Perfusion Weighted Imaging : PWI : basic principles

• Two major approaches 3 techniques – Gadolinium

• DSC : dynamic susceptibility contrast imaging : CBV, CBF, TTM

• DCE : dynamic contrast enhanced imaging : K trans

– No gadolinium

• ASL Arterial Spin Labelling imaging

• Use of perfusion MRI – Study tumor behavior

• Vascular normalisation • Prediction for relapse ?
