The PROPELLER technique was restricted to static imaging due to its multi-shot nature. By introducing the concept of keyhole, images that were reconstructed by the data-sharing PROPELLER technique have the temporal resolution of the blades and the spatial resolution of the conventional PROPELLER images. In this work, simulation on dynamic contrast-enhanced perfusion imaging and in-vivo T2 estimation experiments were used to demonstrate the effectiveness of the proposed method. Results show that dynamic images showing behavior highly consistent with full-k-space images could be obtained without prominent artifacts.
