVS.There were 8 cases of mild stenosis,10 cases of moderate stenosis,13 cases of severe stenosis,and 14 cases of occlusion;the NIHSS score and infarct size of the patients in the negative HVS group were significantly higher than those in the positive HVS group,and the mRS score of the patients in the negative HVS group at 30 days after discharge was lower than that of the positive HVS group(P<0.05).Conclusion HVS at each location has a certain significance,by analyzing the MRI imaging characteristics of patients and combining its clinical characteristics,acute cerebral infarction in the blood supply area of MCA can be effectively diagnosed.
