Perfusion - Pharmacokinetics modeling


Quibim extracts different vascular-based imaging biomarkers which are based on the quantitative pharmacokinetic assessment of Dynamic Contrast-Enhanced Magnetic Resonance Images (DCE-MRI). A representative example of a parameters is the vascular permeability. High values usually correspond to malignant changes associated to an increased tumor neoangiogenesis activity and aggressiveness. If proven, this approach can be useful to classify tumor in phenotypes with different biological behaviour.
