Radiology, Diagnostic

Diagnostic radiology is the process of creating images of the body, its organs, and other internal structures with external radiation. Diagnostic radiology techniques include the use of x-ray tubes that emit radiation, radionuclides, ultrasonographic devices, and radiofrequency electromagnetic radiation.

Diagnostic radiology techniques are generally non-invasive, meaning the body is not entered with any equipment or cut open for imaging. However, certain procedures do combine diagnostic radiology techniques with minimally invasive procedures to diagnose and treat a condition. In addition, diagnostic radiology is often used to assist during minimally invasive surgery.

Many different diagnostic scans and procedures are also performed in nuclear medicine. Nuclear medicine utilizes small amounts of radioactive agents, such as thallium or technetium, to examine various organs and their structures. These scans are used to diagnose, manage, and treat medical disorders and diseases.
