Flow-sensitive 3-dimensional MRI was successfully used to visualize different flow patterns in aneurysms of the ascending aorta. 33 aneurysm patients, 15 age matched normal controls and 15 healthy volunteers were examined. The study shows that there is a significant relationship between vessel diameter in the AAo, AAo/DAo diameter ratio and the incidence and strength of irregular blood flow and altered vessel wall parameters.
