This work presents a numerical approach to optimizing sequences with composite pulses for the pure NQR of a spin I = 32 powder sample. The calculations are based on a formalism developed in a previous paper, which allows a fast powder-averaging procedure to be implemented. The framework of the Cayle
The purpose of this study was to assess gradient magnetic-field-induced acoustic noise levels associated with the use of echo planar imaging (EPI) and three-dimensional fast spin echo (3D-FSE) pulse sequences. Acoustic noise measurements were obtained from two different high field-strength MR system
## Abstract Novel pulse sequences incorporating the double pulsed field gradient spinβecho technique are presented that have particular use in identifying macromolecular bound water. The use of these sequences is illustrated using ribonuclease T~1~. Five amide protons crossβrelaxing with bound wate
