title: Computed tomography angiography.
abstract: Spiral computed tomography angiography is a relatively new noninvasive technique capable of rapid imaging of the carotid artery. Computed tomography angiography usually is performed in a 30-second scan time and images iodinated contrast as it fills the vascular lumen. Studies comparing computed tomography angiography with conventional angiography show sensitivities and specificities that rival any of the other noninvasive imaging techniques for the detection of carotid artery stenosis and occlusion.
