Cardiac MRI enables the assessment of whole-heart anatomy with both bright-and-black-blood contrasts. Additionally, quantitative myocardial T2 mapping is an emerging technique that enables non-contrast tissue characterization. However, conventional T2 mapping is performed under breath-hold with limited spatial resolution and coverage. Moreover, anatomic and quantitative images are acquired sequentially with different geometries and at different motion states. Here, we propose a novel quantitative 3D whole-heart sequence (qBOOST-T2) which provides co-registered 3D high-resolution bright-blood, black-blood and T2 map volumes from a single free-breathing scan. qBOOST-T2 was evaluated in a standardized T1/T2 phantom and healthy subjects and compared to current gold standard techniques.
