New spectroscopy research reported from L.G. Kaiser and co-authors
December 23rd, 2008
"The limited bandwidths Of Volume selective RF pulses in localized in vivo MRS experiments introduce spatial artifacts that complicate spectral quantification Of J-coupled metabolites. These effects are commonly referred to as a spatial interference Or ''four compartment'' artifacts and are more pronounced at higher field strengths," researchers in the United States report. "The main focus Of this Study is to develop a generalized approach to numerical simulations that combines full density matrix calculations with 3D localization to investigate the spatial artifacts and to provide accurate prior knowledge for spectral fitting. Full density matrix calculations with 3D...
