Software that analyzes heart CT scans to detect coronary artery disease

Official title: CODEX1 TRIAL: Complete One-Stop-Shop Diagnosis Of Coronary Artery Disease On Computed Coronary Tomography Angiography: From the COMBINE-CT Study

Run by Instituto de Investigación Biomédica de Salamanca · NCT06977295 · Data updated 2026-11-12

This project will test a new software that uses past coronary CT scans to see if it can accurately find blockages and predict which patients might need procedures.

Is this trial a fit for you?

Likely a good fit

Adults (18+) who had a coronary CT angiogram between 2019 and 2024 and have a comparator diagnostic test (ICA, stress MRI, or alternate CCTA analysis) within one month are ideal candidates for inclusion.

Probably not a fit

Patients whose CT images are of insufficient quality or who lack nearby comparator diagnostic data would not be included and would not directly benefit from this analysis.

What this trial studies

CODEX-1 is a multicenter retrospective observational study using de-identified CCTA images from 1,000 patients collected at European centers between 2019 and 2024. The software combines automated stenosis detection and CAD-RADS categorization, CT-derived fractional flow reserve (CT-FFR), and quantitative plaque analysis, and runs entirely on-site. Outputs will be compared to invasive coronary angiography, stress MRI, or alternative CCTA analyses and to expert adjudication to measure diagnostic accuracy and inter-reader variability. All analyses are performed offline and no new tests or interventions are performed on patients.

Why it matters

Potential benefit: If successful, the software could provide faster, more consistent noninvasive diagnoses and help reduce unnecessary invasive angiograms.

How similar studies have gone: Prior studies of CT-FFR and automated plaque/stenosis tools have shown promise for improving diagnostic accuracy, but combining all three functions into a single on-site application is relatively novel and needs validation.
