Description
Usage
Arguments
Value

Description
Calculate the standardized uptake value ratio (SUVR) for all ROIs in the
provided tac data, using the specified reference region. This is an
alternate to suvr() which should provide very similar values.
Usage
1
Arguments
tac
The time-activity curve data from tac_roi()
SUVR_def
a vector of start times for window to be used in SUVR
ref
is a string, e.g. "cerebellum", to specify reference region
...
When called from tm_batch, unused parameters may be supplied
Value
A data.frame of SUVR values for the specified ROIs
#' f <- system.file("extdata", "AD06.tac", package="tacmagic")
fv <- system.file("extdata", "AD06_TAC.voistat", package="tacmagic")
AD06_tac <- load_tac(f, format="PMOD")
AD06_volume <- load_vol(fv, format="voistat")
AD06 <- tac_roi(tac=AD06_tac, volumes=AD06_volume, ROI_def=roi_ham_pib(),
merge=FALSE, PVC=FALSE)
AD06_SUVR <- suvr_auc(AD06, SUVR_def=c(3000,3300,3600), ref="cerebellum")
