Cortical thickness (AD signature)
Cortical thickness for the Alzheimer's disease signature

Cortical thickness for the AD signature is the mean of the thickness (in mm) of the following cortical regions from the two hemispheres: middle temporal and inferior temporal, entorhinal, temporal pole, fusiform, superior frontal, rostral and caudal middle frontal, superior and inferior parietal, supramarginal, and precuneus. When the measurement of the thickness of a region in one of the two hemispheres is rejected during quality checks, then only the thickness of a region in one of the two hemispheres is used.
