Multisliced ultrafast 2D relaxometry

The flipped longitudinal polarization sequence

“…4B shows the lower amplitude profiles on a magnified scale. The deviation in the profile from the ideal shape of two adjacent rectangles is mainly a consequence of B 0 field inhomogeneity arising from an unshimmed magnet [6]. Fig.…”

Ultrafast T1–T2 relaxometry using FLOP sequences

“…(10) and (13) for each component peak in the T 2 -spectrum and the discrete T 1 -T 2 -spectrum to be constructed. Fig.…”

“…However the development of routine clinical T 1 -T 2 relaxometry requires that it is both fast and volume-selective. A number of approaches to fast T 1 -T 2 data acquisition have been proposed, including reducing the recovery delay [8] and multislicing [10]. We have also proposed a number of strategies for volume-selective T 1 -T 2 relaxometry [11].…”

Spatially-resolved 1H NMR relaxation-exchange measurements in heterogeneous media

“…Concurrently, Venturi and Hills introduced the first spatially-localised experiment (called SPACE-), which combined volume-selective (i.e., 3D imaging) methods with low-field 2D relaxometry [30]. The authors then exploited multi-slicing methods for single-shot acquisition of standard spectra in homogeneous systems, where each slice was associated with an inversion recovery time increment [31]; the ultra-fast approach was further extended by Telkki and co-workers to diffusion-relaxation ( ) measurements [32]. Zhang and Blümich [33] developed the first spatially-resolved correlation measurements based on the use of a 2D phaseencode imaging approach, and Balcom and co-workers [34] have implemented slice-selective 1D MRI measurements.…”
