# Importing multiple DICOM files to be annotated and displayed at once

You may group together DICOM files and upload them to Hub as a single asset, where each DICOM can be annotated individually.

You may upload such multi-DICOM assets using the *Cloud Import* method outlined below.

## Uploading Multi-DICOM Assets

Prepare a JSON like the following, where each URL points to a DICOM you'd like to include in the asset, for a maximum of 24 DICOMs.

{% hint style="info" %}
This functionality is only available in projects created on or after the 9th of March 2025.
{% endhint %}

The following JSON will import an assets containing four DICOMs:

```json
[
    {
        "externalId":"SingleFrame_MultiFile_DCM",
        "dataset": [
          "https://angohub-docs-assets.s3.eu-central-1.amazonaws.com/demo-assets/single_page.dcm",
          "https://angohub-docs-assets.s3.eu-central-1.amazonaws.com/demo-assets/MR000000.dcm",
          "https://angohub-docs-assets.s3.eu-central-1.amazonaws.com/demo-assets/single_page.dcm",
          "https://angohub-docs-assets.s3.eu-central-1.amazonaws.com/demo-assets/MR000000.dcm"
        ]
    }
]
```

This asset will appear like so (blurred for privacy):

Ango Hub will automatically adjust the view depending on the number of DICOM files in the dataset.

From your project dashboard, go to the *Assets* tab and click on *Add Data*. Then, enter the *Cloud Storage* section and drag and drop your JSON on the file upload field. Then, press on *Upload*. Your multi-DICOM asset(s) will be uploaded.

If your DICOM files are in a private bucket, ensure you select the appropriate [storage integration](/data/storages.md) from the list on the left.
