# Scans Reports
#### Access body composition and health reports for user scans.
Use these endpoints to fetch derived metrics such as body fat, lean mass, circumferences, metabolic outputs and consolidated health reports for each scan. Typical use cases include powering health dashboards, progress tracking, coaching experiences and downstream analytics.
All Scans - Reports endpoints require the following headers:
```http
accept: application/json;v=1
authorization: Bearer {{API_KEY}}
content-type: application/json
```
Replace `{{API_KEY}}` with your Prism API key for the selected environment.
## Get body measurements of a scan.
> \
> This operation provides the detailed \*\*body measurements\*\* derived from a specific \*\*scan\*\*.\
> \
> Optionally, you can use the \`unit-system\` query parameter to receive measurements in \*\*metric\*\* or \*\*imperial\*\* units.
