## Abstract A novel technique is presented to measure __in vivo__ simulataneously oxygen tension and temperature using ^19^F NMR spectroscopy of perfluorocarbon. This work examines the variation with oxygen tension (pO~2~) and temperature of the individual spin lattice relaxation rates (__R__~1~) o

The application of an improved imaging sequence for i9F NMR imaging in perlhtorotributylamine is discussed and the results of phantom studies are reported. Frequency-selective excitation by a l-3-3-1 hard pulse sequence and a short echo time are used to increase the signal-to-noise ratio. In this wa
Perfluorinated blood substitutes can be detected by I9F NMR in vivo in small concentrations. Reactive hyperemia was induced in rat leg by the transient application of a tourniquet, causing a 50% increase in I9F NMR signal. These results show that this method can be used to monitor the kinetics of ti
## Abstract The application of an ultraโfast low angle RARE technique for the ^19^F imaging of perfluorocarbons (PFCs) used as temporary blood substitutes is described. This sequence is attractive for fast ^19^F imaging studies that measure the biodistribution of PFCs __in vivo__, due to its high s
## Abstract This work examines the variation with oxygen tension (__p__O~2~) of the individual spinโlattice relaxation times (T~I~) of the ^19^F resonances of the perfluorocarbon emulsion OxyโpherolโET (FCโ43). A linear relationship between 1/T~1~ and __p__O~2~ has been confirmed for all four reson
