Pseudo-continuous transfer insensitive labeling technique

Cheng Ouyang, Bradley P. Sutton
2011 Magnetic Resonance in Medicine  
Transfer insensitive labeling technique (TILT) was previously applied to acquire multi-slice cerebral blood flow (CBF) maps as a pulsed arterial spin labeling (PASL) method.  ...  In this work, we propose to address these challenges by making the original TILT method into a novel pseudo-continuous ASL approach, named pseudo-continuous transfer insensitive labeling technique (pTILT  ...  The content is solely the responsibility of the authors and does not necessarily represent the official views of the National Institute on Aging or the National Institutes of Health.  ...
