According to the most recent edition of the DSM V, neurocognitive disorder (NCD), formerly referred to as dementia, is a debilitating condition that progressively diminishes quality of life. It impacts both physical and cognitive domains, including memory and aberrant behavior. If usual presentation is uncertain, perfusion, functional, and molecular imaging are useful. Gold standard marker for the diagnosis of Alzheimer's disease (AD) is FDG PET imaging. Recent studies have shown promising results, whereby the cerebral blood flow in arterial spin labeling (ASL) of MRI and the hypometabolism FDG PET both show a consistent regional abnormality. Therefore, ASL MRI imaging carries a potential role in assisting diagnosis of neurocognitive disorder.
