New framework extracts CMR reports with confidence scores

Researchers have developed CMR-EXTR, a new framework designed to convert free-text cardiac magnetic resonance (CMR) reports into structured data. This system not only extracts information but also assigns confidence scores for each data field, aiding in quality control. The framework utilizes a teacher-student distillation pipeline for offline inference and integrates three principles for uncertainty estimation: distribution plausibility, sampling stability, and cross-field consistency. Experiments indicate CMR-EXTR achieves 99.65% variable-level accuracy, marking it as the first CMR-specific extraction system with built-in confidence estimation. AI

    Uncertainty-Aware Structured Data Extraction from Full CMR Reports via Distilled LLMs

    Converting free-text cardiac magnetic resonance (CMR) reports into auditable structured data remains a bottleneck for cohort assembly, longitudinal curation, and clinical decision support. We present CMR-EXTR, a lightweight framework that converts free-text CMR reports into struc…
