For optimization and validation of new dynamic contrast-enhanced MRI sequences, a simple and cheap perfusion phantom is developed. Contrast agent is injected via a hose into a sponge and is washed out by a constant water flow. The phantom can be quantitatively described using a gamma-variate function, providing heterogeneous parameter maps. The phantom experiment is relatively well reproducible.
