, âgés de 24 et 33 ans) ont été inclus pour un examen cardiaque à l'IRM 3T. Une méthode 3D de cartographie T 1 basée sur la VFA, a été utilisée pour faire les cartes de T 1, Deux volontaires sains (1 homme, 1 femme

, Pour la respiration contrôlée, une synchronisation cardiaque et respiratoire a été utilisée. Les signaux des ceintures respiratoires et de l'ECG ont été enregistrés par un système de monitoring MAGLIFE (Schiller Medical, France) et utilisés pour générer un trigger cardiaque en passant par le SAEC

, Un programme a été développé en Matlab® pour calculer le T 1 en mesurant les intensités des images obtenues avec des angles différents

, Pour la reconstruction en respiration libre, la méthode proposée ci-dessus (paragraphe 3.2.2) a permis d'obtenir une carte T 1 à partir des trois jeux de données en respiration libre (soit neuf volumes d'acquisitions)
