I have the following question: given a known chemical shift $\delta$ between 2 tissue proton resonances and a MR image sequence with a total spin-echo sampling time of $t$ ms, what is the spatial shift in pixels in images acquired using a magnet with known magnetic field strength $B0$?

I think the first step is to work out the difference in frequency between the 2 tissue proton resonances will be given by $\Delta \omega = \gamma * B0 * \delta$ but I don't know how to relate this to the pixels or the total sampling time.

Thanks!

The sampling time will allow you to deduce the total bandwidth, if you know the resolution of the image you can then work out the bandwidth/per pixel and then calculating your shift ought to be trivial.
