The local B0 field within red bone marrow is very inhomogeneous and common localized 1H magnetic resonance spectroscopy (MRS) can only give two rough peaks (water and fat peak). Other fat peaks which may contain more information for clinic diagnosis are not well resolved. We proposed a novel localized 1H MRS method based on intermolecular double quantum coherence technique to enhance the resolution of red bone marrow spectrum. Contrast to common MRS, six additional fat peaks including monounsaturated (5.3 ppm) and polyunsaturated (3.0 ppm) fat peaks are well resolved.
