Figure 1.

Maps of significant voxels representing regions of hypoperfusion in FTLD patients according to clinical diagnosis, superimposed to reference T1-weighted MRI image. bvFTD: behavioural variant of Frontotemporal Dementia (first row), SD: Semantic Dementia (second row), PNFA: Progressive Non-Fluent Aphasia (third row), PSP: Progressive Supranuclear Palsy (fourth row), and CBD: Corticobasal Degeneration (fifth row) patient subgroups are reported. Statistical threshold, P < 0.001, T ≥ 3.99, minimum cluster size = 50 voxels. Neurological convention: left is on the left side and vice versa.
