The balanced sequence created good contrast between the bowel and the surrounding mesentery and showed distinct bowel displacement between t=0 and t=15 minutes (Figure 1A-B).

These displaced bowel loops can be seen in green and pink overlay view (Figure 1C) After registration, however, almost no displacement is visible anymore (Figure 1D), indicating a good alignment of the main structures due to registration.
