Alzheimer's disease
- 60-year-old patient presented with memory impairement. There was parietal and hippocampal (MTAS 2) volume loss. While the reduction in volume between the two scan was minimal, it was significant for such a short interval.
- Amyloid PET was postive with loss of supratentorial grey-white differentiation.
- A 30-year-old patient with a family history of Alzheimer's disease presented with cognitive impairment.
- While clearly abnormal for age, the volume loss in the parietal lobes was relatively mild. Hippocampal volume was within normal limits.
- FDG-PET showed marked hypometabolism in the parietal and occipital lobes. The Z-scores on standarised surface projection (Minoshima) maps were between -11 and -13.
