dftsuv - tpcclib 0.8.0 © 2023 by Turku PET Centre
Calculates standardized uptake values (SUV, DUR, DAR) or PID/L from PET
time-activity curves (TAC), injected radioligand dose and subject weight.
SUV is calculated as a mean value between specified sample times, but
optionally TACs can be saved in SUV units.
Information on SUV in:
Usage: dftsuv [Options] tacfile starttime endtime dose weight [resultfile]
-curve=<Filename for SUV curve>
Save regional SUVs from whole measurement time range.
-density=<Tissue density (g/ml)>
Calculate results per tissue mass instead of tissue volume.
Display usage information on standard output and exit.
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.
Suppress displaying normal results on standard output.
Suppress displaying anything except errors.
SUV calculation start and stop time must be entered in minutes;
set both to zero to use the whole time range from TAC data.
Injected dose must be given in units MBq at the time of injection.
Subject weight must be given in kg or liters.
Instead of SUV, the percentage of injected dose per tissue volume
(PID/L, %i.d./L) is calculated, if the subject weight is set to 0 (or below).
TAC file must be correct for physical decay to the injection time.
If the units of radioactivity concentrations and sample times are not
specified inside the TAC file, the units are assumed to be in kBq/mL and min;
units can be specified by adding line(s) to the end of the TAC file,
# unit := Bq/cc
# time_unit := sec
Results are saved in result file format (.res) by default, but if
file name extension is set to .dft, .csv, .dat, or .html, results are saved
in those formats.
