Probing cardiomyocyte mobility with multi-phase cardiac diffusion tensor MRI
Fig 2
Calculation of HA, TA, and E2A at each cDTI voxel.
(A) Stack of Nb diffusion weighted images with an example LV ROI. The epicardial surface is shown in blue and the endocardial surface in red. (B-C) RGB colormap of the primary and secondary eigenvector orientation from the reconstructed diffusion tensors in the mid LV SA slice. (D-F-H) HA, TA, and E2A were calculated at each voxel after projection of the primary and secondary eigenvectors (E1 and E2) [2, 3, 22]. (E-G-I) HA, TA, and E2A maps in a representative volunteer (E2A is reported as absolute value).
