The advent of 3T MR has improved imaging of the small vessels of the hand but still suffers from limitation of temporal resolution for assessing flow dynamics. We evaluated an imaging protocol combining TWIST and VIBE for the assessment of vascular pathology, building on our previous work with standard time resolved MRA.
