Maier IL, et al. - Given that the assessment of carotid artery flow by neurovascular ultrasound (nvUS) can be complemented by real-time phase-contrast (RT-PC) flow MRI which apart from quantitative flow parameters offers velocity distributions across the entire vessel lumen, the researchers compared RT-PC flow MRI of the carotids to nvUS. For this investigation, the feasibility and diagnostic potential of RT-PC flow MRI were assessed in 20 healthy volunteers in comparison to conventional nvUS. Researchers reported that MRI-derived velocities were lower and volumes were higher than by nvUS. Results of this study suggested that RT-PC MRI can add to clinical diagnostics of carotid stenosis.
