Ultrahigh time resolution magnetic resonance is achieved in a flow-through device such as a microfluidic chip by imaging along the flow dimension. Position within the one-dimensional image may be related to time by the flow velocity. Thus, a time resolution corresponding to the one-dimensional image resolution is obtainable.
