| 目的 回顾性分析小脑出血的CT、MRI表现及其诊断价值。方法 观察34例小脑出血患者头颅CT、MRI表现,其中31例行CT扫描,21例行MRI扫描。结果 急性期CT表现为小脑半球或小脑蚓部高密度或次高密度团块状病灶。MRI在急性期、亚急性期和慢性期表现出特征性的信号改变。结论 CT能较早发现出血病灶,但有其局限性,MRI能很好地弥补它的缺陷。若使两者相辅相成,结合临床,可进一步提高小脑出血的临床诊断正确率。 |

| Objective It were reviewed that the findings of CT and MRI of cerebellar hemorrhage and the diagnosis value. Methods The findings of CT and MRI were studied in 34 cases with cerebellar hematomas, 31 of them with CT and 21 of them with MRI examination. Results In acute period the findings of CT was the hypertensity area on cerebellar hemispheres or vermis. In subacute period the typical feature of MRI was area of hyperintensity signal on T1WI and T2WI. Conclusion CT scan can find focus of cerebellar hemorrhage earlier than MRI. But it has limitation. MRI can remedy the defect well. Complement the other, we can improve the diagnosis of cerebellar hemorrhage. |
