FIG 1. Evaluation of reconstruction accuracy of 3D-CDS compared with that of DSA in a patient with moderate ICAS.
Note corresponding findings in two reconstructed color (shown here in black and white) multi-intensity-projection 3D images (A and B) and a DSA image (C) indicate excellent reproducibility. The single asterisk denotes moderate ICAS, the double asterisk denotes high-grade external carotid artery stenosis, and the open circle denotes mild ICAS.
