DOI: 10.1002/mrm.29536
Abstract: Filter exchange imaging (FEXI) and diffusion time (t)‐dependent diffusion kurtosis imaging (DKI(t)) are both sensitive to water exchange between tissue compartments. The restrictive effects of tissue microstructure, however, introduce bias to the exchange rate obtained… read more here.
