Biomedical research has a profound impact on the medical field, and biomedical applications have promoted the development of early disease detection and precision treatment. Magnetic resonance spectroscopy can be used to study metabolic processes in organisms, including brain metabolism, muscle metabolism and tumor metabolism, and help understand the development and treatment of diseases. In addition, neurological diseases, cardiovascular diseases, early cancer detection and quantitative tumor characteristics can also be studied in order to better understand disease mechanisms and develop new treatments. Biomedical research is helpful to provide evidence for clinical decision-making, promote early intervention and treatment, improve treatment strategies, and promote the development of medical research.
