magnetic resonance imaging
a medical diagnostic procedure utilizing the phenomenon of nuclear magnetic resonance to generate images of internal parts of the body It depends on the differential absorption of electromagnetic radiation by different types of living tissue in a magnetic field It is complementary to X ray imaging in that the softer tissue show more prominently in magnetic resonance images rather than bone as with X rays It is a non invasive procedure allowing such images to be obtained without penetration of the tissue by objects It is abbreviated MRI As with computerized tomography the results are usually presented as images of sequential planar sections of that part of the body of concern to the physician...
nuclear magnetic resonance
The specific absorption and re emission of electromagnetic radiation at characteristic wavelengths by atomic nuclei in a magnetic field It is abbreviated NMR The wavelength of the radiation absorbed depends on the type of nucleus the intensity of the magnetic field and the local chemical environment in which the nucleus resides It is the latter effect called the chemical shift by which atoms of specific elements in different chemical compounds show a different resonance frequency which gives rise to the greatest utility of this phenomenon in analyzing the chemical structure of substances Similar effects of the chemical environment permit the discrimination of different types of living tissue by virtue of their different chemical composition thus permitting utilization of the phenomenon in medical diagnostic instruments especially for magnetic resonance imaging...
