Aim:The aim of this study was to investigate the correlation between the severity of carotid stenosis determined with 64-multidetector row computed tomographic angiography (CTA) (64-MDCTA) using the ‘‘common carotid’’ (CC) method and color Doppler ultrasound (CDUS) findings.Methods:Two hundred and eighty-six internal carotid arteries (ICAs) of 143 patients with a history of transient ischemic attack/stroke and suspected ICA stenosis who were referred for cervical CTA were examined. Plaque location, plaque type and stenosis severity were reported with CDUS and CTA. Stenosis severity was calculated with CTA using the CC method. The results were compared retrospectively.Results:Plaques were observed in a total of 202 (72.2%) ICAs by CDUS and using MDCTA in a total of 200 (71.4%) ICAs. The plaques were classified according to the plaque type as soft, calcified and mixed by CDUS and by MDCTA Stenosis ≥70% was observed in 12.2% of cases on CDUS and in 10.0% of cases on CTA. A correlation of 91% (r=91, p<0.001) was observed between findings of CDUS and CTA for the determination of the grade of carotid stenosis.Conclusion:Stenosis measurement done using the CC method is highly correlated with CDUS findings. The CC method is a candidate for widespread use in carotid stenosis measurement in routine practice.
