tac_suv: Calculate SUV from TAC
In ropensci/tacmagic: Positron Emission Tomography Time-Activity Curve Analysis

Description Usage Arguments Value See Also Examples

Calculate the standardized uptake value (SUV) time-activity curve from a tac object, the participant's weight, and the tracer dose. The weight must be in kg, and the tracer dose must be specified. The dose is converted to MBq, the tac is converted to kBq/cc, and the final SUV units are thus in g/cc. Aside from the tac object, the remaining parameters should be left NULL if the required data is in the tac object attributes (as can be done with batch_load().

1	tac_suv(tac, dose = NULL, dose_unit = NULL, weight_kg = NULL)

`tac`	time-activity curve object (decay-corrected)
`dose`	the injected tracer dose
`dose_unit`	unit of tracer dose (e.g. "MBq", "kBq", "mCi"...)
`weight_kg`	the participant's weight in kg
