Radiologist - Medical Imaging AI Annotation (Remote)
Listing checked September 22, 2026 · pay as published by Mercor
Overview
Mercor seeks board-certified radiologists to build and grade clinical AI systems for medical imaging. The work sits away from patient care. You label findings, write reference reports, review model output, and define grading standards so imaging AI can be measured against expert judgment. Streams differ in task length, from short structured labeling to full case authoring, and assignments depend on subspecialty, availability, and interest.
What You'll Do6
- 1Interpret imaging cases with patient context and record each step of diagnostic reasoning, not just the final impression.
- 2Label discrete findings against a defined schema: presence, location, laterality, severity, and interval change.
- 3Author reference reports that show the read a study should produce, creating ground truth for model evaluation.
- 4Review AI-generated reads against clinical standards and flag hallucinated findings, missed findings, and unsupported certainty.
- 5Draft grading criteria and guidelines that separate an excellent read from an acceptable one so reviewers apply consistent judgment.
- 6Write difficult imaging questions that test the limits of current model reasoning.
Requirements12
- 1MD or DO with a completed diagnostic radiology residency and ABR board certification or equivalent, or board-eligible status with residency finished.
- 2Active unrestricted medical license in your country of practice.
- 3Two or more years of post-residency reads with full responsibility for final reports.
- 4Current or recent practice with high-volume reads.
- 5Precise use of structured reporting standards such as BI-RADS, LI-RADS, Lung-RADS, TI-RADS, or others tied to your subspecialty.
- 6English fluency in writing and speech.
- 7Minimum 15 hours each week, with capacity to concentrate those hours when a stream has a deadline.
- 8Fellowship training in neuroradiology, musculoskeletal, body/abdominal, chest, breast, or pediatric imaging.
- 9U.S. licensure and board certification.
- 10Medical image annotation, AI evaluation, or dataset curation experience.
- 11Teaching, rubric design, or resident assessment background.
- 12Published research or sustained technical writing, with a sample link.
Who Should Apply
Candidates who hold a diagnostic radiology residency, active board certification, and at least two years of post-residency reads will match this work best. Fellowship training in a subspecialty such as neuroradiology, breast, or chest imaging helps, and prior annotation or AI evaluation experience gives you an edge. The role suits radiologists who can commit 15 or more hours each week and write clear reasoning for every finding. The work suits less those without a completed radiology residency, an unrestricted license, or interest in non-clinical tasks. Common reasons applicants score low include vague diagnostic reasoning that skips steps, and reports that miss structured standards like BI-RADS or Lung-RADS when those schemas apply.
Salary Insight
Mercor lists $200 to $400 per hour for this contract engagement. That range sits at the top end for expert medical annotation and AI evaluation work, and it matches radiologists with board certification, active licensure, and several years of independent reads. Pay is tied to the stream you join and the throughput target you receive.

Application Tip
In your application, name the structured reporting systems you use most, such as LI-RADS or BI-RADS, and describe one recent high-volume read period with case counts. Link a writing sample if you have published research or teaching materials, since Mercor asks for that on preferred qualifications.

SME Careers
VerifiedRadiologist SME for AI Imaging Review and Content
This remote, hourly contract places you as a Radiology SME to review AI-generated imaging responses and to craft expert content across modalities such as CT, MRI, and ultrasound within a secure PACS workflow. You will assess accuracy, safety, and reasoning in step-by-step clinical problem solving, delivering precise written feedback on imaging appropriateness, differential diagnosis, and protocol choices. The role emphasizes prudent judgments around contrast use, radiation dose, and pregnancy considerations, with meticulous attention to missed findings and clear explanations. You will collaborate remotely, contributing to AI model evaluation, training data improvements, and peer review workflows to help shape leading radiology content and AI solutions.
Mercor
VerifiedDermatologist - Clinical AI Image Evaluation (Remote)
Board-certified dermatologists join Mercor to build and review clinical AI systems without seeing patients or issuing live diagnoses. The work centers on dermatological image interpretation, structured annotation, and AI output evaluation. You enter a shared expert pool after onboarding, then move among workstreams based on subspecialty, availability, and interest. Cases can take about 10 minutes for schema-based labeling or up to an hour for full case authoring, and each stream carries its own throughput target.
Mercor
VerifiedPhysician (MD/DO) - Remote Clinical AI Evaluation
Mercor needs residency-trained physicians for non-clinical projects that shape how clinical AI systems get measured. You will use your clinical background to build grading criteria, review clinical dialogues, and perform reasoning annotation. The role involves no patient care and no live diagnosis. Mercor runs a shared expert pool, so after onboarding you may join several workstreams at once based on your specialty and availability. Assignments shift as priorities change, and you can move between streams.
AfterQuery
VerifiedRadiologic Technologist Expert - Remote Contract
AfterQuery needs ARRT-certified radiologic technologists to help frontier AI labs sharpen how their models reason about medical imaging. You write realistic imaging scenarios that hinge on patient positioning, technique selection and radiation safety, then supply reference answers that explain why one protocol choice beats another. The work sits inside the Medicine department and runs as contract engagement at roughly 10 hours each week. Everything happens remote and async, so you decide when those hours land. Your grading also catches model output that sounds plausible but would lead to a repeat exposure or an unsafe study.
Mercor
VerifiedMedical Expert (M.D./D.O.) - Remote Part-Time
Mercor keeps this listing open for physicians who want to shape how frontier AI models handle clinical reasoning. The work fits around your practice: you might write a clinical vignette from a real case, complete with presentation, labs, and imaging, then supply the attending-level answer used as a reference. Other projects ask you to grade model output on diagnostic reasoning, checking whether a differential follows a sensible order, whether the model anchors on a first impression, and whether the proposed workup matches guidelines. You also flag recommendations that read well in a textbook but fail the patient in front of you because of comorbidities, contraindications, or access limits. Projects start on short notice, so Mercor draws from this pool when client demand matches your specialty.
Mercor
VerifiedMedical Expert - Remote AI Evaluation & Review
Mercor recruits health professionals who can supply the medical judgment that top AI research teams cannot generate on their own. The medicine pool is an open call, not a single opening, so it remains live while projects start on short notice. When a project launches, you may write a case from your practice with the presentation, workup, constraints, and reference answer that sets the standard for grading a model's attempt. You may also review model output for clinical reasoning, checking whether the differential follows a sensible order, whether a guideline applies to the patient, and whether the care plan is safe to carry out. Mercor sets rates per project, and most work is remote and part-time.
