tac |
The time-activity curve data from tac_roi() |
SUVR_def |
a vector of start times for window to be used in SUVR |
ref |
a string, e.g. "cerebellum", to specify reference region |
... |
When called from tm_batch, unused parameters may be supplied |
A data.frame of SUVR values for the specified ROIs
