A: Comparison of global measurement of mean kidney MTR values with the cystic index measured by histology. Although the mean MTR values are only a crude representation of the wealth of information contained in the MTR maps, the fact that they correlated closely with the cystic burden of the kidneys suggests that deeper probing can reliably extract not only macroscopic presentations of the disease but also subresolution tissue changes. B: Comparison of local measurement of mean kidney MTR values with the cystic index measured by histology. In this case, a much closer correlation between the results obtained by MT imaging and the ground truth histological measurements were obtained. Thus, at the local level, MT imaging conveys information regarding subresolution microscopic cysts.
