| Attaching a radionuclide to a chemical and following its path in the body | tagging |
| Radionuclides are used as tags, or labels, attached to chemicals and followed as they travel through the body | tracer studies |
| Handheld device that sends and receives ultrasound signals | transducer |
| Diagnostic technique that projects and retrieves high-frequency sound waves as they echo off parts of the body. | ultrasonography |
