Abstract

Background: Extracellular free water (FW) has important roles in the occurrence and development of white matter hyperintensity (WMH).

Purpose: To explore the correlations between FW and WMH burden.

Material and methods: A prospective analysis was conducted using magnetic resonance imaging (MRI) data from 126 individuals. WMH burden was determined based on WMH volumes and Fazekas scores from deep and periventricular white matter hyperintensity (DWMH and PWMH, respectively) in fluid-attenuated inversion recovery (FLAIR) images. FW values were taken from diffusion tensor imaging (DTI).

Results: Univariate analysis showed that FW values were correlated with WMH burden, including WMH volumes and DWMH and PWMH Fazekas scores (P < 0.05). After multivariate analysis, FW values were correlated with WMH volumes and DWMH and PWMH Fazekas scores when adjusted for age and hypertension (P < 0.05).

Conclusion: Using MRI, increasing extracellular FW was related to WMH burden.

细胞外游离水的增加与白质高密度负荷有关。

背景：目的：探讨细胞外游离水（FW）与白质高密度（WMH）之间的相关性：利用 126 人的磁共振成像（MRI）数据进行了前瞻性分析。WMH负荷是根据液体减弱反转恢复（FLAIR）图像中深部和脑室周围白质高密度（分别为DWMH和PWMH）的WMH体积和Fazekas评分确定的。FW值来自扩散张量成像（DTI）：单变量分析表明，FW值与WMH负荷相关，包括WMH体积、DWMH和PWMH Fazekas评分（P P 结论：细胞外FW值的增加与WMH负荷有关：通过磁共振成像，细胞外FW的增加与WMH负荷有关。
