Abstract :
The purpose of this work is to demonstrate how 2D differential k-space sampling can be implemented with interleaving of the view (phase encoding) order, providing smoother temporal behavior and no spatial resolution penalty when compared to standard sequential k-space ordering. Implementation in a clinical setting provides a method for real-time bolus tracking and timing for contrast-enhanced 3D MR angiography
