Diagnosis (SD=semantic dementia, bvFTD=behavioural variant frontotemporal dementia, AD=Alzheimer’s disease, LBD=Lewy body dementia, CBD=corticobasal degeneration). 1st dose represents the normal dose scan, in MBq. 2nd dose represents the low-dose/ultra-low-dose scan, also in MBq. The ULD controls were scanned on a separate scanner, as described in the methods section. Note the absence of control no. 9, (n=22).
