Objective To determine whether regional iron levels are associated with endogenous pain‐inhibitory function and whether iron‐sensitive MRI techniques, quantitative magnetic susceptibility (QSM) and R2∗ mapping capture differences in midbrain iron content in the globus pallidus (GP), periaqueductal grey (PAG), and red n...
