In this study, we present a method for dynamic
artery-selective non-contrast enhanced magnetic
resonance angiography. This method is based on the
inflow effect of arterial blood. Two individual cylinder
pulses are placed over two major brain feeding arteries,
resulting in the image acquisition of the third
remaining vessel. Over a time-course of 1450ms, six
individual temporal phases with a frame-rate of 200ms
can be acquired, while the total acquisition time is
kept to five minutes. This method was successfully
applied in healthy volunteers, visualizing even the
distal parts of the individual flow territories of the
intracranial arteries.
