Magnetic resonance spectroscopic imaging (MRSI) is a biomedical imaging tool that enables spatial mapping of metabolite signals in vivo. Dedicated software for MRSI data preprocessing, image reconstruction, visualization and simulation is vital to the development and routine application of MRSI but relatively few tools are available for this purpose. We present an open source toolbox in MATLAB for preprocessing, visualization and simulation of MRSI data. The processing toolbox includes functions for importing data, coil combination, B0 inhomogeneity correction, and non cartesian reconstruction, while the simulation toolbox can simulate MRSI acquisitions with arbitrary input k-space trajectories.
