Visualization of average saliency maps of patients with parkinsonian diseases.

Caption

Visualization of average saliency maps of patients with idiopathic Parkinson’s disease (IPD), multiple system atrophy (MSA) and progressive supranuclear palsy (PSP) in the training cohort showing characteristic regions contributing to the deep metabolic imaging (DMI) indices. The color corresponds to the importance score indicating the contribution of a region for the generated the deep metabolic imaging (DMI) indices. The color directions (yellow and red vs. cyan and blue) represent different influences on the DMI indices (increased uptake value contributes to the increase or decrease of the probability of IPD, MSA, or PSP in the DMI indices). The arrows pointed to the most salient brain regions including 1: Cerebellum, 2: Midbrain, 3: Putamen, 4: Thalamus.
