Fig. 1From: MRI with ultrahigh field strength and high-performance gradients: challenges and opportunities for clinical neuroimaging at 7 T and beyondComparison of susceptibility-weighted imaging (SWI) using 3-T and 7-T magnetic resonance imaging. Axial SWI images are shown at the level of the basal ganglia in a healthy individual acquired at 3 T (a) and 7 T (b). At higher field strength, the shorter T2* relaxation times result in the greater SWI sensitivity to magnetic susceptibility differences in the blood vessels and mineralization in the basal ganglia, particularly in the globus pallidusBack to article page
