Signal intensities in the liver were consistent with hepatic steatosis, a known disease of this rodent model. ROIs of 5×5 pixels were placed in 3 consecutive slices in each animal in the right side of the liver. Six of the twelve SHROBs (denoted SHROB*) were retrospectively identified as having unusually hyperintense livers. As compared to the other SHROBs, the six SHROB* were not statistically significantly heavier or younger, however they did have more visceral adipose tissue. Signal intensities in the ratio images were statistically significantly different between all groups except SHROB and SHR-DO (P<0.01). Signal intensities in muscle, kidney, and visceral adipose tissue were not different.
