Radiography

Specialty of Radiology

What is radiography?

Radiography is an imaging technique used to provide images of the tissues, organs and bones inside the human body. There are two types of radiographers: diagnostic and therapeutic. A diagnostic radiographer takes images of the insides of patients’ bodies to diagnose injury, illness and disease. A therapeutic radiographer is an allied health professional who has undergone specific training to be able to deliver radiotherapy for patients undergoing treatment for cancer. A radiographer is also not to be confused as a radiologist as although they work closely together, they are different physicians.

What’s the difference between a radiologist and radiographer?

Radiographers are the ones to operate the tools and equipment, whilst radiologists analyse and interpret the images, or treat patients with radioactive materials. Radiology is a branch of medicine and radiography is the type of technology radiologists employ to do their jobs.

What equipment does a radiographer use?

Radiographers operate the following equipment:

  • X-rays – to look through tissues to examine bones and cavities
  • CT scan (computed tomography) – provides views of cross-sections of the body
  • MRI (magnetic resonance imaging) – builds a 2D or 3D map of different tissues
  • Ultrasound – to check circulation and examine the heart
  • Nuclear medicine imaging
