✦ 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.

This work presents a new method allowing localized T2 measurements, based upon the OSIRIS scheme. A train of 180" pulses is applied after the OSIRIS preparation cycle, recording directly the transverse magnetization decay. The method was verified for two nuclei, 'H and '9, with phantoms and in uiuo

## Abstract TOMROP is a multiple readout single inversion‐recovery sequence which may potentially allow the measurement of multi‐exponential T~1~ recoveries __in vivo__ by NMR imaging. It is shown that several important modifications must be made to this sequence to permit T~1~ to be measured accur
