In this work, we proposed a new strategy to identify the source of potential artifacts in single voxel 1H MRS by taking into account the intrinsic B0 field gradients in the human brain. We mapped the intrinsic gradient fields inside the human head to assess the level of signal crushing of each pathway in the entire field of view of the receiver coil. This will enable subject and location specific design of optimal crusher gradient scheme in SV MRS.
