rephasing

An MRI term for the process of returning out-of-phase magnetic moments back into phase coherence, which is caused either by rapidly reversing a magnetic gradient (field echo) or by applying a 180º radio frequency pulse (spin echo), the latter of which effectively cancels out the spurious T2 information from the signal.
