Figure 1From: Subcortical hyperintensity volumetrics in Alzheimer’s disease and normal elderly in the Sunnybrook Dementia Study: correlations with atrophy, executive function, mental processing speed, and verbal memory Partial regression plots illustrating the relationships in Alzheimer’s disease patients between atrophy measured by brain parenchymal fraction (BPF) and periventricular subcortical hyperintensity (pvSH) volume (top), and between atrophy measured by ventricular cerebrospinal fluid (vCSF) volume and subcortical hyperintensity (SH) volume (bottom).
