imgfur - tpcclib 0.7.7 © 2021 by Turku PET Centre

Calculates of Fractional Uptake Rate (FUR) or FUR-based Metabolic Rate (MR)
image from static or dynamic PET image in ECAT 6.3 or 7.2, NIfTI, or
Analyze 7.5 format. Information on FUR in:
http://www.turkupetcentre.net/petanalysis/model_fur.html
 
Usage: imgfur [Options] inputfile image starttime endtime furimage
 
FUR calculation start and stop time must be entered in minutes;
set both to zero to use the whole time range from image data.
 
Options:
 -Ca=<value>
     Concentration of native substrate in arterial plasma (mM),
     for example plasma glucose in [18F]FDG studies.
     With this option the metabolic rate (umol/(min*100 g)) is calculated.
 -LC=<value>
     Lumped Constant in MR calculation; default is 1.0.
 -density=<value>
     Tissue density in MR calculation; default is 1.0 g/ml.
 -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. Calculation of FUR image from a dynamic image from 45 to 60 min:
     imgfur ua2918ap.kbq ua2918dy1.v 45 60 ua2918fur.v
 
Example 2. Calculation of glucose uptake image, when tissue density is 1.04,
plasma glucose concentration is 5.2 mM, lumped constant is 0.52, from
a static (one frame) image:
     imgfur -density=1.04 -Ca=5.2 -LC=0.52 a864ap.kbq a864dy1.v 0 0 a864mrglu.v
 
The unit of pixel values in the FUR image is
(mL plasma)/(min*(mL tissue)) by default, and umol/(min*100 g) in metabolic
rate image.
