The application of 16-detector row CT angiography in the diagnosis of carotid artery stenosis

Objective To study the value and the technique dominance of 16-detector row CT angiography(CTA) in the diagnosis of carotid artery stenosis.Methods To analyze the CTA results retrospectively of 17 cases of carotid artery stenosis confirmed by clinic or DSA examination,and to evaluate the display of the blood vessel.7 cases of them are compared between DSA examination and CTA results.Results There are 17 cases whose CTA display rate is 100% of common carotid artery,external carotid artery and internal carotid artery.18 branches internal carotid artery stenosis,in them 10 branches light stenosis,4 branches midrange stenosis,3 branches heavy stenosis,1 branches obstruction.This software can show the vessel stenosis,calcification and the relation with surrounding sclerotin clearly.It shows the stenosis section exactly and calculates the degree of stenosis automatically.Conclusion The 16-row CT angiography is no-trauma and can be the first choice in diagnosis of carotid artery stenosis.It can show the stenosis section and its relation with the vicinal structure clearly.It has the characteristics of convenience,accuracy and peculiarity.
