Dynamic PCARDP Data Processing

PCARDP implements the following features for the dynamic PET data porcessing:

• Calculation of anatomical images representing blood volume (BV) and myocardium (MYO) from the dynamic uptake series. Depending on the tracer, early and late images are averaged, or alternatively a factor analysis can be applied (water only).
• Calculation of time-activity curves (TAC) from the left ventricle (LV), the right ventricle (RV), as well as from different segments of the myocardium.
• Fitting of adequate kinetic models to the TACs to quantify the uptake parameters.
• Calculation of parametric MBF maps (for NH₃ data only).
• Combination of the results to quantify myocardium function in well-defined sectors given by the American Society of Nuclear Cardiology (ASNC) and the American Heart Association (AHA).
• Generation of a normals database from a set of quantification results obtained from healthy volunteers. Patient data can then be compared against the normal database to quantify deviations in terms of z-score values.
