1 The comparative evaluation of three-dimensional magnetic resonance for carotid artery disease 
Donald K. Wilkerson, MD, Irwin Keller, MD, Reuben Mezrich, MD, PhD, William B. Schroder, MD, David Sebok, PhD, Judy Gronlund- Jacobs, Robert Conway, PhD, Michael A. Zatina, MD  Journal of Vascular Surgery  Volume 14, Issue 6, Pages (December 1991) DOI: /mva Copyright © 1991 Society for Vascular Surgery and International Society for Cardiovascular Surgery, North American Chapter Terms and Conditions

2 Fig. 1 3-D MR angiogram in a normal volunteer. Note ease of visualization of the carotid bifurcation and vertebral artery.

3 Fig. 2 MR angiogram demonstrates a critical stenosis in the ICA (arrow). Note loss of MR signal at the site of stenosis with immediate vessel reconstitution. We interpret this finding as a 99% stenosis.

4 Fig. 3 Vessel seen on MR in Fig. 2 is seen in anteroposterior projection on a conventional angiogram. A critical stenosis is seen in the proximal ICA.

5 Fig. 4 Relationship between ICA luminal diameter reduction measurements as determined by 3-D MR angiography and conventional angiography is plotted. Linear regression is represented by the solid line. The line of identity is represented by the broken line. When compared with conventional angiography, MR typically overestimates the degree of luminal reduction.
