We present a technique for the generation of four-dimensional angiographic data from 4D Flow MRI. Using registration between the timeframes of the 4D Flow MRI, the method concentrates information from the entire cardiac cycle into an angiographic dataset at one timeframe. This step is followed by another set of registrations to generate a time-resolved three-dimensional angiography (4D). Visual comparison of the generated data versus conventional techniques resulted in higher scores in all the regions evaluated. The resulting data allow for visualization of the cardiovascular anatomy throughout the cardiac cycle, facilitating anatomical orientation and enhancing visualization of 4D Flow MRI data.
