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.
suvr_auc(tac, SUVR_def, ref, ...)The time-activity curve data from tac_roi()
a vector of start times for window to be used in SUVR
is 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 #' 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")
