Neuromelanin-MRI can detect reductions in volume and intensity of the substantia nigra in Parkinson’s disease (PD). High-resolution magnetization transfer (MT) contrast T1-weighted sequences are used, and the MT pulse is time-consuming. We evaluated the degree of motion during a long (~ 12 min) scan in a PD patient and a healthy volunteer, and the effect of motion correction using a wireless RF-triggered acquisition device (WRAD) developed in our group. Despite only minor motion, for both participants, motion correction improved image quality.
