Quantitation Error in (1)H MRS Caused by B1 Inhomogeneity and Chemical Shift Displacement.

CONCLUSION: CSD and inhomogeneity of reception sensitivity cause amplitude modulation along the direction of chemical shift on the spectra, resulting in a quantitation error. This error may be more significant at higher B0 field where CSD and B1 inhomogeneity are more severe. This error may also occur in reception using a surface coil having inhomogeneous B1. Since this type of error is around a few percent, the data should be analyzed with greater attention while discussing small differences in the studies of (1)H MRS.
