Consistency of hemodynamics information measured by 4D Flow MRI and 2D phase contrast MRI in patients with mild to moderate carotid artery stenosis

Motivation: The blood flow of carotid artory can be assessed by the standard 2D PC MRI, as well as the advanced 4D Flow MRI. Goal(s): The aim of this study is to test the potential of 4D flow for accuracy of quantification of carotid flow parameters compared to the reference standards 2D PC MRI in patients. Approach: 4D Flow MRI and 2D PC MRI were performed in patients with carotid artery stenosis. Quantitative hemodynamics of carotid arteries were measured in 2D PC and 4D Flow MRI. Results: 4D Flow MRI and 2D PC MRI had a good consistency in the evaluation of carotid hemodynamics. Impact: This study found that 4D Flow MRI and 2D PC MRI had a good consistency in the evaluation of carotid hemodynamics in patients with mild to moderate carotid artery stenosis.
