In this work, a free breathing three dimensional MOLLI implementation using respiratory navigation and novel inversion time gating is presented. Mapping of T1 has been applied in patients with diffuse fibrosis showing differences in quantitative values between disease and control groups. Probably the most widely used cardiac T1 mapping method is MOLLI. MOLLI is acquired in a breath hold which limits spatial resolution and restricts coverage to a single slice. Free breathing three dimensional T1 mapping of the whole ventricle as introduced in this work can be performed using respiratory navigation and inversion time gating, resulting in high-quality T1 maps.
