METHOD OF LIMITING THE REGION FOR MAGNETIC RESONANCE IMAGING.

摘要

A magnetic resonance imaging method wherein the limitation of the region is conducted by a pulse sequence instead of using an electric filter comprises: a step for measuring spin echo signals from an object to be inspected using a pulse sequence of the Fourier transform method; a step for measuring spin echo signals from the object to be inspected using a pulse sequence to which are added selective 180 DEG +/- X pulse and 180 DEG +/- Y pulse after 180 DEG pulses in the pulse sequence of the Fourier transform method and of which the integration of a gradient magnetic field for selection is 0; and a step for reconstituting the image based on the sum or the difference of the spin echo signals measured by using these two sequences.
