taccbv - tpcclib 0.8.0 © 2023 by Turku PET Centre
Subtracts the contribution of vascular radioactivity from regional
PET TTACs. Vascular volume fraction Vb can be given as a value that is
common to all regions, or as regional Vb values in a TAC or PAR file,
calculated from a [O-15]CO study or estimated by model fitting.
Usage: taccbv ttacfile btacfile Vb [outputfile]
Options:
-noneg
Negative TAC values are set to 0.
-pv | -tv
Equation Ct=Cpet-Vb*Cb is applied by default or with option -pv;
with option -tv equation Ct=(Cpet-Vb*Cb)/(1-Vb) is applied.
-sim
Simulate the contribution of vascular radioactivity instead of
correcting for it, calculating Cpet from Ct using equations above.
--force
Program does not mind if the time or calibration units
cannot be converted to match, or if TAC names do not match.
-h, --help
Display usage information on standard output and exit.
-v, --version
Display version and compile information on standard output and exit.
-d[n], --debug[=n], --verbose[=n]
Set the level (n) of debugging messages and listings.
-q, --quiet
Suppress displaying normal results on standard output.
-s, --silent
Suppress displaying anything except errors.
Example 1:
taccbv uo372.tac uo372ab.bld 0.045 uo372cbv.tac
Example 2:
taccbv uo372.dft uo372ab.kbq uo372vb.dft uo372cbv.dft
Vb values that are >=1 are assumed to be percentages.
Blood TAC can be given in a separate BTAC file, or as a region id inside
TTAC file. Original TTAC file is modified, if output file is not given.
