Why
Parkinsonian syndromes affect millions of people worldwide. Dopamine transporter (DaT) imaging helps clinicians distinguish neurodegenerative parkinsonian syndromes from other conditions, and reading these scans reliably takes specialized expertise in nuclear medicine.
About one in five DaT scans is difficult to interpret, especially in early-stage or atypical cases. This can delay diagnosis, complicate treatment decisions, and add to the workload of specialist readers. AI tools that read DaT scans accurately and consistently could help expand access to expert-level diagnostic support and accelerate research into neurodegenerative disorders.
The Solution
The goal of the DaT Parkinson's Challenge was to develop computer vision models that classify DaT scans as normal or abnormal. The challenge used a multicenter dataset of DaT scans collected and annotated by French experts across ten hospital centers. Scan resolution and acquisition settings varied from center to center, so models had to generalize across institutions and scanners.
Participants submitted their trained models and inference code, which ran on held-out test scans to predict the probability that each scan was abnormal. Submissions were ranked by log loss.
The Results
More than 1,000 participants joined the challenge, and 373 individuals and teams generated over 2,000 submissions. The winning solutions achieved log loss scores of 0.25-0.27 on the private test set. In terms of area under the ROC curve, all three winning models scored around 0.95.
All three winning solutions focused on the striatum, the region where dopamine transporter uptake concentrates and where abnormal scans show reduced and/or asymmetric uptake. Approaches ranged from Siamese neural networks that compare the left and right sides of the striatum to 2D maps of clinical features, and more.
The results suggest that computer vision models can classify DaT scans reasonably accurately across the range of scanners and acquisition settings in the dataset. Tools like these could give specialist readers consistent support, including on scans that are difficult to interpret.
See the results announcement for more information on the winning submissions and the participants who developed them. The winning models will also be indexed in the Bibliothèque Ouverte d'Algorithmes en Santé (BOAS), France's open health algorithm library.

DaT Parkinson's Challenge: Rules and Terms of Data Use
DrivenData Competition Rules
GUIDELINES
These guidelines are intended to summarize a few main features of the competition rules. Full details are provided in the competition rules below.
One account per participant
You cannot sign up to DrivenData from multiple accounts and therefore you cannot submit from multiple accounts.
Private sharing of code
Privately sharing code or data outside of teams is not permitted.
Submission limits
The number of submissions allowed is restricted to a fixed value or rate on a per-competition basis. Any attempt to circumvent this limit will result in disqualification.
Documentation for winning solutions
Winning solutions must be documented using the version of the Winning Model Documentation Template that will be provided to top-ranking participants to be eligible for recognition and prize money if offered.
Winner License Type: Open source license
Winning solutions need to be made available under The MIT License (an open source software license commonly described at http://opensource.org/licenses/MIT) in order to be eligible for recognition and prize money if offered. Unless otherwise specified on the challenge website, any software required to generate the solution must also be available under an open source license that does not prohibit free commercial use, so that solutions could be reproduced using only free open source software.
External Data Rule: External data with rights
External data is permitted in this Competition provided Participants have all rights, licenses and permissions to use the external data as contemplated in the Competition Rules, and that such data complies with any external data restrictions stated on the Competition Website. Any use of external data must be pursuant to and in accordance with a valid license that permits use of the external data in this Competition without the need for additional approvals from any third party.
Use of test data
Unless otherwise specified on the website, each test data sample should be processed independently during inference without the use of information from other cases in the test set. By default, this precludes using information gathered across multiple test samples as feature inputs or target labels for model training, for instance through pseudo labeling or unsupervised learning on the test set. As a result, running model training code with the same training data but a different set of test data or no test data should produce the same model weights and fitted feature parameters. Eligible solutions must be able to run inference on new test data automatically, without retraining the model.
Questions?
The challenge rules are in place to promote fair competition and useful solutions. If you are ever unsure whether your solution meets the competition rules, ask the challenge organizers in the competition forum or send an email to info@drivendata.org.

Selection of winners
This Competition is a challenge of skill and the final results are determined by evaluating a combination of quantitative and qualitative factors, as more fully described on the Competition Website. For that portion of the Competition evaluated quantitatively, the results will be determined solely by leaderboard ranking on the private leaderboard based on an objective statistical evaluation metric published on the Competition Website prior to commencement of the Competition (subject to compliance with these Competition Rules). Participants' scores and ranks on the Competition Website at any given stage of the Competition will be based on the objective statistical evaluation metric described on the Competition Website, as determined by applying the predictions in the Submission to the ground truth of a validation dataset whose instances were a fixed set sampled from the Data. Scores displayed on the public leaderboard while the competition is running may or may not be the same as the final scores on the private leaderboard, depending on how samples from the Data are used for evaluation. For that portion of the Competition evaluated qualitatively, the results will be determined by a panel of judges, as more fully described on the Competition Website. As more fully described on the Competition Website, the Competition may have quantitative winners, qualitative winners, combined quantitative and qualitative winners, or all three.
The evaluation metric or judging rubric used for scoring and ranking Submissions will be displayed on the Competition Website.
The anticipated number of and amount of prize awards that will be awarded for this Competition are set forth on the Competition Website; however, DrivenData is not obligated to make all or any awards and reserves the right, in its sole discretion, to award fewer than the anticipated number of awards if an insufficient number of entries are deemed worthy in accordance with the evaluation criteria and challenge requirements.
Any prize awards are subject to verification of eligibility and compliance with these Competition Rules. All decisions of DrivenData, the Competition Sponsor and/or judges will be final and binding on all matters relating to this Competition. DrivenData reserves the right to examine the Submission and any associated code or documentation for compliance with these Competition Rules. In the event that the Submission demonstrates a breach of these Competition Rules, Competition Sponsor or DrivenData may at its discretion take either of the following actions:
- disqualify your Submission(s); or
- require that you remediate within one week any issues identified in your Submission(s) (including, without limitation, the resolution of license conflicts and confirmation of the fulfillment of all obligations required by software licenses). DrivenData is under no obligation to alert you of any issues with your Submission or permit you to remediate any identified issues.
A tie between two or more valid and identically ranked submissions will be resolved in favor of the tied submission that was submitted first.
A Participant may decline to be nominated as a Winner by notifying DrivenData directly within one week following the Competition deadline, in which case the declining Participant forgoes any prize or other features associated with winning the Competition. DrivenData reserves the right to disqualify a Participant who so declines at DrivenData's sole discretion if DrivenData deems disqualification appropriate.
Prizes and conditions
If the Competition has a prize, the Prize Winner(s) will be notified by email. The Prize Winner(s) will receive their prizes awarded as a check or electronic transfer from DrivenData.
If a Team wins a prize, all Team members must submit a single written statement describing how the prize is to be allocated among the Team members. If the Team fails to submit such statement within 10 days after DrivenData requests it, then DrivenData will distribute the prize among Team members in equal shares and will have no further obligation to winning Team members.
As a condition of receipt of a prize, winner must deliver their solution’s code and documentation to DrivenData. The source code must contain a description of resources required to build and run the solution, and should be able to sufficiently reproduce winning results and generate predictions on new data samples with and without retraining. The accompanying documentation should be consistent with DrivenData’s Winning Model Documentation Template, a version of which will be provided to winners after the competition. Winner must complete the specific version of the documentation template provided for the competition. Winner must also sign and return any documents provided in connection with prize acceptance as may be required by DrivenData or Competition Sponsor, including without limitation eligibility certifications and U.S. tax forms.
The prize may be awarded to an alternate winner if required documentation is not returned within fifteen (15) days after mailing to winner, if prize notification letter/email or prize is returned as undeliverable, if winner does not respond to an email or other communication from DrivenData within seven (7) days of the date sent, or if the winner, in DrivenData’s judgment, does not respond to reasonable requests for information related to prize delivery or is otherwise unable or unwilling to coordinate prize delivery within fifteen (15) days after prize notification. Allow thirty (30) days for prize delivery. By accepting any prize/award, Winner agrees to allow DrivenData and/or the Competition Sponsor to disclose Winner’s first name, first initial of last name, and city of residence, as well as prize information to the extent required by law, and if so required by law, Winner agrees to the disclosure of additional personal information, all without additional compensation.
