  • Title: Usefulness of susceptibility-weighted imaging for voxel placement in MR spectroscopy.
    Author: Josey L, Al Sayyari A, Buckley R, Coulthard A.
    Journal: AJNR Am J Neuroradiol; 2009 Apr; 30(4):752-4. PubMed ID: 19039049.
    Abstract:
    MR spectroscopy is used to provide in vivo biochemical information about cerebral metabolites. Magnetic field homogeneity secondary to anatomic interfaces, hemorrhage, or necrosis may lead to suboptimal MR spectroscopy. Susceptibility-weighted imaging (SWI) can identify field inhomogeneity and could be used to guide MR spectroscopy voxel placement, leading to higher-quality MR spectroscopy examinations.
