Brain perfusion SPECT correlates with CSF biomarkers in Alzheimer’s disease

Purpose Our aim was to study the correlations between cerebrospinal fluid (CSF) biomarker levels such as β-amyloid 42 (Aβ42), total and phosphorylated tau protein (T-tau and P-tau) and brain perfusion SPECT in Alzheimer’s disease (AD) using a voxel-based methodology.
