Investigation of the cause of asymptomatic white matter hyperintensities commonly seen on T2 MRI of older patients. Non-invasive radiological methodologies were used, specifically magnetic resonance spectroscopy and perfusion imaging. Results suggested that the majority of these lesions are ischemic in origin. Cognitive function in these patients is being evaluated.

无症状白质高信号的病因调查 常见于老年患者的 T2 MRI。 非侵入性放射学 使用了方法学，特别是磁共振波谱法和 灌注成像。 结果表明，大多数病变 起源于缺血。 这些患者的认知功能正在 评价。
