静止性脑梗死的高分辨CT表现与影像分类及临床分析

目的 探讨研究静止性脑梗死高分辨CT表现及临床特点.方法 对急性脑卒中患者及健康体格检查中的受检对象进行高分辨螺旋CT检查,以发现陈旧性梗死灶,并询问病史以排除过去有症状性脑卒中,同时进行影像学分类及病因追查.结果 影像学检查分两类:(1)是静止性腔隙性脑梗死,占82.4%;(2)是静止性小梗死,占17.6%.梗死部位...

Silent Cerebral Infarction High Resolution CT Findings,Image Classification and Clinical Analysis

Objective To study high resolution CT findings and the clinical features in static cerebral infarction.Methods To detect the old infarct in acute stroke patients and healthy physical examination with high resolution CT,and take medical history to eliminate previous symptomatic stroke,as while as to make image classification and explore origin of the disease.Results Imaging changes in two categories: One is stationary lacunar infarction accounted for 82.4%;the other is still a small infarct of 17.6%.Multi-infarct area was in the basal ganglia,internal capsule,brain stem and cerebellum.The etiology is mostly hypertension,cerebral arteriosclerosis,diabetes and coronary heart disease,atrial fibrillation.Conclusion The most Silent cerebral infarction was lacunar infarctions.Imaging is considered to determine static cerebral infarction only screening method.Risk factors,that for census and active older people due to treatment or prevention of cerebral infarction,still have significant symptoms of cerebral infarction and has important clinical value.
