In SUV values from PET scans, are both the activity concentration in the image and injected activity decay corrected to time of injection?

I found an equation that reads: SUV(t) = Activity concentration (t) / (Injected activity / Body weight ), which implies that the activity concentration is not decay corrected, is this true?

Does the PET scanner software correct for the positron branching ratio of of non-conventional nuclides such as 64Cu and 89Zr to calculate SUV values?

I do not have experience working with PET scanners for patients so I don't know if the software automatically corrects for the branching ratio of the nuclide. Most of the conventional nuclides...
