Box plots show signal ratio (SR) of the vessel wall to blood (a, b), CNR of vessel wall to blood (c, d), SR of vessel wall to blood (e, f), and CNR of the vessel wall to CSF (g, h). The central line represents the median, X the mean, the lower and upper margins of the box the 25–75th percentile, and the whiskers all data excluding outliers. The comparison of no DANTE sweep 50°–120° versus sweep 40°–120° acquisition (a, c, e, g) and among the no DANTE sweep 40°–120° and the DANTE acquisitions (b, d, f, h) are shown separately for each measure. No significant difference was found between the no DANTE sweep 50°–120° versus sweep 40°–120° acquisitions for any of the comparisons (p<0.05). For the comparisons among the no DANTE sweep 40°–120° and the DANTE acquisitions, * indicates significance with multiple comparisons (p<0.008 for CNR and p<0.005 for SR, as T2-weighted scan was included for the SR analysis).
