腔隙梗塞是指脑动脉深穿支及其分支闭塞所造成的脑深部小软化灶,其最大直径不超过20mm。Th-hrim等认为有些腔隙状态是由于小量出血完全吸收的结果,其病灶好发于内囊、丘脑、脑干和基底节,在临床上可以出现各种“腔隙综合征”,本文不包含此类病例。目前的CT扫描尚不能发现直径3mm以下的病灶,由于腔隙梗塞的病灶微小,某些病人临床无特异性症状,当CT扫描呈阴性时,临床上容易漏、误诊,磁共振扫描(MRI)能弥补CT之不足。本文仅对1986年至1989年一组腔隙梗塞病例的CT与MRI作一回顾性比较分析。 1 临床资料 1.1 一般资料共29例,其中男22例,女7例,
Lacunar infarction refers to the deep penetrating branches of the cerebral artery and its branches caused by occlusion of small deep brain softening stove, the maximum diameter of not more than 20mm. Th-hrim, etc. that some of the lacuna state is due to a small amount of bleeding completely absorbed the results of its lesions occur in the internal capsule, thalamus, brainstem and basal ganglia, clinically there may be a variety of “lacunar syndrome” Does not include such cases. At present, the CT scan can not find the lesions below 3mm in diameter. Due to the small infarction size of the lacunar infarction, some patients have no specific clinical symptoms. When the CT scan is negative, it is clinically easy to leak, misdiagnosis, magnetic resonance imaging (MRI) Can make up for the lack of CT. This article only from 1986 to 1989 a group of cases of lacunar CT and MRI for a retrospective analysis. 1 Clinical data 1.1 General Information a total of 29 cases, 22 males and 7 females,
