T2 FLAIR高信号血管征在缺血性脑血管病中的发生规律及价值
The Occurrence Regularity and Clincal Values of T2 FLAIR Vasculcar Hyperintensity(FVH) ;Sign in Ischemical Cerebralvascular Disease
摘要
Abstract
Objective:To investigate the occurrence rules and clinical value of T2 Flair vascular hyperintensity(FVH)in ischemic cerebrovascular disease.Method:A retrospective MRI findings were analyzed in 120 cases of clinically diagnosed patients with ischemic cerebrovascular disease,including FVH sign,vascular stenosis,leukoaraiosis(leukoaraiosis,LA)and infarcttion(ASPECT score).The relationship between the FVH sign and stenosis degree and then the LA grade was evaluated using Spearman rank correlation analysis.The incidence rate difference of cerebral FVH sign was assessed by chi square test between different degrees of stenosis (none,mild to moderate stenosis,severe stenosis and occlusion),and leukoaraiosis grade groups(none,grade 1,grade 2,grade 3),whileas different infarction phase(subacute and chronic infarction).Rank sum test was used to compare ASPECT score in the patients with and without FVH sign.Result:In 120 cases of ischemic cerebrovascular disease,the occurrence rate of FVH sign was 60.8%(73/120).FVH sign was increased in patients with subacute cerebral infarction than the ones with chronic infarction(76.6%vs 51.9%,P<0.05).The FVH sign is low positively correlated with the degree of vascular stenosis(r=0.277,P<0.05).The incidence rate of FVH sign was also significantly different(P<0.01)with 44.0%(22/50)for light-moderate stenosis,71.7%(33/46)for severe stenosis and 75.0%(18/24)for occlusion of the involving arteries. Slight positive correlation was also present between FVH sign and the LA grade(r=0.321,P<0.05). FVH sign incidence rate was 50.0%(6/12),42.5%(17/40),62.5%(25/40) and 89.3%(25/28)in none LA,grade 1 LA,grade 2 LA and grade 3 LA(P<0.05).There was no difference in ASPECT scores between patients with and without FVH sign(Z=-0.372,P=0.71).Conclusion:FVH is a common sign of ischemic cerebral vascular disease due to intracranial arterial stenosis,which is indeed related to the phase of cerebral infarction,the stenosis degree of involved artery and microvascular disease.关键词
