Alterations of Renal Function in Patients with Diabetic Kidney Disease: A BOLD and DTI Study

Figure 5

Correlations between clinical indexes and MRI parameters.Legends: Heatmap analyzing the correlation between the cortex and medulla , FA, and ADC values and the eGFR, BUN, HbA1c, uAlb, and Cys C levels of all the groups. The colormap was drawn with a double gradient. The r value ranges from −1 to 1. Blue represents the maximum value and red represents the minimum value. The linear correlations of clinical indexes with MRI data /M.FA were also shown above. A p value < 0.05 was considered significant.
