Figure 8


Fig. 8. Tagged magnetization to assess local tissue deformation. Saturated longitudinal magnetization is applied in two orthogonal directions, which from the sagittal planar perspective (shown here) appears as a rectilinear grid of dark bands amidst the relative brightness of the rest of the MR image. Strain is determined in image post-processing by measuring the amount of deformation undergone by these bands of magnetization during the course of tissue motion.
