Golden-angle radial sampling based on single-echo bSSFP has been increasingly used in MRI. In a method known as ETGAR (echo-train golden-angle radial), a series of spokes separated by a golden angle are acquired within a TR to accelerate data sampling. A main disadvantage is that the large inter-echo steering gradients can lead to a longer TR and trigger eddy currents. We herein demonstrate an alternative golden-angle radial sequence – ETGAR-II – to overcome the afore-mentioned issues. This novel sequence, together with an integrated phase-correction algorithm has been demonstrated on phantoms and human to obtain high quality images with 36% scan time reduction.
