Acceleration-Selective Arterial Spin Labeling (AccASL) with double labeling and dual acceleration encoding (AENC) scheme (AccDD) was developed for consistent non-triggered peripheral non-contrast enhanced MR angiography. AccDD requires only 50% longer scan time than conventional single labeling and single AENC scheme and can provide better artery visualization. In addition, veins, with an expected flow slower than arteries, were more visualized using lower AENC acquisition of AccDD, indicating AccDD is sensitive to a wide flow velocity range. Consistent flow visualization in various flow conditions with patients can be expected.
