The present invention relates to a phantom for evaluating the performance of a magnetic resonance imaging apparatus for proton magnetic resonance single voxel spectroscopy. Proton magnetic resonance single voxel spectroscopy is a type of magnetic resonance spectroscopy (MRS) which enables measurement of biochemical variation generated by penetration of metabolite into a bio-tissue through a continuous, repetitive, and non-invasive method using the magnetic resonance imaging apparatus. A standard for qualifying the evaluation is necessary in doing the performance evaluation on the spectroscopic resolution of the magnetic resonance imaging apparatus and shimming degree of magnetic field related to the MRS. The phantom for evaluating the performance of the magnetic resonance spectroscopy imaging (MRSI) based on the present invention can perform the function. There is an aqueous solution in which each metabolite distributed in the human brain is diluted in an inner container of janggu shape, which is placed inside the phantom, so it is possible to know whether the spectrum of each material in the MRSI obtained from the human brain properly matches that obtained from the phantom. In addition, because the inner container of the phantom forms the janggu shape or layered dumbbell shape, the position accuracy of VOI (volume of interest) and quantitative accuracy of metabolite can be measured by controlling the amount of metabolite which is contained in the voxel of each layer.
