Fig. 3From: Optimization of quantitative time-resolved 3D (4D) digital subtraction angiography in a porcine liver modelBox-and-whisker plot of observed sideband ratio (SBR) on the natural log scale for 6-s and 12-s scan times with different injection rates in the 1st, 2nd, and 3rd order hepatic arterial branches. Horizontal lines in the box represent median values. Differences in observed SBR between scan times can be seen to decrease in the more distal (3rd order) branchesBack to article page
