Principal component analysis of MRI variables in DE50-MD and WT dogs. A Principal component 1 (PCA1) was significantly different between DE50-MD and WT dogs when all evaluated MRI variables were included. B When all gray matter variables were evaluated PCA1 (PCA1_gray) was significantly different between DE50-MD and WT dogs. C When all white matter variables were evaluated, there was no difference in PCA1 (PAC1_white) between DE50-MD and WT dogs (*p < 0.05, **p < 0.01, ***p < 0.001). Individual data, mean and standard deviation shown
