The time spatial labeling inversion pulse (t-SLIP) technique is used for non contrast enhanced MR angiography imaging. It produces bright blood spin labeling images by using a single acquisition with a combination of a spatially nonselective inversion pulse and a spatially selective inversion pulse. The nonselective pulse inverts the magnetization of the entire imaging area. The spatially selective pulse, applied upstream of the arteries of interest, reverts those protons to full magnetization. A pre defined time delay between tagging and imaging allows the tagged spins to reach the imaging region and suppresses background tissue within the imaging region to some extent.
