Goal
Detect when an AI-derived FFR value
becomes physiologically implausible
given other modalities.
The warning signal is coherence loss.
Not a single bad threshold.
Inputs
- ai_ffr_prediction
- myocardial_perfusion_index
- wall_motion_score
- stress_test_result
- vital signs (heart rate, blood pressure)
- physiological_coherence_score
- expected plausibility band
Required outputs
- plausibility_decay_flag
- decay_type
- modality_conflict_label
- plausibility_drop_score
Decay types
Examples:
perfusion-discordant
perfusion looks normal but FFR implies severe ischemiawall-motion-discordant
wall motion abnormal but FFR looks normalmulti-modality-conflict
multiple modalities disagree with FFRborderline-mismatch
small but clinically relevant mismatch
Why cardiologists care
A stable-looking number
can still be wrong for the patient.
This dataset flags when:
- physiology and prediction stop matching
- the reading needs verification or escalation
Evaluation
The scorer checks that the response includes:
- a binary decay flag
- a named decay type
- a conflict label
- a 0 to 1 plausibility drop score
