Two simple mathematical functions have been applied for estimating myocardial perfusion and fatty acid metabolism from planar, dynamic 123I-para-phenylpentadecanoic acid (123I-pPPA) studies. The first one uses a modified gamma function and the latter one a biexponential fit. The reciprocal of mean transit time is assumed to represent myocardial blood flow and the fast phase (size and half-time) of the biexponential fit primarily accounts for beta oxidation of 123I-pPPA.
