低场强MR与CT诊断小脑梗死的影像分析

Analysis of low field MR and CT in the diagnosis of cerebellar infarction image

目的:通过对小脑梗死患者开展MR、CT两种方式的检查,对比低场强MR与CT对小脑梗死的诊断价值。方法:收治小脑梗死患者51例,慢性期32例,在患者发病1个月后开展MR与CT检查;急性期19例,在患者发病24小时内开展CT与MR检查。结果:32例慢性期患者经CT扫描发现病灶12例(37.5%),CT主要表现为邻近边缘清晰的点片状阴影;经MR扫描发现病灶32例(100%),MR主要表现为长T1长T2信号。19例急性期患者经CT扫描发现病灶5例(26.3%),CT主要表现为密集斑点状阴影;经MR扫描发现病灶19例(100%),MR表现主要为稍长T1长T2信号。结论:与CT的诊断结果相比较,MR在小脑梗死的临床诊断中更具有使用价值。

Objective:We conduct MR and CT inspection in cerebellar infarction patients,and then compare the value of low field MR and CT in the diagnosis of cerebellar infarction.Methods:51 cerebellar infarction patients were recruited from January to October in 2011.32 chronic period patients were measured with MR and CT examination 1 months after the onset of the disease,19 acute per iod patients were measured with MR and CT examination within 24 hours after the onset of the disease.Results:In the32 chronic patients,12 cases(37.5%)were detected positive by CT scan,mainly presenting as adjacent edge clear point patchy shadows;32 cases(100%) were detected positive by MR imaging,mainly presenting as long T1 and long T2 signal.In the 19 acute stage patients,5 cases(26.3%) were detected positive by CT scan,mainly presenting as dense punctate shadows;19 cases(100%)were detected positive by MR imaging,mainly presenting as lightly long T1 and T2 signal.Conclusion:Compared with the diagnostic results with CT,MR is more useful in clinical diagnosis of cerebellar infarction.
