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(More)
In order to evaluate the influence of physical and instrumental limitations of the PET technique on metabolic data, various parameters have been tested. The measurements were done with a whole body PET scanner PC4096-15WB. The dependence on the transaxial resolution of reconstruction filter cut off frequency αc was investigated. The high resolution (4.8 mm(More)
