Radiologic Technology encompasses a number of imaging and therapeutic specialties used in the delivery of medical care. All use some form of energy or radiation to obtain diagnostic images or to conduct treatment. They are:

  • Radiography
  • Nuclear Medicine Technology
  • Radiation Therapy
  • Diagnostic Medical Sonography
  • Magnetic Resonance Imaging
  • Mammography
  • Computed Tomography
  • Bone Densitometry
  • Cardiac-Interventional Radiography
  • Vascular-Interventional Radiography


The following link to the American Society of Radiologic Technologists will take you to an excellent summation of the role Radiologic Technologists have in patient care and the services they provide.

Radiologic technologists held about 229,300 jobs in 2012. About 61 percent of all jobs were in hospitals. Most other jobs were in offices of physicians; medical and diagnostic laboratories, including diagnostic imaging centers; and outpatient care centers.

Employment of radiologic technologists is expected to increase by about 21 percent from 2012 to 2022, faster than the average for all occupations.(Occupational Outlook Handbook 2015 edition) As the population grows and ages, there will be an increasing demand for diagnostic imaging. With age comes increased incidence of illness and injury, which often requires diagnostic imaging for diagnosis. In addition to diagnosis, diagnostic imaging is used to monitor the progress of disease treatment.
