## Abstract A new perfluorocarbon, PTBD (perfluoro‐2,2, 2′, 2′‐tetrameth‐yl‐4,4′‐bis(1, 3‐dioxolane)), is described for use in ^19^F MR imaging and spectroscopy. Two‐thirds of the molecular fluorine in PTBD resonates at a single frequency and can be imaged without the use of frequency‐selective spi
