B‐Flow Imaging in Low Cervical Internal Carotid Artery Dissection

Generally, the vascular ultrasonographic examination is the first method in evaluation of internal carotid artery (ICA) dissection. B‐flow imaging (BFI), conversely, is a newer method of vascular ultrasonography. The objective of this study was to assess the accuracy and efficacy of BFI for the diagnosis of low cervical ICA dissection.
