Elimination of susceptibility distortions and reduction of diffusion attenuation in NMR microscopy by line-narrowed 2DFT.

NMR imaging at high field strengths is adversely affected by magnetic susceptibility variations within the specimen. This is especially true in NMR microscopy. We present results using a line-narrowed imaging sequence which overcomes the image distortions associated with the frequency encoded readout method. Signal attenuation due to diffusion in static magnetic field gradients is also reduced.
