In this study we propose to validate a 4D flow technique that acquires data on the whole heart and great vessels using a self-respiratory gating technique. The method allows retrospective flow quantification from data obtained in a single free breathing scan. In 15 volunteers, the method was compared with 2D flows and with a 4D flow data obtained without respiratory gating. Result showed an excellent agreement with the clinically used 2D sequence. When applied in a congenital heart patient the technique showed to be very valuable for retrospective analysis of flow in any arbitrary plane and direction.
