Weighted averaging in spectroscopic studies improves statistical power
PURPOSE: In vivo MRS is often characterized by a spectral signal-to-noise ratio (SNR) that varies highly between experiments. A common design for spectroscopic studies is to compare the ratio of two spectral peak amplitudes between groups, e.g. individual PCr/γ-ATP ratios in (31) P-MRS. The uncertai...
