CMR-EXTR: Structured Extraction from Cardiac MRI Reports
CMR-EXTR is a lightweight framework for converting free-text cardiac magnetic resonance (CMR) reports into structured, auditable data with per-field confidence estimation. It was introduced in the paper Uncertainty-Aware Structured Data Extraction from Full CMR Reports via Distilled LLMs.
Overview
The model is designed to support cohort assembly, longitudinal data curation, and clinical decision support in real-world clinical workflows. It performs structured information extraction from reports and assigns confidence scores to each extracted field, enabling efficient human review and quality control.
Key Features
- Structured Extraction: Converts free-text CMR reports into predefined structured fields
- Per-field Confidence: Provides uncertainty estimates for each extracted variable
- Offline Inference: Fully deployable without external API dependencies
- Efficient Design: Lightweight student model distilled from a larger teacher model
Code
The official implementation is available on GitHub:
CMR-EXTR
Method Summary
CMR-EXTR is built on a teacher–student distillation framework:
- A large teacher model generates high-quality structured outputs
- A compact student model (based on Llama-3.2-1B) is trained to replicate these outputs efficiently
- The student model supports fast and fully offline inference
Uncertainty estimation integrates three complementary principles:
- Distribution Plausibility — evaluates whether predictions follow expected value ranges
- Sampling Stability — measures consistency under stochastic decoding
- Cross-field Consistency — enforces logical relationships across extracted variables
