Robust water suppression in volumetric whole-brain 1H MRSI can be difficult to achieve using conventional acquisition-based or post-processing methods. In this study is examined a new approach to water removal by subtraction of an interleaved water reference SI method. Results indicate that some improvement in spectral baselines can be achieved, resulting in improved spectral fitting of resonances close to water. In addition, some reduction of the residual subcutaneous lipid signal can be achieved.
