Ultrasound/doppler study of the carotid arteries can be used to detect carotid stenosis or dissection of the precerebral arteries.


Doppler ultrasound of carotid arteries may assess the degree of carotid stenosis, hence may help in determining the medical or surgical treatment to prevent recurrent episodes of ischemic stroke.[1][2][3]

Class I
3.     In patients with symptomatic anterior circulation cerebral infarction or TIA who are candidates for revascularization, noninvasive cervical carotid imaging with carotid ultrasonography, CT angiography (CTA), or magnetic resonance angiography (MRA) is recommended to screen for stenosis.(Level of Evidence: B-NR)
