dc.description.abstract | PURPOSE: We compared non-invasive imaging studies of CTA, TOF-MRA and CE-MRA to evaluate detecting internal carotid artery stenosis and occlusion. MATERIALS AND METHODS: We enrolled 20 patients with clinically suspected internal carotid artery stenosis and occlusion, or asymptomatic patient with more than 50% stenosis suspected on color Doppler ultrasonography for regular check-up. Prospectively, CTA, TOF-MRA and CE-MRA were performed, and sensitivity, specificity, positive predictive value, negative predictive value and accuracy of TOF-MRA and CE-MRA using CTA as a reference standard for detecting more than 50% stenosis were evaluated, and correlations of measured percent stenosis between 3 imaging studies were also evaluated. RESULTS: No significant difference was found between 3 imaging studies in measuring stenosis(p>0.05). Correlation coefficient was 0.932 between CTA and TOF-MRA, and 0.971 between CTA and CE-MRA. TOF-MRA had 83.3% sensitivity, 87.5% specificity, 71.4% positive predictive value, 93.3% negative predictive value and 86.4% accuracy for detecting more than 50% stenosis and occlusion. CE-MRA had 83.3% sensitivity, 93.8% specificity, 83.3% positive predictive value, 93.8% negative predictive value and 90.9% accuracy. CONCLUSION: TOF-MRA and CE-MRA provided high correlations in the evaluation of internal carotid artery stenosis and occlusion | - |
