Magnetic Resonance Spectroscopy (MRS) data were usually acquired with single voxel spectroscopy techniques (SVS), which is used to access metabolites concentrations from a predefined volume of interest (VOI). Currently, MRS has been linked to fMRI studies to access metabolic information. Therefore, it’s important to define the VOI on standard space (template) and transform the predefined VOI from standard space to subject space for each MRS scan. In this study, we developed a tool to guide the definition of VOI on template before MRS scan then automatically calculate VOI in subject space.
