Magnetic resonance imaging technologists (MRI technologists) use magnetic fields, radiofrequency pulses and computers to generate cross-sectional images of the human anatomy. MRI technology is used mainly to view images of the soft tissues within the body such as areas within the brain, knees, shoulders, scar tissue, etc. An MRI technologist will place a patient inside a special machine that exposes the patient?s body to an immense magnetic force. This force causes the hydrogen atoms within a patient to align with the magnetic field. The MRI technologist will then apply a radiofrequency pulse that causes the atoms to spin out of alignment. When the pulse is stopped, the atoms will then return to their proper alignment. As they do so, the different atoms give off different signals that are measured by computers to generate images of the internal anatomy. MRI technology plays a major role in doing such things as detecting tumors within the brain and mapping out scar tissue. The majority of MRI technologists work in hospital settings. However, they also work in surgery centers, imaging centers, physician?s offices and clinics.
Educational Requirements and Resources After initial registration in one of the above areas, individuals must then pass an advanced level registration examination in magnetic resonance imaging given by a nationally recognized organization such as The American Registry of Radiologic Technologists. Individuals are eligible to take the examination only after completing a minimum number of clinical training hours in areas pertaining to magnetic resonance imaging technology. After completion of clinical requirements, an individual may then take the examination. Upon passing the examination, an individual becomes a registered magnetic resonance imaging technologist. For additional information on magnetic resonance imaging technologists, please visit the American Society of Radiologic Technologists. |
