128-MSCT Angiography Combined with Color Doppler Flow Image in the Assessment of Carotid Artery Stenosis

Objective: To assess the value of 128-slice CT angiography(MSCTA) combined with color Doppler flow image in the assessment of carotid artery stenosis(CAS). Methods: fifty-eight patients with extracranial carotid stenosis including 116 segments were examined by MSCTA and CDFI within one week, the results of DSA were used as a golden standard. The results of MSCTA and CDFI were comparatively analyzed. Results: The consistent rates in diagnosis on s light-stenosis, mild-stenosis, moderate-stenosis, severe-stenosis and complete occlusion with MSCTA and CDFI was 84.6%, 79.5%, 86.7%, 92.8% and 82.6%, 76.7%, 85.1%, 91.2. The consistency were excellent between MSCTA and CDFI(χ²= 265.261, ν = 16, P<0.001, Kappa =0.870). Conclusions: MSCTA compared with CDFI had excellent consistency with DSA in diagnosis of carotid artery stenosis. MSCTA unite CDFI can be used early screen in artery stonosis. which can be used as an important basis for carotid stenosis screening in primary hospital.
