A dedicated double-tuned double-channel transmit receive surface coil setup is developed that enables the use of high B1+-fields in multi nuclei MRS of the human brain at 7T. The available B1+ field of up to 40 T and 100 T for respectively 1H and 31P allowed the use of short and high bandwidth adiabatic RF pulses, which are insensitive to the inhomogeneous nature of the B1+-field. Therefore accurately localized 1H and 31P MR spectra with high sensitivity could be obtained at 7T.
