1H-MRS (proton magnetic resonance spectroscopy) is a method for analyzing material components using the difference of the frequency (chemical shift) in magnetic resonance. 1H-MRS for human body is able to diagnose the clinical conditions by non-invasive analysis of materials in organs. However, the mechanical limitations and complexity in analyses prevented it from becoming popular as MRI (magnetic resonance imaging). Recently, an ideal environment for 1H-MRS is commonly available such as stronger magnetic field and improved software, yet we still lack common knowledges about 1H-MRS which makes whom plans to start it difficult. In this article, the principle, tips, clinical applications and spectrum evaluations were explained focusing on novice users.

The magnetic resonance imaging (MRI) is established as the imaging technique that is essential to the imaging of the central nervous system disease. Above all, the diffusion weighted image (DWI) is known as the tool which can diagnose acute ischemic stroke with high accuracy in a short time. DTI, an applied form of DWI, was devised as a technique to image the structure of the brain white matter. In clinical sites, this technique is used for pathologic elucidation such as the intracerebral tissue injury or mental disorder. Additionally, diffusion tensor tractography (DTT), which is a technique to build three-dimensional structure of the neural fiber tracts, is used for grasping the relations between a brain tumor and the fibers tract. Therefore, these techniques may be useful imaging tools in the central nerve region.

Treatment planning systems with highly accurate dose calculation algorithms such as Monte-Carlo method and linear Boltzmann transport equation are becoming popular thanks to a development of the computer technology. These algorithms use new concepts, dose-to-medium and dose-to-water. However, introducing these concepts can cause confusion in clinical sites. Basic knowledges about Monte-Carlo simulation and other corresponding algorithms were explained in this article such as the principles, the parameters and words of caution.
