This study aims to understand how the volumes and speeds of intravenous injection of a recent type of contrast agent can be optimized in order to improve the information provided by medical images. To do this, five MRI scans lasting approximately 30 minutes will be performed on 10 healthy volunteers over a period of approximately 10 months. The images will then be analyzed by three radiologists who will view the images in different orders, without knowing which injection parameters were used. They will decide, based on their impressions but also on precise measurements in the images, which parameters produce the best images.
