ABSTRACT:
A method of imaging flowing fluids, such as human blood, using nuclear magnetic resonance whereby an image of high resolution is obtained. First, nuclear spin is excited in a given slice plane of a sample disposed in a magnetostatic field. Then, phase disorder in a direction of a first field gradient due to the first step is compensated for and at least one 180.degree. RF pulse is applied. Next, the nuclear spin is again excited in the slice plane, after which at least first, second and third magnetic field gradients are applied to derive an output signal.
