    • A nuclear magnetic resonance imaging method and apparatus, capable of obtaining images with high spatial resolution arid S/N ratio, reducing the influence of the inhomogeneity of the static magnetic field and the chemical shift artifacts, and improving the contrast in the T.sub.2 enhanced image and T.sub.1 enhanced image. The imaging uses the pulse sequence, including: application of RF pulses and slicing gradient magnetic field for exciting a desired region of the body to be examined; application of reading gradient magnetic fields which regularly fluctuate between a negative value and a positive value; application of initial phase encoding gradient magnetic field before the reading gradient magnetic field is applied; application of a predetermined pulse shaped phase encoding gradient magnetic field every time the reading gradient magnetic field changes polarity; and collection of the echo signals emitted from the desired region every time the reading gradient magnetic field changes polarity. This pulse sequence is repeated while sequentially changing a setting of the initial phase encoding gradient magnetic field applied.
