Accelerated high-resolution free-breathing 3D whole-heart T₂-prepared black-blood and bright-blood cardiovascular magnetic resonance.

ABSTRACT:

Background

The free-breathing 3D whole-heart T₂-prepared Bright-blood and black-blOOd phase SensiTive inversion recovery (BOOST) cardiovascular magnetic resonance (CMR) sequence was recently proposed for simultaneous bright-blood coronary CMR angiography and black-blood late gadolinium enhancement (LGE) imaging. This sequence enables simultaneous visualization of cardiac anatomy, coronary arteries and fibrosis. However, high-resolution (< 1.4 × 1.4 × 1.4 mm³) fully-sampled BOOST requires long acquisition times of ~ 20 min.

Methods

In this work, we propose to extend a highly efficient respiratory-resolved motion-corrected reconstruction framework (XD-ORCCA) to T₂-prepared BOOST to enable high-resolution 3D whole-heart coronary CMR angiography
