With the introduction of parallel imaging the scan times for a high resolution 3D MRA dataset of the thoracic vasculature can be reduced dramatically and thus patients who today are unable to make a sufficient breath-hold may be easily imaged in the future. Furthermore dynamic imaging will be possible facilitating a comprehensive study of the thoracic aorta together with evaluation of the supraaortic vessels. It is likely also that functional as well as morphologic evaluation of the aortic valve will be possible in significantly less than 30 min. Finally, with the introduction of intravascular contrast agents it will become possible to perform both first pass imaging of the aorta and steady state imaging of the coronary arteries thereby permitting a complete non-invasive vascular work-up of patients with atherosclerotic disease.
