Objectives The aim of this retrospective study was to compare intracranial arterial stenosis in patients with stroke using 3 different methods: transcranial color-coded duplex sonography, computed tomographic (CT) angiography, and digital subtraction angiography a common clinical practice. Methods Sixty-seven (47 male 20 female; age range, 23–79 years; mean ± SD, 62.0 9.5 years) were enrolled over 40 months. All underwent examinations the arteries CT angiography. Findings divided into 4 groups: normal, mild (<50%), severe (50%–99%), occlusion. Results Because technical reasons or an insufficient bone window, 465 536 segments 67 evaluated; 12 stenotic 15 occluded detected sensitivity, specificity, positive predictive value, negative value sonography comparison as reference standard 88.9%, 94.8%, 51.1%, 99.3% 81.5%, 98.7%, 78.6%, 98.6%, respectively. agreement between 93.8% (κ = 0.559); it 93.9% 0.588); 96.6% 0.697). Conclusions Moderate found evaluation stenosis. Computed are sufficient for assessment diagnosis.
