  1. Quantitative values from the in vivo study for both imaging modalities are presented in the table. The standard deviation of the DSA velocity is provided from the triplicate scans. The magnification factor was calculated for each vessel by imaging a reference wire, of 3 cm in length, in the vessel of interest prior to injection
