CT-angiography and doppler ultrasonography in atherosclerotic carotid artery disease. A comparative study (original) (raw)

Abstract

Background: Different diagnostic modalities to investigate atherosclerotic carotid artery disease (ACAD) are nowadays available. The aim of this study was to test the concordance of the findings of the two most widely used diagnostic modalities namely computed tomography angiography (CTA) and doppler ultrasonography (DUS). Material and methods: 29 patients with acute ischemic stroke were subjected to CTA and DUS and included in this analysis; 17 patients were males (59 %). The mean age was 70.5 ± 8 years (Mean ± SD). The correlation and the degree of concordance between the findings of CTA and DUS were tested. The associations between the occurrence of ACAD and the degree of severity of stenosis with the age, the gender and the side of stenosis were also tested. The statistical significance was set to < 0.05. Results: This study showed almost perfect agreement between CTA and DUS in detection of stenosis with kappa value of 0.92 (95 % CI 0.82–1.02). Intraclass correlation coeffic...
