✦ Synopsis

High longitudinal selectivity of the shifting multiplexing with spherical reference wave is proposed and demonstrated. A simpliÿed method based on wave optics is used for calculating the selectivity, and the result ÿts well the experimental measurement. Under the paraxial condition, a simple formula for the longitudinal selectivity is introduced. With use of an object lens with e ective NA = 0:817, we obtain that an FWHM of selectivity is as small as 1 m.

A new approach to volume-selected in vivo NMR spectroscopy uses two frequencyshifted sinc pulses, in conjunction with pulsed field gradients, to destroy the coherence of the unwanted signals. A hard u/2 pulse can then be used to read the z magnetization in the region of interest. This method is inde

## Abstract A new spectral bandwidth expansion technique for highspeed magnetic resonance spectroscopic imaging (MRSI) based on an echo‐planar technique is presented. This expansion can be achieved by spatial and chemical shift selective saturation without increasing the total measurement time. In
