This study showed a novel non-contrast MR angiography sequence based on gradient echo DIXON sequence with flow-independent relaxation-enhanced method (Relaxation-Enhanced Angiography without Contrast and Triggering: REACT) for evaluating thoracic outlet syndrome. This could provide high-quality MRA with robust fat suppression entire the subclavian area with/without arm abduction.
