低场强MR与CT诊断小脑梗塞的影像分析

The low field MRI and CT imagines for cerebellum infarction diagnosing

目的评价低场强ＭＲ与ＣＴ扫描诊断小脑梗塞的价值。材料与方法本组５９例病人分为两组；急性期２１例，发病２４小时内行ＣＴ、ＭＲ检查。慢性期３８例，发病一月后行ＭＲ、ＣＴ检查；结果急性期２１例，ＣＴ发现病灶６例约占２８．５％表现为斑点状低密度阴影，ＭＲ扫描２１例均发现病灶，其表现为等Ｔ１或稍长Ｔ１长Ｔ２信号。慢性期３８例，ＣＴ发现病变１７例约占４４．２％，表现为边缘清楚的点片状低密度阴影，３８例ＭＲ均表现为长Ｔ１、长Ｔ２高信号。结论小脑梗塞性病变ＭＲ检查优于ＣＴ检查。

Purposes To eveluate the diagnositc value in low field MR imagine and CT imagine for cerebellum infarction Ma terials and methods 59 patients were divided into two groups. The md group,21 patients in urgent,performed CT,MR inspection within 24 hours. The second group, 38 patients in chronic. performed CT, MR inspection one month later after the patients got the disease. Results For the first group,6 patients 28. 5% of 21 cases,have found lesions on their CT imagines appearing as equal T1 or a little longer T1 and long T2. For second group, 17 patients,44. 2% of cases,there have low density spot like slice shadow with sharp margin on their CT imagines.The T1 is long and low,and T2 is high onr MR imagines for all patients in the group. Conclusion MR is bettler than CT in the lesion of cerebellum infarction.
