Quantitative Myocardial Perfusion with Dynamic Contrast-Enhanced Imaging in MRI and CT: Theoretical Models and Current Implementation

Figure 2

Single arterial inlets are shown with different magnitude scale in different time instance (a) and the respective magnitude-scaled impulse response function (IRF) in the tissue (b). A contrast bolus can be modeled as trains of arterial inlets (c), producing trains of magnitude-scaled IRF in the tissue (d). Deconvolution aims to reconstruct the IRF that fits the relation between the red and green lines in (c) and (d), respectively.
