Magnetic Resonance Imaging (MRI) and Spectroscopy Techniques

Definition

Magnetic Resonance Imaging (MRI) is a non-invasive imaging technique that uses powerful magnets and radio waves to produce detailed images of the organs and tissues within the body. Spectroscopy techniques, on the other hand, analyze the chemical composition of tissues by measuring the interaction between magnetic fields and atomic nuclei, providing insights into metabolic processes. Together, these techniques have become crucial tools in exercise physiology, helping to evaluate muscle health and function, as well as monitor physiological changes during exercise.
