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.
In terms of education, this position requires an individual be a graduate of an
accredited educational program in radiologic technology, radiation therapy or
nuclear medicine. After the education process is complete, an individual must then
become a registered technologist in one of the following areas: radiologic
technology, radiation therapy, or nuclear medicine. (For specific educational
requirements, registration requirements, and a listing of educational
programs in the state of Ohio for each of these areas, please click on one or all
of the following: Radiologic Technologist
(Radiographer), Radiation Therapist,
Nuclear Medicine Techologist).
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.
