Abstract
The radio-frequency (RF) transmit and detection coils are transducers that excite and detect the magnetic resonance spectroscopy (MRS) signals. The signal-to-noise ratio, spatial and temporal resolution, spatial uniformity, and the efficiency with which the RF excitation power is used and lost to the measurement sample all depend critically on the RF coil's performance. Therefore, the success of the MRS measurement is determined in large part by the proper choice and application of the RF detection coil. The objective of this review is to provide an overview of the many coil design choices available, and how they can be used. A range of variants of the simple surface coil, concentric and phased-arrays of surface coils, solenoids, saddle coils, crossed-pairs of coils, 'birdcage' coils, transverse electromagnetic field (TEM), and transmission line coils are presented. These span the full range of frequencies and field strengths visited by in vivo MRS and offer options of linear, quadrature, and multinuclear operation. This should help guide the reader on the available options for their desired applications.
