Figure 4. Representative Look-Locker sequence MR images (3000/2.5; flip angle, 10°) obtained with a short-axis view of the left ventricle. There are two different injection sites: one immediately after injection of 0.1 mmol/mL gadodiamide (arrow) and one 15 minutes after injection of the same concentration (arrowhead). Zero crossing of the injection site immediately after injection is significantly faster compared with the injection site imaged 15 minutes after injection.
