ABSTRACT:
A method of investigating a body by nuclear magnetic resonance comprising preferentially exciting resonance in a slice of the body, applying a magnetic field to the body having first and second gradients (Gx, Gy) in different directions in the slice with both the gradients being periodically reversed at regular intervals, detecting the free induction decay signals occurring when the gradients are applied and processing the detected signals to retrieve data. The method is an adaptation of the echo-planar technique suitable for obtaining chemical shift information.
