Outcome Framework

Services We Provided

01
Project Lead

Managed client communication, project coordination, requirements, and feedback to keep the annotation workflow organized and on track.

02
Medical Image Annotators

Two annotators worked on detailed CT imaging data, focusing on accurate and consistent 3D medical image annotation within MD.ai.

03
QA Specialist

Reviewed completed annotations before delivery, checking consistency, accuracy, and alignment with the project's requirements.

04
Clinical Verification

Completed annotations were reviewed by an expert radiologist through MD.ai, adding an important layer of clinical validation to the workflow.

A Structured Workflow Built for Medical AI

A clearly defined team structure kept the medical image annotation workflow efficient and consistent. The Project Lead managed client communication and requirements, allowing the annotation team to focus on accurate 3D medical image annotation. A dedicated QA checkpoint reviewed completed work before delivery, helping identify inconsistencies early and maintain reliable annotation standards across complex medical imaging data.

From Precision to Impact

The completed medical image annotations directly supported an FDA submission, demonstrating the accuracy and clinical reliability of the annotation workflow for a high-stakes medical AI application. All completed annotations were verified by an expert radiologist through MD.ai's built-in QA workflow. Positive client feedback on annotation quality further confirmed that the delivered medical imaging data met the project's clinical and regulatory requirements.Completed annotations were verified by an expert radiologist through MD.ai's built-in QA workflow. Body Check LLC additionally provided positive acknowledgement of annotation quality via email, confirming alignment with clinical and regulatory standards.

Challenges & How We Solved Them

Adapting to a Specialized Medical AI Platform

Working with MD.ai’s 3D segmentation tools required hands-on training and platform familiarization. We developed project-specific SOPs and used client walkthroughs and reference materials to help the team quickly establish a consistent medical image annotation workflow.

Annotating Complex Anatomical Structures

Structures such as cardiac calcifications, liver boundaries, and vertebral-level body composition required a high level of precision. Clear annotation guidelines, practical training, and continuous client feedback helped the team handle complex and ambiguous cases consistently.

Managing Variations in CT Imaging

Differences in CT scan contrast, resolution, and slice thickness created challenges for consistent segmentation. Standardized SOPs and regular quality reviews helped the team adapt the 3D medical image annotation process to different imaging conditions.

Operational & Workflow Efficiency

Delivering high-quality annotations across multiple time-sensitive projects required strict coordination. Structured training and regular client check-ins kept quality high without sacrificing delivery timelines.

Quality Assurance Process

Quality was embedded at every stage of the workflow not treated as an afterthought. The QA Specialist reviewed all annotator output within MD.ai before delivery, ensuring consistency and accuracy. An expert radiologist at Body Check LLC conducted final verification, providing an additional layer of clinical oversight. Client feedback loops were maintained throughout the project to catch and resolve ambiguities early.

CONCLUSION

High-stakes medical AI requires more than accurate annotations—it requires a reliable process built around precision, consistency, and quality. Through specialized medical image annotation, 3D segmentation, structured QA, and expert radiologist verification, our team delivered clinically reliable imaging data that supported a critical FDA submission. This project demonstrates how the right combination of technology, trained expertise, and quality-focused workflows can help healthcare AI teams turn complex medical imaging into dependable data for real-world applications.
