Magn Reson Med Sci. 2019 Apr 10;18(2):170-177. doi: 10.2463/mrms.tn.2018-0031. Epub 2018 Oct 12.

Abstract

We evaluated 3D pseudo-continuous arterial spin labeling (pCASL) using turbo spin echo with a pseudo-steady-state (PSS) readout in comparison with the other major readout methods of 3D spiral and 2D echo-planar imaging (EPI). 3D-PSS produced cerebral blood flow (CBF) values well correlated to those of the 3D spiral readout. By visual evaluation, the image quality of 3D-PSS pCASL was superior to that of 2D-EPI. The 3D-PSS technique was suggested useful as pCASL readout.

Keywords: arterial spin labeling; cerebral blood flow; pseudo-steady state.
