Abstract

To determine the utility of spiral computed tomography(CT) in the evaluation of carotid artery stenosis, spiral CT images of 10 patients were compared with both ones of conventional angiography and magnetic resonance(MR) angiography. The severeness of stenosis was determined for each Internal carotid artery on the basis of arterial narrowness : mild stenosis : 40 % or less, moderate stenosis = $40{\sim}70%$, severe stenosis = greater than 70 % of arterial narrowness. The short examination and clear depiction of the arterial lumen In areas of complex or low flow make CT angiography attractive alternative to MR angiography. Spiral CT angiography shows normal and abnormal carotid anatomy well when compared with conventional anglography.
