Details and patient eligibility

About

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.

Inclusion criteria

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

Exclusion criteria
