Brain magnetic resonance imaging （MRI） of the elderly often reveals white matter changes （WMCs） with substantial variability across individuals. Our study was designed to explore MRI features and site-specific factors of ischemic WMCs. Clinical data of consecutive patients diagnosed with ischemic cerebral vascular disease who had undergone brain MRI were collected and analyzed. Multi-logistic regression analysis comparing patients with mild versus severe WMCs was performed to detect independent associations. Analyses of variance （ANOVAs） were used to detect regionally specific differences in lesions. We found that lesion distribution differed significantly across five cerebral areas, with lesions being predominant in the frontal lobe and parieto-occipital area. To explore WMCs risk factors, after adjusting for gender, diabetes mellitus, and hypertension, only age （P〈0.01）, creatinine （P=0.01）, alkaline phosphatase （ALP）（P=0.01） and low-density lipoprotein cholesterol （LDL-C）（P=0.03） were found to be independently associated with severe WMCs. Age （P〈0.001） was strongly associated with WMCs in the frontal lobe while hypertension was independently related to lesions in the basal ganglia （P=0.048） or infratentorial area （P=0.016）. In conclusion, MRI of WMCs showed that ischemic WMCs occurred mostly in the frontal lobe and parieto-occipital area. The infratentorial area was least affected by WMCs. Typically, age-related WMCs were observed in the frontal lobes, while hypertension-related WMCs tended to occur in the basal ganglia and infratentorial area.
