Note—For copper-pyruvaldehyde-bis(N4-methylthiosemicarbazone) (62Cu-PTSM) and copper-diacetyl-bis(N4-methylthiosemicarbazone) (62Cu-ATSM) studies, standardized uptake values (SUVs) based on total body weight were measured 20 minutes after radiotracer injection. SUVmax = maximum standardized uptake value.
a
2 MBq/kg.
b
5 MBq/kg.
c
3.6 MBq/kg.
d
4.7 MBq/kg.
