[99mTc]TRODAT-1 SPECT imaging correlates with odor identification in early Parkinson disease
Dopamine Plasma Membrane Transport Proteins
Tomography, Emission-Computed, Single-Photon
Olfactory function is highly correlated with dopamine transporter imaging abnormalities in early Parkinson disease (PD). Further studies are warranted to determine whether changes over time in these two measures are also correlated in early PD.
