Three-dimensional pseudo-continuous arterial spin-labeling using turbo-spin echo with pseudo-steady state readout: A comparison with other major readout methods

Abstract

We evaluated 3D pseudo-continuous arterial spin labeling (pCASL) using turbo spin echo with a pseudosteady- state (PSS) readout in comparison with the other major readout methods of 3D spiral and 2D echoplanar 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.
