New publication in Magnetic Resonance in Medicine!
We are delighted to share a new publication entitled "Three- dimensional gradient and spin- echo readout for time- encoded pseudo- continuous arterial spin labeling: Influence of segmentation factor and flow compensation", which is part of the doctoral thesis defended by our alumni and collaborator André Paschoal, under supervision of Professor Renata Leoni, that also co-authors the paper.
In this study, the authors investigated pulse sequence components for pseudo-continuous Arterial Spin Labeling acquisition. While Hadamard-encoded is a time efficient way of labeling in pCASL acquisition, 3D GRASE is the recommended readout approach. In this paper, the authors evaluated the influence of the number of segments in 3D GRASE readout regarding the tSNR and blurriness in z-direction.Furthermore, it was also analyzed the impact of flow compensation gradients in visualizing the vascular components of ASL signal as well as its passage to the brain tissue level.
