Brief Summary
Objective: To evaluate the technical performance of a novel cascaded wave imaging technique compared to plane wave imaging for blood flow imaging in patients with and without carotid artery stenosis. Study design: Observational, feasibility study in a total of 10 patients with and 10 patients without a hemodynamic significant carotid artery plaque. Intervention (observational): all participants will undergo a carotid ultrasound measurement including conventional duplex ultrasound and ultrasound based flow imaging using plane waves and cascaded waves.

Outcome Measures
Primary Outcomes (1)
2D velocity vector fields obtained by plane wave and cascaded wave imaging of the carotid artery
After study completion, average of one year
Secondary Outcomes (5)
Signal-to-noise ratio obtained from plane wave and cascaded wave imaging will be obtained and compared for different vessel depths
After study completion, average of one year
Cross-correlation maps of plane wave and cascaded wave imaging will be obtained and compared for different vessel depths
After study completion, average of one year
Velocity vector fields obtained from plane wave and cascaded wave imaging will be obtained and compared
After study completion, average of one year
Blood-flow related parameters, including vector complexity and vorticity, will be calculated from 2D velocity fields.
After study completion, average of one year
Spatiotemporal blood flow profiles obtained with plane wave, cascaded wave and conventional duplex ultrasound will be compared to assess the correlation between these techniques
After study completion, average of one year

Eligibility Criteria
10 patients with and 10 patients without a hemodynamic significant carotid artery stenosis
You may qualify if:
- Capacitated adult male or female (≥18 years old);
- Informed consent form understood and signed;
- Recent conventional duplex measurement of the carotid artery confirming either the absence or presence of a plaque
You may not qualify if:
- Hampered carotid blood flow imaging during conventional duplex/doppler measurements due to near to total carotid occlusion at the side of interest or a calcified plaque;
- History of radiation at the head-neck area;
- Participating in another clinical study, interfering on outcomes.
