The current study compares 3T pseudo-continuous arterial
spin labeling cerebral blood flow measurements acquired
in two centers, at a General Electric (GE) and Philips
scanner. The main difference between the GE and Philips
acquisitions is the readout module: 3D vs. 2D. This
study shows that arterial spin labeling results from
different vendors can be compared for the total gray
matter region of interest. However, for the white matter
or for smaller gray matter regions standardization of
readout modules between vendors is warranted.
