本文结合35例脑梗塞病人的MRI与X-CT对比资料,讨论了MRI在缺血性脑血管病诊断中的价值。本文结果证明:1.对于脑梗塞的早期诊断方面,MRI比X-CT优越得多;2.MRI可清晰地显示脑干、小脑的梗(?)灶,而X-CT则很困难;3.在准确显示脑梗塞灶的数目方面,MRI比X-CT占有绝对优势;4.对于有明确偏瘫、失语体征的病人,X-CT有时不能显示“责任病灶”,MRI则很容易发现相对应的病灶;5.MRI可显示脑梗塞外周的缺血性“半影区”,而X-CT则不可能。 In this paper, 35 patients with cerebral infarction MRI and X-CT contrast data to discuss the value of MRI in the diagnosis of ischemic cerebrovascular disease. The results of this paper demonstrate that: 1. MRI is superior to X-CT in the early diagnosis of cerebral infarction; 2. MRI can clearly show the stem and cerebellar peduncles, while X-CT is difficult; 3 .In the accurate display of the number of cerebral infarction, MRI has an absolute advantage over X-CT.4. X-CT sometimes can not show “responsible lesion” in patients with definite hemiparesis and aphasia, and MRI can easily find the corresponding 5. MRI can show ischemic “penumbra” of peripheral cerebral infarction, but X-CT is impossible.
