Spectral fitting metrics (SNR, FWHM, and metabolite CRLBs) averaged over all five volunteers

	SNR [a.u.]	FWHM [Hz]	tCr CRLB [%]	tCho CRLB [%]	tNAA CRLB [%]
iMUSICAL	21.3 ± 3.7 (21.8)	13.5 ± 2.4 (13.5)	3.7 ± 0.5 (4)	3.9 ± 0.4 (4)	2.1 ± 0.3 (2)
aMUSICAL static	19.6 ± 3.4 (19.4)	13.6 ± 2.5 (13.5)	3.8 ± 0.5 (4)	3.9 ± 0.4 (4)	2.2 ± 0.4 (2)
aMUSICAL moved	19.5 ± 3.3 (19.3)	13.6 ± 2.6 (13.6)	3.9 ± 0.6 (4)	3.9 ± 0.4 (4)	2.2 ± 0.4 (2)

Mean values with standard deviations and medians in brackets are provided. The best results were obtained using iMUSICAL. The differences between iMUSICAL and either of the two aMUSICAL tests were larger than among the two aMUSICAL approaches.

Abbreviations: CRLBs, Cramer‐Rao lower bounds; FWHM, full width at half maximum; SNR, signal‐to‐noise ratio; tCho, total choline; tCr, total creatine; TNAA, total N‐acetyl‐aspartate.
