# Nuclear Medicine - Radionuclide Imaging

<mark style="color:$danger;">**This Editorial Guide is used for Education Purposes Only. It is used in the Authoring Courses and Certifications. It is based on the January 2026 Editorial Guide.**</mark>

Nuclear medicine imaging uses radionuclides or radioisotopes.

## Radionuclide scan

* FSN: Radionuclide scan of X (procedure)
* PT: Radionuclide scan of X
* SYN: Radioisotope scan of X
  * For example,
    * 710313004 | Radionuclide scan of peritoneal cavity (procedure)|
      * FSN: Radionuclide scan of peritoneal cavity (procedure)
      * PT: Radionuclide scan of peritoneal cavity
      * SYN: Radioisotope scan of peritoneal cavity

## Radionuclide scan using isotopes (with other agents)

* FSN: Radionuclide scan of X using Y (procedure)
* PT: Radionuclide scan of X using Y
* SYN: Radioisotope scan of X using Y
  * For example,
    * 710312009 | Radionuclide scan of perfusion of liver using technetium Tc^99m^ aggregated albumin (procedure)|
      * FSN: Radionuclide scan of perfusion of liver using technetium Tc^99m^ aggregated albumin (procedure)
      * PT: Radionuclide scan of perfusion of liver using technetium Tc^99m^ aggregated albumin
      * SYN: Radioisotope scan of perfusion of liver using technetium Tc^99m^ aggregated albumin

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.snomed.org/education/snomed-ct-education-editorial-guide/readme/authoring/domain-specific-modeling/procedure/index-1/index/nuclear-medicine-radionuclide-imaging.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
