{|
|
PkModeling (Pharmacokinetics Modeling) calculates quantitative parameters from Dynamic Contrast Enhanced DCE-MRI images. This module performs two operations:
# Converts signal intensities to concentration values. The concentration values are used to calculate quantitative parameters.
# Calculates quantitative parameters from concentration values. These parameters include:
;Ktrans: Volume transfer constant between blood plasma and EES (extracellular-extravascular space) at each voxel
;Ve: Fractional volume for extracellular space at each voxel
;MaxSlope: Maximum slope in the time series curve of each voxel
;AUC: Area under the curve of each voxel, measured from bolus arrival time to the end time of interval, normalized by the AUC of the AIF
