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 uncertain...
