Functional Magnetic Resonance Imaging in Acute Kidney Injury: Present Status

Figure 3

Representative diffusivity and kurtosis maps obtained from diffusional kurtosis imaging for one healthy Sprague Dawley rat. (a) Representative locations of regions of interest (ROIs) for the cortex and medulla at the mid-zone of the right kidney on the  mm²/s image. The same ROIs were then copied to maps of all metrics. (b–h) Maps of the fractional anisotropy (FA), mean diffusivity (MD), radial diffusivity (), axial diffusivity (), mean kurtosis (MK), radial kurtosis (), and axial kurtosis () are given, respectively.
