A radiologist is a medical professional who specialises in using medical imaging technologies to diagnose and treat injury and disease.

Diagnostic radiologists use medical imaging techniques to diagnose a disease or condition. Interventional radiologists use medical imaging techniques to diagnose and treat disease. Therapeutic radiologists (known as radiation oncologists) use radiation to treat diseases such as cancer.
