Correlations between select DTI-derived parameters (ordinate) and measurements from histological sections (abscissa). Grayscale color of markers indicates transmural location (black: ENDO, white: EPI). a Fractional anisotropy from DTI exhibited a strong correlation with helix angle (R2 = 0.48, p < 0.001). b Mean diffusivity correlated with myocyte width:height ratio (R2 = 0.25, p < 0.01), and c Planar anisotropy correlated negatively with MFA (R2 = 0.24, p < 0.01)
