Localized T1 measurements using an inversion-recovery OSIRIS method.
This work presents a new method for localized T1 measurements, based upon the OSIRIS scheme. It relies on the use of a non-selective 180 degrees pulse applied before the OSIRIS preparation cycle. The accuracy of the method has been verified with test tubes and in vivo for two nuclei, 1H and 19F. The accuracy of the T1 values is discussed, as well as possible applications of the inversion-recovery method to non-invasive in vivo pO2 measurements.
