The use of ultrasonography and especially of contrast-enhanced ultrasonography (CEUS) in the diagnosis of vascular pathologies before and after interventions has significantly increased over the past years due to the broader availability of modern ultrasound systems with CEUS capabilities and more trained user experience in this imaging modality. For the preinterventional and postinterventional...

Carotid duplex ultrasonography is a noninvasive technique for hemodynamically significant stenosis detection and cardiovascular risk estimation. Anatomic information of carotid arteries is provided by B-mode scanning. Hemodynamic features are displayed color-flow and pulsed Doppler imaging. Examination technique, normal carotid anatomy and flow pattern, and potential limitations are presented.
