Perfusion Models Introduction

At the basis of each model there is a simple and intuitive formulation made by Fick:

arterial concentration

tissue concentration

venous concentration

BF

BF

in

out

c

(t)

v

Since the outflow from tissue to the venous system is of less clinical interest, it is normally not investigated. It is relatively safe to assume BF in = BF out = BF
