小脑梗塞的MRI诊断

MRI Diagnosis of Cerebellum Infarction

目的：分析小脑梗塞的ＭＲＩ表现，探讨ＭＲＩ对小脑梗塞的诊断价值。材料和方法：回顾性分析了３２例小脑梗塞的ＭＲＩ图像。结果：１小病灶（＜１０ｍｍ）多呈斑点样，远离脑表面，大病灶（＞１０ｍｍ）多呈楔形、近脑表面；２小脑梗塞的ＭＲＩ信号有其特点，且与病程及病灶大小相关。结论：ＭＲＩ对小脑梗塞的诊断优于ＣＴ，结合临床资料可以与其它疾病相鉴别。

urpose:To analyze the MRI indications for cerebellum infarction and discuss the MRI diagnostic value for that disease.Materials and methods:Reviewing and analyzing MRI images of 32 cases of cerebellum infarctions. Results:(1) small focus(<10mm) showed dot-like feature to far away from the cerebellar surface,while large focus(>10mm) showed wedge shape nearer the surface.(2) the MRI signal had its own characteristics possessing strong relalionship with the cousre of the diease and the size of the focus.Conclusion:For cerebellum infarctions,MRI has stronger diagnostic capability than CT. closely in conbination with the clinical datas,the disease can be differentiated from othese.
