Motor associations of iron accumulation in deep grey matter nuclei in Parkinson's disease : A cross-sectional study of iron-related magnetic resonance imaging susceptibility
Background and purpose: To determine whether iron deposition in deep brain nuclei assessed using high-pass filtered phase imaging plays a role in motor disease severity in Parkinson's disease (PD). Methods: Seventy patients with mild to moderate PD and 20 age- and gender-matched healthy volunteers (HVs) underwent susceptibility-weighted imaging on a 3 T magnetic resonance imaging scanner. Phase sh
