Abstract In this work, echo-planar spectroscopic imaging (EPSI) with flyback readout gradient-echo train was implemented in a preclinical MR scanner. The aim of this study is to visualize and quantify the ghost spectral lines produced by two, three a

Scalar coupling is an important parameter in nuclear magnetic resonance (NMR). The proton-proton coupling constant JH-H provides valuable information on molecular structure. However, determining JH-H value in complex coupling networks is still challe

Purpose Spectroscopic imaging could provide insights into regional cardiac triglyceride variations, but is hampered by relatively long scan times. It is proposed to synergistically combine echo-planar spectroscopic imaging (EPSI) with motion-adapted
