Fig. 2. Regions of interest (ROIs) for quantitative analysis of tissue contrast in neuromelanin (NM) sensitive images and susceptibility values in susceptibility maps. (a) ROIs for NM analysis. Red and orange circles were drawn for substantia nigra and reference areas, respectively. (b)~(d) ROIs for susceptibility analysis. CN, caudate nucleus; PUT, putamen; GP, globus pallidus; RN, red nucleus; SN, substantia nigra; DN, dentate nucleus
