Key result
Among 54 patients with 73 carotid lesions, power Doppler visualized stenosis more accurately than color-flow Doppler and was superior to angiography for differentiating plaque surface morphology.
Why the study?
Does power Doppler ultrasonography improve the accuracy of diagnosing carotid artery stenosis and visualizing plaque surface compared to color-flow Doppler and angiography in patients with >50% extracranial internal carotid artery stenosis?
Observational (n=54)

Power Doppler is a superior noninvasive imaging technique compared to color-flow Doppler for diagnosing carotid artery stenosis and assessing plaque morphology.
No takes yet. Share an insight, caveat, or question.
Power Doppler may aid noninvasive carotid assessment; leaves open prospective validation before practice change.
Griewing et al. (1996) conducted an observational in Carotid artery stenosis (n=54). Power Doppler ultrasonography vs. Color-flow Doppler and digital subtraction angiography was evaluated on Visualization of carotid stenosis and plaque surface morphology. Among 54 patients with 73 carotid lesions, power Doppler visualized stenosis more accurately than color-flow Doppler and was superior to angiography for differentiating plaque surface morphology.
