Radiology refers to the study and application of imaging technology. A physician working within the field of radiology is called a radiographer, and their expertise may extend to diagnosing and treating disease. Radiographers specialise in the use of a wide range of advanced imaging technologies to perform their specific role.

This imaging technology can include:

  • Ultrasounds
  • Computed Tomography (CT)
  • Nuclear Medicine
  • Positron Emission Tomography (PET)
  • Magnetic Resonance Imaging (MRI)
  • Projectional Radiography
  • Fluroscopy

Each type of medical imaging has its own benefits and restrictions, and typically, radiology is a minimally invasive technique to obtain information about the internal condition of different body parts. For lungs, heart and skeletal images, projection radiography is still the most widely used technique because of its speed and low cost. Projection radiography uses ionising radiation to penetrate tissue and create diagnostic images.

Many other imaging technology uses the technique of ionising radiation to achieve different purposes. A CT scan, for example, uses ionising radiation along with computing algorithms to produce cross-sectional images. Not all medical imaging techniques use ionising radiation, though, and ultrasound and MRI are prime example. Ultrasound uses high-frequency sound waves while MRI use strong magnetic fields.

Radiographers can assist in areas as vast as trauma injuries such as broken bones to pregnancy or surgery. If you need to find a local radiology clinic, look to the specialists at Call today to find out more information from a physician specialising in the field of radiology.
