Performance of artificial intelligence versus clinician left-ventricular segmentation of cardiac MRI for mortality prediction: a retrospective, multicentre, prognostic study
Background: Ejection fraction, a key measure of cardiac function, is used in health care for clinical decision making and risk stratification. We hypothesised that a deep-learning artificial intelligence (AI) segmentation of ejection fraction obtained from cardiac MRI (CMR) outperforms expert clinician segmentation for the prediction of all-cause mortality. Methods: In this retrospective, multicentre, prognostic study, we studied a cohort of 27 382 consecutive patients who underwent cardiac MRI (CMR) in the UK a…
In 27,382 cardiac MRI patients, AI-derived ejection fraction fit mortality data better and discriminated marginally better than clinician-derived values (C index 0.669 vs 0.637).
The study was retrospective, and the authors state that the AI's potential for first-line measurement with clinician oversight should be investigated in prospective studies.

How to verify without trusting this page
Fetch the canonical text of any version from /api/record/TRV-2026-2347 and hash it yourself — for example shasum -a 256 on the saved canonical field. The result must equal content_hash, and each version’s text ends with prev:followed by the prior version’s hash (version 1 chains to 64 zeros). If a single character of any version had been altered since certification, the chain would not reproduce.
