imgsuv - tpcclib 0.8.0 © 2023 by Turku PET Centre
Calculates SUV (standardized uptake value) image from PET image
in ECAT 6.3 and 7.x, NIfTI, or Analyze 7.5 format.
SUV in image pixels is calculated as mean value in specified time range.
Before calculation, make sure that radioactivity concentration units in PET
image header are correct. Analyze and NIfTI images do not contain units,
therefore unit kBq/mL is assumed.
Analyze and NIfTI must be accompanied by SIF.
Image data and injected dose must be decay corrected to the same time
(usually the tracer injection time).
Usage: imgsuv [Options] image starttime endtime dose weight suvimage
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;
If SUV calculation start and end times are set to zero, then no average
over time is calculated, but the (dynamic) PET image is saved
in SUV or %i.d./L units.
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).
