摘要: The hybrid technique of projection-reconstruction echo-planar (PREP) imaging for obtaining chemical-shift images is demonstrated experimentally using a fluorine sample. which variation on (EPI) relies multipass procedure. It nevertheless quite efficient and consequently may be produced in few minutes. method produces 64 regions, each region mapped spatially by × pixels. time was just over 4 min. These chemical-shifted can straightforwardly added together to form an undistorted image the complete object. In addition spectrum extracted various unambiguously assigned spectral peaks.
