SUSCEPTIBILITY, FIELD INHOMOGENEITY, AND CHEMICAL SHIFT-CORRECTED NMRMICROSCOPY - APPLICATION TO THE HUMAN FINGER IN-VIVO

Spectroscopic proton image data recorded with the aid of a gradient-ec ho spectroscopic imaging pulse sequence are reported, A postdetection processing method is suggested which permits correction of artifacts d ue to inhomogeneity, susceptibility, and chemical-shift resonance offs ets, That is, apart from the spectral information available in this wa y, better spatial resolutions can be achieved, The method is demonstra ted by resonance-offset corrected images of the human finger in vivo, Moreover, resonance-line selective and spectroscopically resolved diff usion-weighted images and diffusivity maps rendered with the aid of th e same postdetection procedure are shown.
