Fig 3. Quantification of an irregular, asymmetric carotid bulb stenosis with calcification. A, Axial CTA source image showing an asymmetric stenosis (white arrow). B, Axial magnification of the asymmetric carotid bulb stenosis with measurement calipers placed at the region of narrowest stenosis (calipers marked [A], showing measurement of 0.27 cm [2.7 mm]). C, Axial magnification of the asymmetric carotid bulb stenosis with the AGFA Impax 4.5 VT measuring the cross-sectional 2D area of 0.14 cm2 (14.0 mm2).
