Abstract：Objective To compare the diagnostic value of 256-slice CT angiography ( CTA ) and neck vascular ultrasound examination of the extracranial carotid artery disease in patients with acute cerebral infarction . Methods The test results of 256-slice CTA and neck vascular ultrasound examination of 258 cases of acute cere-bral infarction were retrospectively analyzed .Results 256-slice CT angiography and neck vascular ultrasound in the diagnosis of carotid artery stenosis of extracranial coincidence rate was 73.5%(1 138/1 548);mild to moder-ate stenosis diagnosis had a lower degree of consistency (κvalues were 0.01, 0.05);severe stenosis or occlusion diagnosis had a relatively high consistency (κvalue 0.34, 0.47).Detection of plaque with 256-slice CTA of the internal carotid artery and external carotid artery was much better than that with neck vascular ultrasound (175/50,χ2=74.89,P<0.01;29/4,χ2=19.14,P<0.01).Conclusion 256-sliceCTAinthediagnosisofextracranial carotid artery stenosis and plaque in patients with acute cerebral infarction is obviously superior to neck vascular color Doppler ultrasound .
