Abstract
Inadequate signal-to-noise ratio is a major factor limiting applications of magnetic resonance microscopy. The ``Diffusion En-
hancement of Signal and Resolution'' (DESIRE) scheme promises potential sensitivity enhancements of between one and three or-
ders of magnitude, but images using this mechanism have not been shown to date. Here, we report the first images obtained using
the DESIRE method, and obtain excellent agreement between numerical simulations and experimental data with signal-to-noise
enhancements of close to one order of magnitude.
