A double-tuned 1H/19F coil using PIN-diode switches was developed and evaluated its performance on a 9.4T preclinical MRI scanner. This proposed design uses an inductor rather than a capacitor in series with the PIN-diode so that the resonance frequency is shifted in the opposite direction compared to the conventional method. This is a key difference from the previous developments and in this way we can maintain the SNR or image quality of the X-nuclei (therefore 19F); the SNR is nearly as good as a single-tuned 19F coil.
