In in vivo NMR study, inhomogeneous line broadening due to magnetic susceptibility gradients and intensive water signal often leads to severe spectral peak overlapping and weak signal obstructing. In this abstract, a new pulse sequence based on intermolecular single-quantum coherences (iSQC) was presented for high-resolution spectra from biological tissues. Several heterogeneous biological samples were measured to test the feasibility of the pulse sequence. The experimental results indicate that the method is a useful tool of high-resolution MRS for heterogeneous biological samples.
