From: Comparison of diffusion tensor imaging by cardiovascular magnetic resonance and gadolinium enhanced 3D image intensity approaches to investigation of structural anisotropy in explanted rat hearts

Figure 13

The putative ST and DTI myocyte angles are compared for 5 rat hearts. The putative myocyte helix angle α’ and transverse angle α” in an equatorial short-axis slice are colored according to the −90° to +90° scale shown. The transmural orange line on the FLASH images indicates the transmural span quantified in in Figure 14. DTI: Scan #1, 6-direction, b = 1000 s/mm2; ST: Scan #8, DTW = 3, STW = 3. FLASH: fast low angle shot; ST: structure tensor of FLASH data; DTI: diffusion tensor magnetic resonance imaging; DTW: derivative template width STW: smoothing template width. The symbols for vectors and derived angles are defined in Table 2.
