FLAIR images are used to assess global cortical atrophy (GCA), vascular white matter hyperintensities and infarctions.
T2-weighted images are used to assess infarctions, in particular lacunar infarctions in the thalamus and basal ganglia, which can be missed on FLAIR images.
T2*-weighted images are necessary to detect microbleeds in amyloid angiopathy. These images can also depict calcifications and iron deposition.
DWI should be considered as a supplemental sequence in young patients or in rapidly progressive neurodegenerative disorders (DD - vasculitis, CJD).
