A simple technique is described for scan time reduction in proton echo planar spectroscopic imaging (EPSI) of the human brain. Scan time is reduced by 25% while preserving spatial resolution and the field of view using a circular k-space phase-encoding pattern. Metabolic images created using square or circular-encoding are nearly indistinguishable.
