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
Diagnostic radiology techniques are generally noninvasive, 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
