Echo planar spectroscopic imaging

Echo planar spectroscopic imaging (EPSI) allows for mapping one spatial dim ension and the spectroscopic dimension in a single readout. Modern clinical magnetic resonance imaging scanners are becoming widely equipped with echo planar imaging gradient capabilities Thus there exists an enormous potenti al for EPSI to facilitate clinical magnetic resonance spectroscopy. Here. a pedagogical analysis of how the spectral and spatial encoding occur within EPSI is provided along with demonstrations of the technique and a discussi on of the inherent signal-to-noise limitations.
