Flow MRI of the carotid arteries has emerged as an important imaging field during the last decade and has been shown valuable for the assessment of hemodynamics in the context of atherosclerosis. In this study a 2D flow acquisition was accelerated using random undersampling and compressed sensing reconstruction. For validation of the reconstructed flow a phantom experiment was performed at different acceleration factors followed by an in vivo scan of the carotid arteries.
