(A.) Bar graph depicting both the pre and post-verapamil mean vessel diameters from six positions along the length of the common carotid artery (CCA) (2.85 ± 0.14 mm and 3.45 ± 0.18 mm, respectively), and (B.) cross-sectional areas (6.41 ± 0.61 mm2 and 9.39 ± 1.0 mm2, respectively). Note the 46.7% increase in mean cross-sectional area after verapamil administration.
