This work describes a new method for non-contrast enhanced time-resolved dynamic MRA (dMRA) utilizing single- and multi-shot dynamic radial acquisition with golden angle view increment and k-space weighted image contrast (KWIC). The reconstructed 4D dMRA data set demonstrated a high quality, high temporal resolution dynamic series without apparent temporal blurring, yielding results comparable to standard Cartesian based dMRA approaches, but in a fraction of the scan time.
