Abstract
An NMR imaging method and apparatus of the type in which a 180-degree RF pulse is applied to generate a spin echo after the selective excitation of a spin by a 90-degree RF pulse. A dummy gradient field, which has the same direction and intensity as those of a gradient field to be applied when the spin echo is observed, is applied between said 90-degree RF pulse and said 180-degree RF pulse so that the instant of starting the application of the gradient field for signal observation is advanced to the extent corresponding to said dummy gradient field.
