The point is not another number. It is a workflow-compatible risk signal that shows up when the patient is already in the system.

73 million missed opportunities

The signal is already in the CT. The system just does not collect it.

Every year, CT scans are performed for reasons unrelated to bone health. Meanwhile, a large share of patients who suffer fractures never receive a diagnosis beforehand.

These scans contain bone, muscle, and fat biomarkers that correlate with fragility risk, but that data goes unused.

The cost? Avoidable fractures, avoidable spend, and avoidable loss of independence.

Data exists

CT scans already contain the relevant biomarkers.

Data unused

Traditional workflows cannot extract it at scale.

Patients at risk

Warning signs go undetected until the fracture.

Built for operators, designed for outcomes

Different stakeholders care about different things. Here is what changes for each one.

Radiology groups

Workflow-first adoption

• Add preventive value without changing protocols
• PACS/API-ready outputs and structured reporting
• A path to new revenue streams and differentiated service

Health systems

Care gap closure

• Identify silent risk before the fracture event
• Automate stratification and care coordination triggers
• Align with value-based goals and population health

Investors and accelerators

Execution and defensibility

• Clear wedge: opportunistic CTs at massive scale
• Moat: calibration + multi-domain biomarkers + workflow
• Validation plan and regulatory pathway defined

Seeing the complete picture

Phantomless calibration plus multi-domain biomarkers enables opportunistic screening that actually scales.

We do not just measure bone density.

We measure fracture risk.

Phantomless calibration

Standardizes measurements across scanners without external calibration equipment.

Multi-domain analysis

Bone density, muscle quality, and fat distribution combined into a risk signal.

Universal compatibility

Designed for real-world CT variation, without workflow disruption.

How it works

Six steps. Zero workflow disruption.

Opportunistic Capture

Routine Scans, Hidden Insights

Opportunistic Capture

Every abdominal or chest CT already contains critical bone health data. BHI automatically identifies eligible scans from your existing imaging workflow—no additional radiation, no patient scheduling, no workflow disruption.

Universal Calibration

One Algorithm, Every Scanner

Universal Calibration

Our patented phantomless calibration technology standardizes measurements across any CT manufacturer—GE, Siemens, Philips, Canon—without external equipment. This breakthrough eliminates the biggest barrier to opportunistic screening at scale.

Intelligent Segmentation

AI That Sees What Matters

Intelligent Segmentation

Advanced neural networks automatically identify and isolate vertebral bodies, skeletal muscle, and visceral fat in seconds. Our models achieve >85% accuracy across diverse patient populations and scan protocols.

Multi-Domain Analysis

Beyond Bone Density

Multi-Domain Analysis

While traditional methods measure only bone, BHI extracts comprehensive biomarkers across three critical domains: trabecular bone density, muscle quality metrics, and fat distribution patterns. This multi-tissue approach captures the complete fracture risk picture.

Predictive Fusion

From Data to Risk Assessment

Predictive Fusion

Our proprietary AI model fuses multi-domain features through trained neural networks, generating a unified Bone Health Index that predicts fracture risk with 0.84 AUC—15–25% better than bone-only methods.

Seamless Integration

Insights Where You Need Them

Seamless Integration

BHI results flow directly into radiologist workflows via PACS integration or API, with structured reports, risk stratification, and automated care coordination triggers. From scan to action in under 60 seconds.

Clinical impact that scales

BHI creates value for patients and healthcare systems simultaneously—earlier detection, no workflow disruption, and measurable cost avoidance.

For patients

Early detection before fractures occur—catching decline when intervention is most effective
Longitudinal tracking monitors bone health changes over time using routine imaging
Zero additional burden—no extra appointments, no additional radiation exposure

For healthcare systems

113% more patients identified compared to traditional screening adherence rates
$40K–60K saved per prevented fracture through early intervention and treatment
Zero workflow disruption—seamless integration into existing radiology workflows

$2.5B

Annual cost avoidance potential

Estimated annual savings for Medicare with broad implementation and effective follow-through. Every prevented hip fracture saves $40,000–60,000 in acute care, rehabilitation, and long-term complications.

10:1 ROI on prevention vs. treatment costs

Built to deploy, built to scale

The wedge is simple: high-volume CT workflows, minimal friction, and a clear path from risk signal to action.

Commercial model (expected)

Per-site license + per-study usage

Start with a workflow pilot, then scale via a site license with usage-based processing. Integration via PACS or API.

Pricing is finalized with early partners to match volume, integration effort, and clinical outputs.

Go-to-market wedge

Outpatient radiology first

High CT volume, fast decision cycles, and direct incentives to differentiate services. Expand into health systems once the workflow is proven.

• Start: abdominal and chest CTs
• Deliverable: structured report + risk tier
• Outcome: referrals and preventive care coordination

Why we win

Signal + workflow + defensibility

Phantomless calibration makes the measurements comparable across scanners. Multi-domain biomarkers capture more than bone. The product lands where radiologists already work.

Why Quasar BHI is different

BHI is not a DXA replacement—it's an opportunistic, workflow-native risk signal designed to surface fracture risk earlier and at population scale.

Understanding the science

Three breakthroughs that enable opportunistic screening at scale

Quasar's proprietary calibration technology uses internal tissue references to standardize imaging measurements across scanner manufacturers and protocols. This breakthrough enables true opportunistic screening without external calibration equipment.

Vertebral focus

Automated vertebral identification and measurement.

Risk stratification

Structured output that supports triage and follow-up.

Multi-tissue view

Bone, muscle, and fat features in one index.

What makes this different

Phantomless

Only solution that eliminates external calibration equipment—enabling true opportunistic screening at scale

Multi-domain

First system to combine bone density, muscle quality, and fat distribution into unified fracture risk assessment

Universal

Works across all major CT manufacturers without protocol modifications or workflow changes
