AI-Assisted Diagnostic Platform for Medical Imaging

Industry
Healthcare & Life Sciences

Client Overview

A fast-growing network of diagnostic labs aiming to reduce the turnaround time for analyzing medical images like X-rays and CT scans. Their radiologists were overwhelmed by the volume of images, leading to backlogs and potential delays in patient care. They needed a solution to help prioritize cases and assist in identifying potential abnormalities.

Client Testimonial

"CIS didn't just sell us an AI model; they became our technology partner. They took the time to understand our clinical workflow and the immense responsibility of working with patient data. The Azure Vision solution they built has reduced our average reporting time by 40% and acts as an invaluable 'second pair of eyes' for our radiologists. Their professionalism and commitment to HIPAA compliance were evident at every step." - Chief Medical Officer

Problem Image

Problem

The manual process of reviewing thousands of medical images was time-consuming and prone to human fatigue, creating a bottleneck that delayed patient diagnoses and treatment plans.

Key Challenges

  • 01

    Data Sensitivity : The solution had to be fully HIPAA compliant and handle Protected Health Information (PHI) with extreme care.

  • 02

    High Accuracy Requirement : The model needed to achieve near-human-level accuracy to be trusted by medical professionals.

  • 03

    Workflow Integration : The AI tool had to integrate seamlessly into the existing Picture Archiving and Communication System (PACS) used by radiologists.

  • 04

    Model Interpretability : Radiologists needed to understand why the model flagged a certain area, requiring model explainability features.

Our Solution

We developed a secure, HIPAA-compliant AI platform using Azure AI Vision and custom machine learning models to analyze medical images and highlight potential areas of interest for radiologists.

Secure Data Handling : We set up a HIPAA-compliant environment on Azure, using Azure Key Vault for encryption keys and strict Azure RBAC to control access to PHI. All data was de-identified before training.
Custom Computer Vision Model : We trained a custom object detection model using Azure Machine Learning on a labeled dataset of thousands of anonymized scans, achieving over 95% accuracy in identifying specific types of anomalies.
Responsible AI Dashboard : We implemented Azure's Responsible AI tools to provide model explainability (SHAP values), allowing radiologists to see which pixels contributed most to a prediction.
Seamless Integration : We built a lightweight web interface that integrated with the client's PACS system via API, overlaying the AI-generated insights directly onto the images in the radiologist's existing viewer.

Implementation & Execution

  • Icon

    Compliance-First Approach

    The project started with a joint review of all HIPAA security and privacy rules, with our certified ethical hackers involved in the architecture design.

  • Icon

    Data Annotation Pod

    We used our Data Annotation / Labelling Pod to assist the client's medical experts in preparing a high-quality, labeled dataset for training.

  • Icon

    Iterative Training

    Model training was an iterative process, with radiologists providing feedback on model performance after each cycle to refine its accuracy.

  • Icon

    User-Centric Design

    Our User-Interface / User-Experience Design Studio Pod worked directly with radiologists to design an intuitive and non-disruptive user interface.

  • Icon

    Phased Rollout

    The solution was rolled out to one lab initially, allowing for real-world feedback and adjustments before a network-wide deployment.

  • Icon

    Performance Monitoring

    We set up monitoring to track model accuracy and watch for "concept drift" (e.g., changes in imaging equipment affecting image quality) to trigger retraining.

Positive Outcome

1. Reduced Reporting Time

Average time to report on a scan was reduced by 40%, allowing radiologists to process more cases and reduce the backlog.

2. Improved Diagnostic Assistance

Radiologists reported higher confidence and efficiency, using the AI as a triage and confirmation tool.

3. Enhanced Prioritization

The system automatically flagged complex or high-priority cases, ensuring they were reviewed first.

4. Full Compliance

The platform successfully passed an independent HIPAA compliance audit.
