| 目的分析小脑半球脑梗塞的MR 表现,明确诊断,指导临床治疗。方法20 例,行MR 矢、冠、轴位扫
描,部分病例行增强扫描,并行治疗后复查,观察其MRI 表现。结果①由于小脑半球的供血来源不同,可出现小脑
上动脉供血区,小脑前下动脉供血区,及小脑后下动脉供血区脑梗塞,其中后者最常见; ②于MR 矢、冠、轴位像上可
清楚看到病灶的边界; ③MR 上表现为长T1 ,长T2沿血管分布区异常信号,经临床治疗后,复查可见病灶缩小; ④小
脑半球脑梗塞可伴有其他部位脑梗塞。结论MR 对小脑半球脑梗塞的影像表现较CT 优越,观察清楚,诊断明确,
同时可进行临床治疗效果追踪观察。 |

| Purpose Analyzed the MR appearance of infarction of cerebllum ,for dignosis and to directive clinic treatment . Methods 20 cases of the infarction of cerebllum ,examed by MR with axial ,coronal ,and sigital scan. Some of them
with contrast enhancement . After a period of clinical treatment ,followed by MR examination ,in order to observe the effect
of therapy. Results ①Due to different part of the cerebellar blood supply come from different artery distribution ,so the
different location of the cerebllar infarction could be seen. such as ,the part of superior cerebllar artery distribution ,the part
of anterior inferior cerebellar artery blood supply ,the region of posterior inferior cerebellar artery blood supply ,and so on ; ②
the lesion is clearly margin on MR imaging appearance ; ③high signal on T2 and low signal on T1 associated with the blood
supply of artery distribution ; ④besides cerebellar infarction ,there is other part of the brain ischemia. Conclusion For dignosis the infarction of cerebellum ,MR imaging is advantage than CT scan ,and clearly show on MRI. Correct dignosis is not
difficulty. After the clinical treatment ,the effect could be clearly shown on MRI. |
