Effect of the identification group size and image resolution on the diagnostic performance of metabolic Alzheimer ’s disease-related pattern

ConclusionsWhile small (20 AD/20 CN images) identification cohorts may be adequate in a favorable selection of cases, larger cohorts (at least 30 AD/30 CN images) shall be preferred to overcome possible/random biological differences and improve ADRP ’s diagnostic performance. ADRP’s performance stays stable even when applied to the validation images with a resolution different than the resolution of the identification ones.
