At first glance, this equation doesn’t seem to grant much wisdom to anyone about anything.

WebJust like in radio, bandwidth refers to the range of frequencies that a receiver listens to. Remember than in MRI, the frequencies encode one spatial dimension (for sake of discussion, the x-axis). (Of course, these are on top of the 'carrier frequency' which is the precession rate of a proton in the main magnetic field B 0 as given by the Larmor equation.)
