Non-contrast Enhanced 4D Artery-selective MR Angiography using Spatially Selective Saturation

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.
