-                        <p>
-                            NCI Imaging Data Commons (IDC) is a cloud-based repository of publicly available cancer
-                            imaging data co-located with the analysis and exploration tools and resources. IDC is a node
-                            within the broader NCI <a href="https://datacommons.cancer.gov/"
-                            target="_blank" rel="noreferrer nofollow">Cancer Research Data Commons (CRDC)</a> infrastructure that provides
-                            secure access to a large, comprehensive, and expanding collection of cancer research data.
-                            All data hosted by IDC will be available publicly. The current content of IDC is populated
-                            using the radiology collections from <a class="external-link" href="" url="https://www.cancerimagingarchive.net/"
-                            data-toggle="modal" data-target="#external-web-warning">The Cancer Imaging Archive (TCIA) <i class="fa-solid fa-external-link external-link-icon" aria-hidden="true"></i></a>, as well as data
-                            collected by other major NCI initiatives, such as TCGA, CPTAC, NLST, and HTAN. IDC does not
-                            perform de-identification of images but will accept data de-identified by TCIA or other Data
-                            Coordinating Centers that are approved by NCI Security.
-                        </p>
-                        <p>
-                            IDC provides access to the data standardized using the <a class="external-link" href="" url="https://www.dicomstandard.org/"
-                            data-toggle="modal" data-target="#external-web-warning">Digital Imaging and Communication in Medicine (DICOM) <i class="fa-solid fa-external-link external-link-icon" aria-hidden="true"></i></a>
-                            standard. IDC collaborates with the projects generating the data to
-                            harmonize alternative formats into DICOM representation. Its content includes not only
-                            images, but also image annotations and analysis results, and is linked using common
-                            identifiers to the other types of cancer data, such as proteomics and genomics datasets in
-                            the <a href="https://datacommons.cancer.gov/" target="_blank" rel="noreferrer nofollow">
-                            Cancer Research Data Commons (CRDC)</a>. Access to the data is supported using standard
-                            interfaces. Given the IDC's role as an imaging data science platform, a major focus is on
-                            establishing best practices for imaging research. In this regard, a key role of IDC is in
-                            preparing and adapting commonly used tools for image analysis to be run on cloud
-                            environments with IDC-hosted datasets. Summarized derived data from analyses previously
-                            run will be associated with imaging data on IDC for ease of use by the research community.

-                        <h5>Data Types</h5>
-                        <p>
-                            IDC contains various types of images and image-derived data harmonized using the DICOM standard.
-                            As of October 2022, IDC contains the following types of images:
-                            <ul>
-                                <li>Clinical and preclinical imaging</li>
-                                <li>Radiological images (e.g., CT, MRI, PET)</li>
-                                <li>Digital pathology images</li>
-                                <li>Multispectral microscopy images</li>
-                                <li>Image annotations (e.g., planar and volumetric, regions of interest)</li>
-                                <li>Parametric maps derived from images (e.g., perfusion and diffusion maps)</li>
-                                <li>Measurements derived from the images (e.g., radiomics features for the annotated regions of interest)</li>
-                                <li>Expert assessments of the image findings (e.g., qualitative characterizations of lesion appearance)</li>
-                            </ul>

-                        <p>
-                            Currently IDC will consider submissions from NCI-funded driving projects and data from special

-                            IDC only hosts public datasets. It does not support access limitations,
