  Magnetic Resonance Imaging (MRI) may be a non-invasive imaging technology that produces three dimensional detailed anatomical images. It is often used for disease detection, diagnosis, and treatment monitoring. It is supported sophisticated technology that excites and detects the change within the direction of the rotational axis of protons found within the water that creates up living tissues. MRIs employ powerful magnets which produce a robust magnetic flux that forces protons within the body to align thereupon field. When a radiofrequency current is then pulsed through the patient, the protons are stimulated, and spin of equilibrium, straining against the pull of the magnetic flux . When the radiofrequency field is turned off, the MRI sensors are ready to detect the energy released because the protons realign with the magnetic flux . The time it takes for the protons to realign with the magnetic flux , also because the amount of energy released, changes counting on the environment and therefore the chemical nature of the molecules. Physicians are ready to tell the difference between various sorts of tissues supported these magnetic properties. To obtain an MRI image, a patient is placed inside an outsized magnet and must remain very still during the imaging process so as to not blur the image. Contrast agents (often containing the element Gadolinium) could also be given to a patient intravenously before or during the MRI to extend the speed at which protons realign with the magnetic flux . The faster the protons realign, the brighter the image. Top Journals Includes Magnetic Resonance in Medicine, Magnetic Resonance Imaging (journal), NMR in Biomedicine
