近期皮质下小梗死MRI影像演变及相关因素分析
Analysis of MR imaging evolution and related factors of recent small subcortical infarcts with cerebral small vessel disease
摘要
Abstract
Objective:To explore related factors affecting MRI evolution of recent small subcortical infarct(RSSI).Materials and Methods:A total of 105 patients with RSSI were admitted between August 2019 and September 2024.There were 78 males and 27 females,with mean age(62.77±13.28)years.Clinical information of patients,images data of head MRI were collected.All patients were divided into cavitation group and no cavitation group[white matter hyperintensities(WMH)and disappearance]to analyze related factors affecting evolution with multivariate logistic regression analysis.Results:Sixty-three cases(60.00%)developed to cavities,34 cases(32.38%)evolved into WMH,and 8 cases(7.62%)disappeared.There were significant differences in gender,initial diffusion-weighted imaging(DWI)infarct diameter and number of old lacunes lesion between the two groups(P<0.05).In logistic regression analysis,initial DWI infarct diameter(OR=1.394,P<0.001)and number of old lacunes(OR=1.455,P=0.028)was an independent predictor of cavity formation.Conclusions:About 60%of RSSI develop to cavitation.All infarct lesions were reduced during follow-up.The RSSI showing larger diameter of infarct lesions and more number of old lacunar infarction have a greater possibility of cavitation.关键词
