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 9

The ST and DTI putative sheetlet-normal angles are compared for 5 rat hearts. The v 3 ST and e 3 DTI elevation (β’) angle maps of an equatorial short-axis slice are colored according to the −90° to +90° scale. Regions of similar and differing laminar normal orientation are shown in the magenta and black boxes respectively. The transmural orange line on the FLASH images indicates the transmural span quantified 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. The associated angle maps for the v 3 ST and e 3 DTI transverse (β”) angle are in Additional file 6: Figure DS2.
