Abstract:
Objective To evaluate the diagnostic value of 64 multidetector-row CT angiography for internal carotid artery(ICA)stenosis and the application in the follow-up of carotid endarterectomy and percutaneous transluminal stenting.Methods Forty transient ischemie attack(TIA)patients with interpretable CTA and DSA of the cervical carotid arteries were selected from May 2005 to December 2005. This yielded a total of 80 vessels.The CTA curved planar reformations(CPR)and DSA images referenced to the distal cervical internal carotid were graded by two senior neuroradiologists blindly,according to the North American Symptomatic Carotid Endarterectomy Trial(NASCET)guidelines.The paired-t test was used to verify the statistical significant difference between pre-operating and post-operating of carotid endarterectomy or percutaneous transluminal stenting in measuring the vascular diameter and area of cross section using CTA.Results When the 70% stenosis was used as the cut-off value,the seasitivity,specificity,negative predictive value,and the positive predicting value were 97%,95%,95%,and 98%,respectively.There was statistically significant difference in measuring the vascular diameter(P
