DeepMedFake-Assisted Detection of Synthetic and Discordant Medical Images

12. september 2026 opdateret af: Lv, Han, Beijing Friendship Hospital

Evaluation of the Clinical Performance and Multi-Setting Application of an AI-Based Medical Image Verification System

This prospective randomized controlled trial will evaluate whether DeepMedFake improves the identification of medical images that require further verification. DeepMedFake is an artificial intelligence-based medical image analysis system that provides an image-authenticity risk assessment, a patient-image consistency risk assessment and a recommendation regarding further verification. Hospital physicians and healthcare audit professionals will participate in a randomized two-period crossover design. Each participant will assess one case set with DeepMedFake assistance and the other without AI assistance. The primary outcome in each cohort is the sensitivity of the final verification decision, evaluated separately in the hospital clinical and healthcare audit cohorts.

  • Provided written informed consent before participation.

    （1）Hospital clinical cohort participants must also meet the following criteria:

  • Hold a valid physician qualification.
  • Currently practice in ophthalmology, radiology, ultrasound medicine, or a clinical specialty in which imaging of the neurological or cerebrovascular, cardiovascular, thoracic, abdominal, or musculoskeletal domain is routinely reviewed.
  • Have direct professional experience reviewing all imaging modalities and clinical imaging domains assigned to them in the study.

  • Routinely use the assigned medical images for image interpretation, image verification or clinical decision-making.

    （2）Healthcare audit cohort participants must also meet the following criteria:

  • Currently work in healthcare audit, medical reimbursement review, medical-cost review or medical-material verification.
  • Have experience reviewing medical imaging materials as part of their routine work.
  • Have knowledge required to interpret the medical images and patient information presented in the study and to determine whether further verification is required.

Exclusion Criteria:

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: Crossover Sequence A
Participants undergo unassisted review of case set S1 during Period 1, followed by DeepMedFake-assisted review of case set S2 during Period 2.
Enhed: DeepMedFake
DeepMedFake is an artificial intelligence-based medical image analysis system designed to support the detection of synthetic medical images and authentic medical images paired with discordant patient information. It provides an image-authenticity risk assessment, a patient-image consistency risk assessment and a recommendation regarding further verification. In this study, DeepMedFake is used as a decision-support tool to assist participants in determining whether the image requires further verification before downstream clinical or healthcare audit use. Final judgments and verification decisions are made by the participants.
Eksperimentel: Crossover Sequence B
Participants undergo DeepMedFake-assisted review of case set S1 during Period 1, followed by unassisted review of case set S2 during Period 2.
