This work investigates probe construction materials for their signal contribution to ultrashort echo time spectroscopy and imaging. (1)H, (13)C, and (31)P spectra were obtained at a field strength of 9.4 T for 16 materials considered for use in probe and holder design and construction. Four of the materials were found to be suited for the construction of NMR probes, housing of RF coils, and holders for in vivo experiments.
