dtpa_c2s 1.0.1 © 2003,2005 by Turku PET Centre
Converts arterial blood Gd-DTPA concentration curve to SAT-turboFLASH
LV and myocardial (MC) MRI signal intensity curves.
Parameters:
1) Datafile, containing Gd-DTPA concentration in blood
2) Myocardial blood flow F (mL/mL/min)
3) Extravascular extracellular volume fraction Ve (mL/mL)
4) Venous blood volume fraction Vb (%)
5) Delay time (sec)
6) Omega*M0 for LV region
7) Omega*M0 for myocardial region
8) Signal intensity (output) file
Datafile must contain the following columns in this order:
1) Sample time (sec)
2) Gd-DTPA concentration
[N) Myocardial regions are not used]
