Auditable CT Phenotyping Through Report-derived Radiological Observations

The study introduces Auditable CT Phenotyping (ACT), a method that uses report-derived radiological observations to predict 221 electronic-health-record phenotypes from CT scans. Trained on 38,317 patients and evaluated on 25,183 held‑out patients, ACT outperformed five vision‑language baselines and CT‑CLIP in both zero‑shot and linear probing settings. Analysis of the model’s probes revealed that a small set of observations, such as aortic and coronary calcification, dominated top predictions, but restricting the observation bank to clinician‑specified evidence improved interpretability without sacrificing accuracy.
