ABSTRACT

Intravascular navigation or virtual endoscopy was performed after the assessment of carotid artery stenosis by magnetic resonance angiography. The paths that were reconstructed, corresponded to the anatomic regions identified as stenotic due to plaques, thrombus, or to thickening of the vessel wall. Findings of color were used as important standard of reference for the analysis of plaques and type of flow through the affected area. Based upon two dimensional time-of-flight magnetic resonance (2D TOF MR) reconstructions of the same area we obtained views of the vessel walls, facilitating both qualitative and potentially quantitative analysis. We believe this will enhance diagnostic capabilities. With the advantage of visualizing the vascular lumen we think this technique will be useful in analyzing the integrity of stents and follow up assessment after balloon angioplasty.
