We have combined structural and diffusion magnetic resonance imaging to investigate the connectivity of the pedunculopontine nucleus (PPN) region in Parkinson's disease and Progressive supranuclear palsy patients. A total of 87 participants were recruited, including 45 patients PD, 12 patients PSP and 30 age-matched controls. Images were acquired using a 3T (Trio Siemens; T1; T2; diffusion 60 directions b-value 1500s/mm) and a 7T (Trio Siemens; T2* 0.6x0.6x0.6mm3).
