✦ Synopsis
This work presents a new method for localized TI measurements, based upon the OSIRIS scheme. It relies on the use of a non-selective 180" pulse applied before the OSIRIS preparation cycle. The accuracy of the method has been verified with test tubes and in uiuo for two nuclei, 'H and 'w. The accuracy of the TI values is discussed, as well as possible applications of the inversion-recovery method to non-invasive in vivo p02 measurements.
