Cardiovascular Magnetic Resonance Imaging (CMRI) is a well-established modality that allows not only non-invasive accurate blood flow quantification but also provides anatomical and biomechanical information about large vessel properties (e.g. aortic wall elasticity and distension) and central hemodynamics. The aim of our study is to use an MR-compatible aortic flow setup including two different elastic phantoms and validate MR-based pressure waveforms predicted by 1D blood flow model against invasive pressure measurements.
