To demonstrate the majors findings in carotid artery dissection on the Doppler ultrasonography. To review and illustrate role of Doppler ultrasonography in carotid artery dissection and their complications. What cannot miss in the ultrasonography report of carotid dissection?    

Cervical artery dissections (CAD) are more common in the internal carotid arteries (ICA), 70% in the cervical and petrous segments, mainly 2-3 cm distal to the carotid bulb. These segments are easily accessible by ultrasound. The Doppler ultrasound (Doppler US) can make initial screening, diagnosis and monitoring of dissection in the proximal segments of the ICA. Computed tomography (CT) and magnetic resonance imaging (MRI) are the best methods in the evaluation of CAD. The present study aims to describe by practical cases the role and major abnormalities in the Doppler US of ICA dissections. Doppler US is a low cost exam that can assist in the diagnosis and monitoring of CAD. That can demonstrate the tapering column flow with abnormal pulsed wave Doppler up to 90% of cases of dissection. Moreover, it is able to determine the flow dynamics of the dissection. CT and MRI do not allow determining the flow dynamics It is important for all radiologist know the majors abnormalities in carotid artery dissection on the Doppler US.
