PurposeTo compare the respective ability of PRESS and sLASER to reveal biological relationships, using age as a validation covariate at 3 T.MethodsMRS data were acquired from 102 healthy volunteers using PRESS and sLASER in centrum semiovale and posterior cingulate cortex (PCC). Acquisition parameters included TR/TE = 2000/30 ms, 96 transients, and 2048 datapoints sampled at 2 kHz.Spectra were analyzed usingOsprey. SNR, FWHM linewidth of total creatine, and metabolite concentrations were extracted. A linear model was used to compare SNR and linewidth. Paired t‐tests were used to assess differences in metabolite measurements between PRESS and sLASER. Correlations were used to evaluate the relationship between PRESS and sLASER metabolite estimates, as well as the strength of each metabolite‐age relationship. Coefficients of variation were calculated to assess inter‐subject variability in each metabolite measurement.ResultsSNR and linewidth were significantly higher (p< 0.01) for sLASER than PRESS in PCC. Paired t‐tests showed significant differences between PRESS and sLASER in most metabolite measurements. PRESS‐sLASER measurements were significantly correlated (p< 0.05) for most metabolites. Metabolite‐age relationships were consistently identified using both methods. Similar coefficients of variation were observed for most metabolites.ConclusionThe study results suggest strong agreement between PRESS and sLASER in identifying relationships between brain metabolites and age in centrum semiovale and PCC data acquired at 3 T. sLASER is technically desirable due to the reduced chemical shift displacement artifact; however, PRESS performed similarly in homogeneous brain regions at clinical field strength.
