Abstract
Prior work has shown that adiabatic T1ρ and T2ρ relaxation time constants may have sensitivity to cellular changes and the presence of iron, respectively, in Parkinson’s disease (PD). Further understanding of these magnetic resonance imaging (MRI) methods and how they relate to measures of disease severity and progression in PD is needed. Using T1ρ and T2ρ on a 4T MRI scanner, we assessed the substantia nigra (SN) of nine non-demented moderately affected PD and ten gender- and age-matched control participants. When compared to controls, the SN of PD subjects had increased T1ρ and reduced T2ρ. We also found a significant correlation between asymmetric motor features and asymmetry based on T1ρ. This study provides additional validation of T1ρ and T2ρ as a means to separate PD from control subjects, and T1ρ may be a useful marker of asymmetry in PD.
