Quantitative Susceptibility Maps w/in Thalamus, Caudate, Globus Pallidus, & Putamen (2 of 3) (IMAGE) Radiological Society of North America Caption Image shows voxelwise analysis of quantitative susceptibility maps within thalamus, caudate, globus pallidus, and putamen comparing participants with secondary progressive (SP) multiple sclerosis (MS) with participants with relapsing-remitting (RR) MS. Areas of higher susceptibility in participants with SPMS compared with participants with RRMS are shown in red-yellow. Areas of lower susceptibility in participants with SPMS compared with participants with RRMS are shown in blue-light blue.
