✦ Synopsis

A method of chemical-shift imaging is described using the invariance of chemical shifts to changes in magnetic field gradients used for frequency encoding of position in imaging. This enables separation of the effects on the observed signal of chemical shift from the effects of different positions along the imaging gradient when the signal is observed with different gradients. A simple implementation for a two-line spectrum is presented using signals observed with normal and reversed imaging gradients. This is used to create "fat" and "water" images of the thigh. 0 1985 Academic press. Inc.

## Abstract Single‐shot echo‐planar imaging (EPI) is an important method for MRI of the brain. A method has been developed to double the resolution of EPI in the phase‐encode direction, without requiring increases in the maximum gradient amplitude or slew rate. The new approach is based on an EPI i

Magnetic resonance imaging (MRI) with chemical shift resolution is a recent extension of MRI and it provides information about species resolved molecular transport on the macroscopic scale in complex systems. In this contribution, we show that by using this novel method, one can predict the behavior
