CT VScore+

Slice_00035_H710

Automated coronary calcium scoring—designed to reduce manual post-processing and support efficient, standardized cardiac CT workflow. Cardiac CT workflow with evaluation-based results demonstrating significant reductions in processing time.1

Embracing the Challenge

Coronary calcium scoring is a high-volume cardiac CT workflow performed in hundreds of thousands of CT scans annually.

Despite its routine nature, calcium scoring often relies on manual interaction and repetitive steps that require time and focused attention from technologists and physicians.

 

In today’s growing cardiac CT environment, staffing constraints combined with increasing imaging volumes, can strain internal post-processing capacity. In response, some health systems seek external processing support to manage volume demand, which can introduce additional handoffs and increase workflow complexity. Enabling automation within the existing clinical environment allows clinical care teams to manage volume in-house while preserving clinician oversight and supporting efficient, consistent, and scalable cardiac CT operations.

 

In structured evaluation at South Tampa Cardiology, automated calcium scoring demonstrated a 57% reduction in processing time compared to manual workflows, highlighting the impact automation can have in high-volume cardiac CT environments.

Clinical Advantages

Designed to Support Workflow Efficiency

Automated generation of coronary calcium scores can help reduce manual post-processing steps and support efficient cardiac CT review with evaluation-based findings demonstrating meaningful time savings compared to manual workflows.1

 

Supports Consistent Scoring and Reporting

Standardized scoring methods and reference database context help support consistent documentation across users and studies.

 

Preserves Clinician Oversight

Users can review, edit, or clear automated results, ensuring clinicians remain the final decision makers with most automated results requiring minimal or no adjustment in clinical evaluation.1

 

Seamless Reporting Integration

Standardized result extraction supports integration into downstream reporting and clinical systems.

Validated Performance (Evaluation-Based)1

Findings from structured evaluation of 100 cardiac CT cases at South Tampa Cardiology:

  • 57% reduction in processing time compared to manual workflows
  • 2.3× faster calcium scoring on average
  • 79% of cases required no user edits
  • 21% required minor adjustments
  • High agreement with clinical expectations
  • In select cases, previously undetected calcium was identified, impacting risk classification

Results derived from structured evaluation. Individual results may vary.
