- The first scan was carried out at 2 h and subsequent serial scans were carried out without moving the heart in the scanner. A baseline scan taking 1 h 50 m for 6 diffusion directions at b = 1000 s:mm2 was performed at serial time-points throughout the imaging study to explore any changes in diffusion as a result of time elapsed from killing/perfusion fixation. Interspersed between these baseline scans two T1W FLASH scans were performed at 50 × 50 × 50 μm resolution, as well as a series of diffusion scans with different numbers of directions and different b-values. All diffusion scans were at 200 × 200 × 200 μm resolution. Ref #: reference number for this scan; a– time post-fixation (h:min); bduration (h:min); Type: DTI - diffusion tensor magnetic resonance imaging; T1W is T1-weighted FLASH; FLASH: fast low angle shot; n-dir: number of diffusion directions; NA: not applicable.
