What Is Radiography?

Radiography uses the science of radiation to produce images of tissues and organs. Read on to learn more about radiography and those who work within the field. Schools offering Cardiovascular Sonography degrees can also be found in these popular choices.


Radiography is used by medical professionals to diagnose and treat medical conditions. The diagnostic side of radiography uses specialized equipment to create images, such as x-rays, that show the inside of the human body. X-rays can be recorded on film or as a computerized image. Radiography can also be used to treat internal malignancies like tumors. A doctor who specializes in this area is called a radiologist, while an assistant is referred as a radiologic technologist.

Radiologic Technologists

According to the American Society of Radiologic Technologists (ASRT), a radiologic technologist is part of a medical personnel team that is responsible for taking diagnostic images and performing radiation therapy treatments. These professionals are trained in a number of core areas that are important to radiography, including the following:

  • Patient positioning
  • Anatomy
  • Equipment protocols
  • Radiation safety
  • Radiation protection
  • Patient care


Another important part of the radiography medical personnel team is the radiologist. A radiologist is a medical doctor and typically works in a diagnostic imaging department. Many radiologist specialize a sub-specialties of radiography.

Specializations of Radiography

Radiologists and radiologic technologists may choose to specialize in a specific area of radiography. The following is a list of some specializations within the field:

  • Angiography
  • Simple x-ray
  • Bone densitometry
  • Fluoroscopy
  • Magnetic resonance imaging (MRI)
  • Mammography
  • Computed tomography (CT)
  • Cardiovascular-interventional radiography

Radiography Job Outlook

According to the Bureau of Labor Statistics (BLS), other key jobs within the field of radiography include cardiovascular technologists and technicians, diagnostic medical sonographers and nuclear medicine technologists. The BLS predicts job availability for radiologic and MRI technicians is expected to increase by 21% over the 2012-2022 decade, and opportunities for physicians and surgeons, including radiologists, are likely to expand by 18% over that period of time. Job seekers who have experience with more than one diagnostic imaging tool will have the best chances for employment.
