The refocusing property of the oscillating gradient can be exploited for generation of gradient echoes. 

Imaging with multi-pulse line narrowing has been realized in different variants. These include time-invariant gradients, oscillating gradients, pulsed gradients, and CRAMPS. Each of these variants is addressed in the following. 

With oscillating gradients, echo times could be reduced from 2 ms to 128 xs on a solid-state imaging system. When echo times are as short as this, many polymers can be imaged by Fourier techniques adapted to oscillating gradients...
