## Abstract Optimization of inversionβrecovery (IR) measurements of __T__~__1__~ relaxation times has focused on the efficiency of __T__~__1__~ estimation (precision per unit time), without explicit consideration of the total experimental time. With the modified fast IR method, the repetition time
## Abstract Inversion recovery sequences that vary the inversion time (__t__~__i__~) have been employed to determine __T__~1~ and, more recently, quantitative magnetization transfer parameters. Specifically, in previous work, the inversion recovery pulse sequences varied __t__~__i__~ only while mai
## Abstract A new flow suppression method has been proposed for the acquisition of bloodβsuppressed (blackβblood) images in combination with administration of a positive contrast agent. The technique employs the quadruple inversionβrecovery (QIR) preparative pulse sequence, which consists of two do
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 accurac
Multislice SE-or IR-sequences with different TRand T,-times, respectively, are often used, to determine Tland T,-values for tissue characterisation. To investigate the perturbating influence of the sequential excitation in multislice technique, we measured the signal intensities and calculated the T
