The importance of magnetic resonance image in studies about interactive processes of organs and systems

Abstract

Magnetic resonance image (MRI) was developed in the 70’s and became a cornerstone for neuroscience. In MRI, the biological tissues are subjected to a magnetic field, which means that the hydrogen nuclei (protons) are targeted, vibrate on its axis, emit energy and generate images of various tissue types. The MRI technique is based on three steps: alignment, excitation and radiofrequency detection. The functional MRI is produced based on glycolysis peroxide. The technique of diffusion weighted imaging (DWI) exploits the differences of water diffusion properties and magnetic resonance of diffusion tensor imaging (DTI) enables in vivo study of fibrous tissue. These techniques have made possible the visualization of different physiological, biochemical, cellular and molecular processes to provide direct information about the interactive processes of organs and systems.
