Mean apparent propagtor MRI (MAP-MRI) is a method of using diffusion MRI to map tissue microstructure. To evaluate the accuracy and precision of MAP-MRI we use a test system consisting of an array of microscopic cylinders. We use both simulated data, computed using the multiple correlation function (mcf) method, and real diffusion imaging data of a special phantom. We report the accuracy and precision of several MAP parameters as a function of the signal-to-noise ratio of the non-diffusion weighted images.
