Quantitative MRI has many advantages over traditional contrast weighted methods, which may be more suitable for multi-centre studies across different MRI systems. This study describes the development of a 3D black blood T₂ mapping sequence with the combination of compressed sensing and data-driven parallel imaging. Phantom and volunteer experiments were performed to optimise the parameters and patients with atherosclerotic carotid artery disease were scanned using the optimised sequence.
