Figure 1 Identical short-axis slices from one animal scanned at serial time points using the delayed-enhancement technique with an adjusted inversion time (TI) (upper row) and a fixed TI (lower row). Using an adjusted TI (upper row), both the appearance of the images and the spatial extent of enhancement did not change up to 40 min after injection of contrast agent. However, using a fixed TI (lower row), both the general appearance of the images and the spatial extent of enhancement changed over time.
