## Abstract Determination of neurological pathology in white matter disease can be made in a semiquantitative way from __T__~1~β or __T__~2~βweighted images. A higher level of quantification based on measured __T__~1~ or __T__~2~ values has been either limited to specific regions of interest or to
The conventional stimulated-echo NMR sequence only measures the longitudinal component while discarding the transverse component, after tipping up the prepared magnetization. This transverse magnetization can be used to measure a spin echo, in addition to the stimulated echo. Two-dimensional single-
The application of solid echoes to the nuclear magnetic resonance (NMR) imaging of short Tz materials is demonstrated by means of two-dimensional ("F) images. A closed-form, exact and generally applicable expression for solid echo imaging is derived and a procedure for on-the-fly data analysis given
## Abstract The hybrid projection reconstruction (PR) imaging provides high temporal resolution through an undersampled PR acquisition for the inβplane dimensions and Cartesian slice encoding for the throughβplane dimension. The undersampling of projection data introduces streak artifact, which may
## Abstract We measure the velocity distribution of slow fluid flow in model systems using stimulated echoes and velocity phase encoding. We show velocity images of slow coherent flow with velocities of the order of 0.1 mm/s which is slower than can be obtained by the bolusβtracking method. The edd
