Intravoxel incoherent
motion (IVIM) MRI measures the combined effect of perfusion in the capillaries
and water diffusion in the extracellular extravascular space. However,
verification of the accuracy of IVIM is not performed routinely as it requires
a flow phantom and a pump with accurate and constant output. Our goal is to
develop a practical IVIM quality assurance method based on a simple and compact
flow phantom driven by a power injector. We have demonstrated that using a
simple phantom and a power injector as standard is feasible and can be easily
implemented on many clinical/research scanners
