About the research
The goal of this clinical trial is to compare, for the second reading of screening mammograms, the standard of care with an AI assisted scenario.
The main questions it aims to answer are:
- will the experimental pathway be non-inferior to the standard pathway?
- will the experimental pathway be economically superior to the standard pathway?
Participants will receive screening mammograms, as part of the breast cancer screening program. Researchers will compare the interpretation made by the second reader in the standard pathway with the AI assisted interpretation made by a different reader in the experimental pathway.
Read the full description
All mammograms eligible for a second reading, and included in the study, go through 2 arms:
- Conventional second reading by a radiologist accredited to do second reading in France (L2 control arm),
- Second reading assisted by the AI (L2-AI experimental arm): mammograms will be read by the AI first and only if deemed suspicious, a radiologist accredited to do second reading in France will review them.
The most pejorative assessment among the two arms is used as the final decision: if both arms consider the mammogram as negative, the participant won't be recalled, if one arm consider the mammogram as positive, the participant will be called back for further examinations.
Clinical performances and economical impacts of both scenarii will be compared.
Who may be able to participate?
The list below is the sponsor’s full registry wording. It can include conditions, prior treatment, test results and other requirements. A match in search does not mean you qualify.
Inclusion Criteria:
- Affiliated to the French social security system
- Whose mammograms meet the following characteristics: 4 (2 per breast, CC and MLO) meeting local regulatory standards and with correct DICOM metadata,
- Whose mammograms have been determined to be normal or to have benign lesions by the radiologist who performed the first reading of the images (L1) in the framework of the organized breast cancer screening program
- Having expressed her willingness to participate in the study, to undergo all the procedures and to make herself available for the expected duration of their participation,
- Having completed and signed the informed consent form.
Exclusion Criteria:
- Woman with breast implants,
- With clinical symptoms of breast cancer,
- With a history of breast surgery (breast reduction or surgery for benign lesion),
- Pregnant or breastfeeding,
- With medical conditions that may interfere with her ability to understand the requirements of the protocol or give informed consent,
- Deprived of liberty by judicial or administrative order,
- Participant whose mammogram images have at least one of the following defects: poor quality of the images, non-standard mammography (projection, magnification, compression), ML/LM/SIO/XCCL or XCCM view.
Treatment, groups and participation
The registry may describe treatments and study duration without a complete visit calendar. Ask the study team for the exact schedule, procedures, risks, costs and alternatives. Keep your usual care plan unless your treating clinician tells you otherwise.
- Assignment
- Not randomized
- Masking
- No masking
L2 - Standard second read
Interpretation of mammograms done by a radiologist accredited to do second reading in France.
L2-AI - AI-assisted second read
Interpretation of mammograms done by the AI-based device. Mammograms deemed suspicious by the AI (i.e., receiving an AI global score higher than a defined threshold) will be interpreted by a radiologist accredited to do second reading in France. Mammograms assessed as negative or low suspicious by the AI won't be further interpreted by a radiologist.

Secondary measures
Cancer detection rate
Time frame: End of the inclusion period 24 months
Number of biopsy proven cancers divided by the total number of patient receiving a second reading
Sensitivity and Specificity
Time frame: End of the follow_up period 48 months
True and false-positive rate
Economic impact
Time frame: End of the follow_up period 48 months
Difference in direct medical costs between the two arms Difference in annual budgetary impact on the French National Health Insurance between the two arms
Time-to-results
Time frame: End of the inclusion period 24 months
Time period \[in days\] between the day of the screening and the access to results
Reading time
Time frame: End of the inclusion period 24 months
