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: 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:

```
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>
```

The question should be specific, self-contained, and written in natural language.
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.
