This document is intended to provide details of The Cancer Imaging Archive's (TCIA) protocol for data collection, de-identification and curation so that submitting sites are comfortable with the protocol prior to agreeing to use the established procedures to accomplish these activities. The purpose of this protocol is to assure the research community that this process is implemented under the supervision of the University of Arkansas for Medical Sciences (UAMS) Institutional Review Board (IRB # 205568).
The Department of Biomedical Informatics at UAMS hosts The Cancer Imaging Archive for the National Cancer Institute (NCI). At NCI’s direction, TCIA personnel collect and curate clinical and pre-clinical (animal studies) Radiology and Pathology images, clinical trial data (including patient demographics and clinical outcomes), annotations and image derived features and other types of clinical research data (e.g., gene expression profiles) as directed by NCI and the research community. Data comes from NIH programs, funded research and clinical trials. In most instances this data is the result of completed clinical trials, but with NCI permission TCIA may also serve as the information repository for prospective clinical trials, pre-clinical research studies and co-clinical trials.
The ultimate goal of this data collection is to make the information publicly available. The TCIA team at UAMS ensures all data is fully de-identified in accordance with international standards, US laws and UAMS IRB protocol requirements. TCIA then makes the data freely and openly available under the Creative Commons licensing as shown below:
“This collection is freely available to browse, download, and use for commercial, scientific and educational purposes as outlined in the Creative Commons Attribution 3.0 Unported License. See TCIA's Data Usage Policies and Restrictions for additional details. Questions may be directed to help@cancerimagingarchive.net.”
Prior to uploading data to TCIA, the submitter must obtain IRB approval (or ethics board equivalent) from their institution allowing them to submit a de-identified version of their data to TCIA. The NCI and the submitting site IRB are jointly responsible for reviewing the consent under which data to be submitted to TCIA was originally collected.
Submission sites are provided with de-identification tools by the UAMS TCIA team. These tools have been approved by NIH and comply with the Digital Imaging and Communications in Medicine (DICOM) international standard for medical image de-identification. Following industry best practices, TCIA uses a standards-based approach to de-identification of DICOM images and non-image data to insure that all data make publicly available are free of protected health information (PHI). The TCIA de-identification process ensures that the HIPAA de-identification standard is met by following the Safe Harbor Method as defined in section 164.514(b)(2) of the HIPPA Privacy Rule.
All data is encrypted prior to transmission to UAMS. All incoming data is captured in a quarantine system and treated as if it contains PHI. All TCIA personnel are trained in HIPAA regulations and procedures. TCIA servers are managed by UAMS IT as if they were UAMS clinical systems. Once the full analysis and de-identification is complete, data is moved to a separate public repository and made available to the research community. This process has been reviewed by the UAMS Chief Security Officer.
Radiology Curation Overview
A TCIA submission expert will work with an Imaging point of contact from your site. The expert will provide all the required tools for de-identifying and sending your imaging data and will answer any questions you have throughout the process. Typically, site resources required will be time from a PACS or other technician who will set up the software on a standard computer, complete testing, and then download imaging studies from the local PACS to the installed software as they become available. Once setup and testing are completed, images are exported from the local accessible drive to the Clinical Trial Processor (CTP) Wizard, which is an application provided by TCIA and used to de-identify and transmit images to TCIA. De-identification of the data is highly automated, and the de-identified data is transferred to TCIA via HTTPs by the CTP Wizard.
This process includes:
1. Install pre-configured Clinical Trials Processor (CTP or CTP-Wizard) java software and use it to submit your data.
- CTP runs on windows/mac/Linux and does not require any specialized hardware but does require JAVA software be installed
- CTP will perform an initial de-identification of the data according to DICOM standards (Attribute Confidentiality Profile – DICOM PS 3.15: Appendix E) before it leaves your institution.
2. TCIA quality control and curation staff will work with you to ensure the data are fully de- identified and received. Additional reviews are performed, and any remaining PHI are deleted if found.
3. TCIA will publish the final data set with a descriptive page and announce its addition via our mailing list and social media channels.
Submission Site role:
With help from a TCIA submissions manager, Researchers submit imaging data using the Clinical Trial Processor (CTP) Wizard. There are four basic steps to submitting your data to TCIA using the CTP Wizard:
1. Locate the data you will be sending to TCIA and export it to the computer where you’d like to install our submission software.
Note: Please do not utilize your PACS system or other de-identification software as this usually deletes critical information researchers will need to make use of the data.
2. Download and unzip CTP Wizard
3. Complete the mapping table file to assign anonymous patient IDs and to offset study dates
4. Launch CTP Wizard to process and transfer the DICOM files to TCIA
De-identification Overview
Following industry best-practices, TCIA uses a standards-based approach to de-identification of DICOM images to insure that images are free of protected health information (PHI). The TCIA de-identification process ensures that the HIPAA de-identification standard is met by following the Safe Harbor Method as defined in section 164.514(b)(2) of the HIPPA Privacy Rule. The standard for de-identification of DICOM objects is defined by Attribute Confidentiality Profile – DICOM PS 3.15: Appendix E. At the submitting site, a DICOM PS 3.15 compliant script removes or modifies DICOM tags deemed to be unsafe (See table 1 for a complete listing). TCIA incorporates the “Basic Application Confidentiality Profile” which is amended by inclusion of the following profile options: Clean Pixel Data Option, Clean Descriptors Option, Retain Longitudinal With Modified Dates Option, Retain Patient Characteristics Option, Retain Device Identity Option, and Retain Safe Private Option. The de-identification rules applied to each object are recorded by TCIA in the DICOM sequence Method Code Sequence [0012,0063] by entering the Code Value, Coding Scheme Designator, and Code Meaning for each profile and option that were applied to the DICOM object during de-identification. The DICOM standard for de-identification of objects defines a minimum set of elements to de-identify to be in compliance with the standard. It is up to the user doing the de-identification to insure that PHI is removed or cleaned according to the laws and practices in place at the time de-identification occurs.
Details
Base level de-identification
The Basic Application Confidentiality Profile requires that Patient Name and Patient ID are either blanked or modified. TCIA incorporates an ID mapping between the original Patient ID and the ID that the images will have within TCIA. The mapping table is created at the image submitting site, the mapping performed prior to the images leaving the sites host computer, and TCIA never sees the original Patient ID. The remapped Patient ID is also mapped to the Patient Name field. This is done for the case where a DICOM viewer or application being used by the TCIA user that downloaded the data would require a Patient Name to be present. To show that the Patient Identity has been removed, the term “YES” is written into DICOM tag 00120062 “PatientIdentityRemoved”.
In general, the Basic Application Profile specifies removal or modification of any tag that by definition would contain PHI that could be used either alone or together with other information to uniquely identify a subject. Removal of detailed geographic information, dates, exam identifiers, patient demographics, free text entry fields, vendor private tags, etc. are all done to minimize the possibility of being able to uniquely identify an individual. The options to the DICOM de-identification standard allows for retention of information to help make the data scientifically valuable, but as more options are added the chance of PHI is increased and a rigorous de-identification process must be followed.
Exam Identifiers - DICOM makes extensive use of universal identifiers (UID) that could be used to identify a subject if a user had access to the PACS system at the institution where the images originated. The Basic Application Confidentiality Profile requires that all UIDs be removed or modified. TCIA uses its own root UID, appends an 8 digit string in the form of xxxx.yyyy (where xxxx is related to the collection and yyyy is related to a submitting site) and then appends a hashed value of the original UID. UIDs have no special meaning other than serving as unique identifiers and the only reason TCIA adds the 8 digit string is to minimize the possibility of two images being assigned the same UID as images come from many different sites. This technique insures that images stay associated with the appropriate series, study, and subject as well as ensuring that referenced images between secondary capture images, structured reports, PET/CT, etc. are still valid references to images within TCIA. Any image resubmitted to TCIA will have the same UID to avoid the same image appearing twice with a different identifier. Original accession numbers are hashed with a 16 bit string to prevent linking of DICOM objects back to the submitting site.
Dates - The Retain Longitudinal With Modified Dates Option allows dates to be retained as long as they are modified from the original date. Date and Date-Time fields in TCIA DICOM image headers have been offset based on a random number, but the longitudinal relationship between dates is maintained. Therefore, a researcher won’t know the precise date the scan occurred, but if a follow up scan was performed 120 days later, that same 120 day difference between scans of a subject will exist in the TCIA images. Dates that occur in DICOM tags other than Date or Date-Time fields are removed. An example of this would be a date entered into the Series Description field. If the date is associated with a library for Code Meaning then that date is preserved as the date would be required to look up the meaning in the correct version of the library. To show that the dates have been modified, the term “MODIFIED” is written into DICOM tag 00280303 “LongitudinalTemporalInformationModified”.
Optionally, a computed "Days from Baseline (e.g. diagnosis) can be inserted in the DICOM tag (0012,0050) Clinical Trial Time Point ID with the associated tag (0012,0051) Clinical Trial Time Point Description set to “Days from Baseline”. "Baseline Year" (e.g. year of diagnosis) can optionally be inserted in DICOM tag (0013,1051).
Patient Demographics – The keep Patient Characteristics Option allows keeping some patient demographics for research purposes. The allowed fields are Patient’s Sex, Patient’s Age, Patient’s Size, Patient’s Weight, Ethnic Group, Smoking Status, and Pregnancy Status. If a subject is over 90 years of age, then the age must be listed as 90+. Allergies, Patient State (this is not where they live, rather their condition), Pre-Medication, and Special Needs are defined by the DICOM standard as “clean” and are kept by TCIA and examined for PHI along with all tags during curation. Other patient demographics such as birthdate, address, religious affiliations, etc. are removed or emptied.
The names of health care providers including staff, hospital name, assigned IDs etc. are removed from the DICOM objects in cases where there is enough detail to identify an individual or facility where the scan was done.
Free Text - The Clean Descriptors Option allows for DICOM tags where free text could be entered by a technician to be kept. The following tags fall under that option and are all kept, inspected, and cleaned of PHI by TCIA during the curation process: Allergies, Patient State, Study Description, Series Description, Admitting Diagnoses Description, Admitting Diagnoses Code Sequence, Derivation Description, Identifying Comments, Medical Alerts, Occupation, Additional Patient’s History, Patient Comments, Contrast Bolus Agent, Protocol Name, Acquisition Device Processing Description, Acquisition Comments, Acquisition Protocol Description, Contribution Description, Image Comments, Frame Comments, Reason for Study, Requested Procedure Description, Requested Contrast Agent, Study Comments, Discharge Diagnosis Description, Service Episode Description, Visit Comments, Scheduled Procedure Step Description, Performed Procedure Step Description, Comments on Performed Procedure Step, Requested Procedure Comments, Reason for Imaging Service Request, Imaging Service Request Comments, Interpretation Text, Interpretation Diagnosis Description, Impressions, and Results Comments. The TCIA de-identification script run at the submitting sites removes the field “Request Attributes Sequence” as that tag typically contains PHI and provides no scientific value. Many of these fields contain information valuable to research and are important to retain. For images that are submitted with missing Series Descriptions, TCIA will add text to Series Descriptions to help researchers during TCIA image searches. When a missing series description is encountered, TCIA staff will use the following approach: Enter “LOCALIZER” if the ImageType contains the word localizer; Enter “Contrast” and then append the value contained in Contrast Bolus Agent if a value is present; if Contrast Bolus Agent is missing or empty other tags will be examined to see if a series was scanned with contrast (The Image Comments field is often used by sites to denote contrast); if the Image is an MR then TCIA will map the Scanning Sequence parameters into the Series Description; if none of those conditions apply then TCIA will map Scan Options or simply enter “none” into the Series Description field.
Devices - The Retain Device Identity Option of the DICOM de-identification standard allows for the retention of information related to the scanner used. The option allows for the following relevant tags to be retained: Station Name, Device Serial Number, Device UID, Plate ID, Generator ID, Cassette ID, Gantry ID, Detector ID, Scheduled Study Location, Scheduled Study Location AE Title, Scheduled Station AE Title, Scheduled Station Name, Scheduled Procedure Step Location, Performed Station AE Title, Performed Station Name, Performed Station Name Code Sequence, Scheduled Station Name Code Sequence, Scheduled Station Geographic Location Code Sequence, and Performed Station Geographic Location Code Sequence. TCIA removes Station Name as part of its de-identification process as Station Name often contains information related to the site where the scan occurred. The other tags listed above are retained if they are found to be free of PHI after TCIA curation of the submitted DICOM objects.
Private Tags - Unfortunately, there are many cases where vendors do not make the conformance statement for a piece of equipment publicly available or do not adequately define what is stored in the private tags, but these fields are extensively used by DICOM vendors to store information about the scans which are sometimes necessary for researchers to utilize the data. When a submitting site sends DICOM data to TCIA all private tags are retained and then de-identified by TCIA during curation of the data according to the Retain Safe Private Option. The Retain Safe Private Option allows for the retention of DICOM tags stored in the private fields. TCIA uses a private tag dictionary maintained by the Posda curation toolkit to decide the disposition of a vendor written private tag. The Posda private tag dictionary is a compilation of 4 well-known private tag dictionaries, the TCIA De-identification Knowledge Base (DeID KB), Grassroots DICOM, DICOM3tools, and DCMTK. The addition of the other 3 private tag dictionaries allows for an expanded set of scientifically useful tags to be retained. To implement the new Posda private tag dictionary, TCIA resolved any discrepancies between the 4 included dictionaries and assigned dispositions to all private tags ever seen by Posda. Unique values seen within the private tags were inspected to ensure that dispositions were correctly assigned. If a new private tag is encountered in the Posda database that does not have a private tag disposition, values are inspected in relation to the tag description together with values in the tags and a disposition is assigned. If there is no existing private tag description, an attempt is made to find a manufacturer’s definition of the tag. If no such description can be found the disposition is defined to remove the tag. TCIA will remove any private tags from the images that are not specified in the private tag dictionary or are defined as containing a form of PHI such as name, SSN, etc. All date and datetime private tags that are retained are offset using the same offset as applied to the standard tags for the image. All private tags containing UIDs are assigned a TCIA root and appended with a hashed value as done with the standard tags. This ensures all references to other images contained within TCIA are maintained. A manual inspection of all private tags is performed using tagSniffer reports and any PHI that may be found is removed, emptied, date offset, or hashed as appropriate.
Private Tag Disposition Table
Body Part Examined - When images are made public, a single body part examined, corresponding to the cancer of interest, is assigned to all images. If the collection consists of sarcoma images (or any other cancer affecting multiple organs within the image collection), there may be multiple body parts assigned, though only one to any series. In phantom collections, body part examined is simply labeled “PHANTOM”.
All Tags - The TCIA de-identification process ensures that every DICOM tag of every DICOM object is free of the 18 forms of PHI as currently defined by the Safe Harbor Method. At the submitting site, a DICOM PS 3.15 compliant script removes or modifies DICOM tags deemed to be unsafe (See table 1 for a complete listing). At TCIA, a software routine known as tagSniffer extracts every unique value found within a collection being curated and prints them to a report. This report is examined by curators and any actions necessary to remove PHI is applied when moving the images from the Intake server to the Public Server. Every DICOM image is inspected by curators for burned in PHI. Once the images reach the Public Server, the tags are inspected by two curators for PHI using new tagSniffer reports. Images are spot checked for any burned in PHI.
The following table details the de-identification performed at the submitting site by way of a TCIA supplied de-identification script.
