Representative T1-weighted MP-RAGE image (left) with color overlay of segmented deep gray matter structures, R2* relaxation rate constant map (center) and quantitative susceptibility map (right) of a 62-years patient with PD (MDS-UPDRS 46; Hoehn & Yahr 2).
<p>High R2* rates and paramagnetic susceptibilities are found in the basal ganglia. Note the improved gray-white matter contrast on the QSM map compared to the R2* map.</p
Regional mean susceptibilities and R2* (±standard deviation).
<p>Asterisks denote significant differences between controls and patients with Parkinson’s disease (*p<0.05; **p<0.01; ***p< = 0.001).</p
