Abstract: Describes a new nuclear magnetic resonance (NMR) imaging technique which the authors call 'spin warp imaging' and gives examples of its application to human whole-body imaging. The apparatus is based on a four-coil, air cored magnet (made by the Oxford Instrument Company) capable of accepting the whole human body. The magnet produces a static field of 0.04 T giving a proton NMR frequency of 1.7 MHz. The maximum field inhomogeneity is about 6*10-4 at a radius of 0.23 m, approximately twice the amount theoretically attainable with this configuration. The pulse sequence used is shown.

TL;DR: In this article, a nuclear magnetic resonance (NMR) machine capable of producing tomographic sections of the whole human body in vivo has been constructed based on a four coil, air-core electromagnet producing a field of 0.04 T which corresponds to a proton NMR frequency of 1.7 MHz.

TL;DR: The design of a double inversion recovery (DIR) sequence, to image selectively grey or white brain matter, is described and was found to give clear delineation of the cerebral cortex.

TL;DR: In this article, a workshop was held to review the current status of DCE-MRI and to provide recommendations on how the technique can best be used for early stage clinical trials.

TL;DR: This work extended previously described methodology for in vivo T1 measurement to two‐dimensional (2D), fast low‐angle shot (FLASH), which requires computational modeling of slice‐selective radiofrequency (RF) excitation to correct for nonrectangular slice profiles.
