Parameters Characterizing Dispersion Function of Tracer in Blood, from Vena Cava to Blood Counter Sampling Point in Femoral Artery

Parametera (-)b (-)τ1 (s)τ2 (s)

  • n = 4. Values represent mean and SD over 4 rats. For each animal, parameters were determined by fitting dispersion-corrected image-derived vena cava input function to arterial input function measured with external microvolumetric blood counter.

  • (-) = values are dimensionless.
