Free-breathing three-dimensional whole-heart adiabatic T1ρ mapping for non-contrast tissue characterization at 0.55T.

ABSTRACT:

Background

Commercial 0.55T low-field magnetic resonance imaging (MRI) systems have recently become available, offering the potential to enhance global accessibility to MRI. T1ρ mapping is an emerging quantitative cardiac MR imaging technique capable of detecting myocardial disease without the need for contrast administration. However, experience with cardiac T1ρ mapping at low-field strength remains limited. This study aims to develop and validate an efficient, free-breathing three-dimensional (3D) high-resolution adiabatic T1ρ mapping sequence for non-contrast whole-heart tissue characterization at 0.55T.

Methods

The proposed 3D T1ρ mapping research sequence acquires four interleaved volumes with different contrast weightings using saturation and adiabatic spin-lock prepar
