Chin J Magn Reson Imaging, 2025, 16(6): 55-59, 65. DOI:10.12015/issn.1674-8034.2025.06.008.


[Abstract] Objective To investigate the volume and distribution characteristics of white matter hyperintensities (WMH) in patients with end-stage renal disease (ESRD) using MRI three dimensional-fluid attenuated inversion recovery (3D-FLAIR), and to determine if specific brain regions are more susceptible to lesion development and to assess the relationship between WMH volume and clinical biochemical markers and cognitive function.Materials and Methods MRI image data and clinical biochemical indices from 81 ESRD patients and 77 healthy controls were collected. CAT12 software was used to analyze 3D-T1WI images to obtain the whole brain volume of each subject. The 3D-FLAIR images were analyzed by Lesion Prediction Algorithm (LPA) in Lesion Segmentation Tool (LST) to obtain the volume and distribution map of WMH. Two-sample t-test and Mann-Whitney U test were used to analyze the differences in cognitive function scores and the severity of WMH (the ratio of WMH to total brain volume) between the two groups. The Liebermeister test in non-parametric mapping (NPM) software was employed to compare the distribution maps between the two groups. After controlling for the effects of age and gender using partial correlation analysis, the correlations between the severity of WMH and both clinical biochemical indicators as well as cognitive function were assessed. Furthermore, the two groups were categorized according to the severity of WMH, and the ROC curve was constructed.Results The cognitive function scores of the ESRD group were significantly lower compared to the control group [Montreal Cognitive Assessment (MoCA): 22.44 ± 5.23 vs. 26.06 ± 3.20, P < 0.001; Mini-Mental State Examination (MMSE): 25.96 ± 3.81 vs. 28.61 ± 1.85, P < 0.001]. The severity of WMH in the ESRD group was significantly higher than in the control group [1.40 (2.60) vs. 0.36 (0.40), P < 0.001]. The proportion of WMH in the ESRD group was also higher (Z: 1.914 to 6.483, P < 0.05). Although WMH severity was not associated with cognitive function (P > 0.05), it was negatively correlated with serum albumin and glomerular filtration rate (r = -0.337, P = 0.002; r = -0.231, P = 0.041). The area under the ROC curve was 0.817 (95% CI: 0.751 to 0.884).Conclusions Periventricular white matter is particularly vulnerable to damage in ESRD patients, which is closely linked to the decline in renal function and serum albumin levels. WMH serves as a significant imaging marker for effectively distinguishing white matter damage in ESRD.
