Overview

Bunkerhill Abdominal Aortic Quantification (AAQ) is an FDA-cleared AI-powered algorithm designed to automatically measure the maximum abdominal aortic diameter on routine abdominal CT scans, including both contrast and non-contrast studies. This innovative tool turns everyday imaging into a crucial safety net for detecting silent abdominal aortic aneurysms (AAA), a life-threatening condition often missed until it’s too late.

Integrated into Bunkerhill’s Carebricks platform, AAQ streamlines care workflows by identifying at-risk patients and enabling seamless, guideline-based follow-up without requiring additional scanning, radiation, or disruption to existing radiologist workflows. The Carebricks platform leverages AI-powered reasoning and large language models (LLMs) to analyze structured and unstructured patient data, surface insights, and automate appropriate next steps, ensuring proactive and equitable care.

Developed at Stanford University and validated through Bunkerhill’s consortium of academic medical centers, AAQ represents a significant advancement in opportunistic screening, allowing for earlier identification and intervention for AAA, ultimately improving patient safety and outcomes.

What Physicians Need to Know

Cardiac CT/MRI Analysis
Bunkerhill AAQ automatically measures the maximum abdominal aortic diameter on routine abdominal CT scans, including both contrast and non-contrast studies. This enables opportunistic screening for abdominal aortic aneurysms (AAA) from everyday imaging.
AHA/ACC Guideline Alignment
The tool's measurements are integrated into automated follow-up workflows that include guideline checks and coordinate guideline-based surveillance or evaluation when interval growth of the aorta exceeds predefined thresholds.
Real-Time Alert Capability
Integrated within the Carebricks platform, AAQ can automatically identify patients requiring follow-up, flag concerning changes in aortic diameter over time, and initiate referral and authorization workflows for care teams. It also notifies the care team when growth thresholds are met.
Cardiovascular Risk Contribution
By accurately quantifying abdominal aortic diameter and identifying potential aneurysms, AAQ contributes to the overall cardiovascular risk assessment by surfacing at-risk patients for a significant cardiovascular condition. The broader Carebricks platform helps health systems identify and act on overlooked risks.
Physician Tip

Bunkerhill AAQ provides standardized, automated abdominal aortic diameter measurements from routine CT scans, facilitating opportunistic screening for AAA. Physicians can leverage this tool to efficiently identify at-risk patients, monitor aortic changes over time, and streamline guideline-based follow-up and referral processes, thereby enhancing patient safety and care coordination without additional imaging or workflow disruption.

Bunkerhill AAQ is seamlessly integrated into Bunkerhill's Carebricks platform. Carebricks is an AI-powered platform that analyzes structured and unstructured patient data, enabling automated follow-up workflows, guideline checks, longitudinal tracking, and coordinated messaging to providers or patients. It integrates with existing radiologist workflows and can leverage large language models and foundation models to enhance clinical reasoning and action.

Frequently Asked Questions

Bunkerhill AAQ integrates seamlessly into clinical workflows via the Carebricks platform, automatically measuring the maximum abdominal aortic diameter on routine CT scans. This automation streamlines the identification of abdominal aortic aneurysms (AAAs) and facilitates opportunistic population-wide screening, turning everyday imaging into a safety net for silent aneurysms.
Bunkerhill AAQ is an FDA-cleared AI-powered algorithm. Bunkerhill Health, the developer, adheres to stringent data privacy standards including HIPAA, SOC 2, and ISO 27001:2022, implementing controls such as data encryption and retention procedures to protect patient information.
Bunkerhill AAQ distinguishes itself by being the first and only AI-powered algorithm cleared to automatically measure abdominal aortic diameter on *both* contrast and non-contrast CT scans. This capability broadens access to automated measurements compared to existing cleared algorithms that typically analyze only contrast-enhanced studies, and it offers standardized, objective data over variable manual measurements.
While specific pricing for Bunkerhill AAQ is not publicly detailed, Bunkerhill Health has successfully secured national billing codes and reimbursement pathways from CMS for other AI algorithms, such as those for coronary artery and aortic valve calcium analysis. This indicates their commitment to establishing clear reimbursement frameworks for their AI solutions within the Hospital Outpatient Prospective Payment System (HOPPS).
A key limitation is that the results generated by the AAQ workflow are described as 'supportive, not definitive,' implying that physician oversight and interpretation remain crucial. While the AI automates measurements, clinical judgment is still necessary for verifying surveillance plans, scheduling follow-ups, and making definitive diagnostic or treatment decisions.
The AAQ algorithm was developed at Stanford University and validated through Bunkerhill's consortium of academic medical centers. This multi-institutional validation on hundreds of CT scans, including diverse datasets of both contrast and non-contrast studies, demonstrated consistently high performance across varied patient populations.
Bunkerhill AAQ significantly impacts radiologist workload by automating the previously manual and variable process of measuring abdominal aortic diameters, thereby improving efficiency. It standardizes measurements and integrates with automated follow-up workflows within the Carebricks platform, reducing the need for additional scanning or disruption to existing radiologist workflows.
