Optimal Utilization of Spiral Computed Tomography
Carotid artery imaging by means of CT offers a great opportunity, since the vessels of the neck are larger than the coronary arteries and closer to the skin. Obtaining images of diagnostic quality is quite easy and, compared to other non-invasive modalities (i.e. duplex ultrasound) the panoramic view, which can comprise all the supra-aortic trunks (i.e. carotid arteries and vertebral arteries) from the aortic arch to the circle of Willis, is unmatched. The additional value of vessel wall imaging is also another advantage over conventional invasive angiography.
