Patient example. Sixty-five-year-old women with clinical and imaging-based diagnosis of corticobasal degeneration. Relative FDG uptake was severely impaired in the left frontal regions (red arrows). Additionally, there was some degree of relative bilateral uptake deficiency in parietal areas which was more pronounced in PETDixon but also apparent in PETBoneDixon as compared to PETCTderived (white arrows), resulting in an imaging diagnosis of Alzheimer’s disease in PETPseudoCT/BoneDixon for reader 1 and in PETDixon/PseudoCT/BoneDixon for reader 2. Note: readers were blinded to the clinical diagnosis
