We are engaged in PET imaging for oxidative stress using 64Cu-ATSM, instead of 62Cu-ATSM, combined with PET imaging with 11C-PiB and 18F-MK-6240 for amyloid-β and tau protein, respectively, in patients with Alzheimer’s disease. The gene discussed is MAPT; the disease is early-onset autosomal dominant Alzheimer disease.
