This study intended to evaluate the effect of the material of phantom-container on the MRS signal in 3T MRI. Three phantom-container consisting of clear laboratory-glass, PET-bottle, and falcon-tube was used. The metabolites contained 6 mM Cr and 3 mM Cho. FWHM and SNR of Cho and both peaks of Cr were calculated. FWHM of all the peaks of glass-phantom was 50.08 and 19.48 % fewer than those provided by PET and falcon-tube; also, the SNR of the all the peaks of the PET and falcon-tube were by average 77.99 and 91.18 % fewer than the peaks provided by glass-phantom. The laboratory-glass is a good material for building MRS phantoms since it does not affect the baseline-noise, FWHM, and SNR of the spectra. It was also revealed that the size of the phantom and the distance between the spectroscopy volume and phantom walls were important and can affect the baseline-noise.
