This
study aims to assess an alternative reconstruction method that utilizes the
temporal information from a 4D radially encoded flow scan. The method creates and angiogram from dynamic
time frames instead of a time averaged reconstruction. While the approach
increases background noise, it alleviates the problem of signal drops and
voids from reversing flow patterns. The utility of the algorithm was
evaluated in a group of 4 volunteers and 6 patients, demonstrating improved
signal consistency along the aorta.
