Fig. 4From: Optimization of quantitative time-resolved 3D (4D) digital subtraction angiography in a porcine liver modelBox-and-whisker plot of observed 4D-DSA area for 4-Fr and 5-Fr catheter sizes with different injection rates in the 1st, 2nd, and 3rd order hepatic arterial branches. Horizontal lines in the box represent median values. Higher injection rates yielded higher 4D-DSA areas and 4-Fr catheters led to a slightly higher 4D-DSA area across all branchesBack to article page
