An optimized 3D stack of stars with Sliding Interleaved Projection Reconstruction (SLIPR) provides improved carotid MRA over conventional Time of Flight (TOF) techniques. The stack of stars SLIPR technique takes better advantage of the inflow effect to maximize contrast to noise between blood and tissue. In addition, a multi-echo radial readout minimizes off resonance blurring, allows for fat water separation and shortens acquisition time compared with non-sliding 3D TOF techniques.
