Morphological Features of the Internal Carotid Artery

Combining high-frequency and low-frequency probes is better than high-frequency probes alone to assess morphologic features of the ICA in duplex ultrasonography. Low-frequency convex probes should be added to traditional ultrasonography for the evaluation of morphologic features of the ICA before carotid endarterectomy, carotid artery stenting, and CA angioplasty.
