Reliability of two‐dimensional and three‐dimensional pseudo‐continuous arterial spin labeling perfusion MRI in elderly populations: Comparison with 15o‐water positron emission tomography

To investigate the reliability and accuracy of two pseudo‐continuous arterial spin labeling (pCASL) sequences, using two‐dimensional (2D) gradient‐echo echo planar imaging (EPI) and 3D gradient and spin echo (GRASE) as the readout, respectively.
