Non proton and metabolism imaging Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to form pictures of the anatomy and the physiological processes of the body. MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to generate images of the organs in the body. MRI does not involve X-rays or the use of ionizing radiation, which distinguishes it from CT and PET scans The Na-MRI technique provides a measure of the tissue sodium concentration (TSC), which represents an average of the Na concentration in the intra- and extra-cellular tissue compartments weighted by their respective volume fractions. For example, in brain tissue the TSC is typically +. , , How can sodium MRI techniques help us understand acute. Dixon MRI technique.
