U.S. Board-Certified Emergency Medicine Physician, 10+ Years of Experience — Stroke Data Annotation Project (SHS00305)

Project Summary

We are recruiting a U.S.-based, board-certified Emergency Medicine Physician with 10+ years of post-residency experience to participate in a multi-reader, multi-case (MRMC) study evaluating performance in ASPECTS scoring of acute ischemic stroke (AIS) on non-contrast CT (NCCT) imaging.

This study assesses diagnostic performance both with and without AI decision support developed by the sponsor. As a participating emergency physician, you will independently interpret stroke CT studies across two structured reading phases (aided and unaided) using a secure, web-based platform (RedBrick AI).

Project Details

Eligibility: U.S.-based, actively practicing, Board-certified Emergency Medicine Physician with 10+ years of post-residency experience.

Workload:

• 75 NCCT stroke studies
• Each case read twice:
  • Once unaided
  • Once AI-aided
• Total of 150 reads
• Cases released in batches of up to 10
  • Each batch exclusively aided or unaided
  • Batch order randomized and counterbalanced

Study Design:

• Phase 1: All 75 cases read once, randomly assigned to aided or unaided mode
• Phase 2: All 75 cases read again, switching modes relative to Phase 1

Estimated Time Commitment:

• ~8–10 minutes per case
• ~10–13 hours per phase
• ~20–26 hours total

Timeline:

• Target start: Early March
• Each phase completed within 4 weeks
• 4-week washout period between phases

Mode:

• Fully remote and asynchronous
• Work completed via the RedBrick AI annotation platform

Workflow:

• Initial training (1 week)
• Phase 1: Review all 75 studies (4 weeks)
• 4-week washout period
• Refresher training (1 week)
• Phase 2: Review all 75 studies again (4 weeks)

Task Description

Participants will review brain non-contrast CT (NCCT) images and:

• Identify affected hemisphere(s)
• Score all 10 ASPECTS regions
• Classify each region as:
  • Affected
  • Unaffected
  • Cannot be evaluated
• Exclude chronic infarcts according to ASPECTS guidelines

Responsibilities

• Complete assigned case sets within agreed timelines
• Maintain consistency and anatomical rigor across cases
• Follow protocol requirements precisely
• Perform all work independently

Requirements

• U.S.-based, Board-certified Emergency Medicine Physician
• 10+ years of post-residency experience
• Actively practicing with current clinical exposure to acute stroke care and/or stroke imaging interpretation
• Ability to work independently, asynchronously, and follow a protocol-driven study workflow.

If you are committed to advancing stroke evaluation in the emergency setting and want to help shape the future of AI-supported clinical decision-making, we invite you to apply and bring your expertise to this meaningful initiative.
