小脑梗死磁共振成像的诊断价值

Diagnostic value of magnetic resonance imaging in cerebellar infarction

目的探讨磁共振成像(MRI)在小脑梗死中的诊断价值。方法分析25例脑干梗死患者的临床及MRI影像学资料,所有患者行常规T1WI、T2WI及液体衰减反转恢复(FLAIR)扫描,14例急性期病例行弥散加权成像(DWI)扫描。结果25例患者中,超急性期4例,急性期13例,亚急性期6例,慢性期2例;小脑右侧半球梗死6例,左侧半球梗死3例,双侧半球梗死2例,小脑中脚梗死4例,小脑半球并小脑蚓部梗死3例,小脑梗死并脑干梗死2例。结论MRI能清晰显示小脑梗死,是诊断小脑梗死的最佳影像学方法。

Objective To investigate the diagnosticvalue of magnetic resonance imaging （MRI） in of eerebellar infarction. Methods The clinical and MRI dala of 25 patients with cerebellar infarction were evaluated retrospectively. All eases were examined with TIWI, T2WI and fluid attenuated inversion recovery （FLAIR） sequences, 14 cases in acute stage were examined with diffusion-weighted imaging （DWI） sequences. Results There were 4 eases in super acute stage, 13 cases in acute stage, 6 cases in subacute stage, 2 cases in chronic stage in these 25 cases according to the time; there were 6 cases with fight eerebellar infarftion, 3 cases with left eerebellar infarction, 2 cases with bihemispherie cerebellar infaretion, 4 cases with middle cerebellar peduncle infarction, 3 cases with cerebellar hemisphere and vermis cerebelli infarction, 2 cases of eerebellar hemisphere and brainstem infaretion. Conclusion Cerebellar infarction can be clearly showed on MRI. MR is the optimal imaging technique in diagnosis of cerebellar infaretion.
