Medical News Today: What does a radiologist do?

There are several different specialties of radiology, including:

Diagnostic radiology

Diagnostic radiologists use medical imaging to diagnose and treat diseases. They can use a variety of different imaging methods, such as:

  • X-rays
  • radionuclides
  • ultrasounds
  • electromagnetic radiation

Interventional radiology

Interventional radiologists use medical imaging to provide therapy to people with noncancerous conditions.

For example, an interventional radiologist might use medical imaging to support a surgical procedure.

This imaging can make surgical procedures safer and lead to faster recovery times. Interventional radiologists typically work on keyhole surgery.

Keyhole surgery involves making small cuts instead of larger ones and using tiny cameras to see inside the body.

Radiation oncology

A radiation oncologist uses radiation-based therapy to treat cancer. This therapy involves the use of high energy radiation to damage cancer cells, which stops them from spreading further.

It can help reduce symptoms or, in some cases, cure the condition entirely.

Medical physics

Medical physicists use their understanding of physics to support the practice of medicine in different ways.

For example, they can advise on and deliver the technical aspects of medical imaging to ensure the safety of patients and the effectiveness of the results.

Some medical physicists are also researchers and play a role in developing new medical technology. Medical physicists have developed many devices that doctors commonly use today, such as magnetic resonance imaging (MRI).
