MRI of inert fluorinated gases is a developing method for pulmonary ventilation imaging, but image quality is constrained by low spin density. Additionally, proton imaging is desirable for complementary structural information from the lungs. Here, an 8-element transmit/receive coil array for 1.5 T is presented, which is capable of imaging both 19F and 1H nuclei with higher SNR when compared to single-element alternatives. Microelectromechanical systems (MEMS) switches are utilized to provide broadband transmit-receive isolation over the frequency range of both nuclei. Coil channel isolation is demonstrated and MEMS switching performance with phantom imaging of both nuclei.
