Learning to Measure and Diagnose: A Clinical-Dictionary Radiomic Bottleneck Model for Thyroid Nodule Classification

Read the original on arXiv Computer Vision →

The paper introduces a clinical‑dictionary radiomic bottleneck model for classifying thyroid nodules from ultrasound images. It combines Family‑Aware Radiomic Learning to estimate measurements across feature families with Fidelity‑Guided Bottleneck Modeling to jointly optimize measurement estimation and classification while preserving measurement fidelity. The model decomposes decision evidence through a linear classifier, mapping feature contributions to clinical dictionary categories, and demonstrates competitive performance on ThyroidXL and TN3K datasets with interpretable case studies.

Radiomics-Based Thyroid Nodule Classification with Label-Conditional Conformal Prediction

The paper presents a radiomics-based approach for classifying thyroid nodules using ultrasound images. It extracts quantitative features with PyRadiomics and employs a Generalized Additive Model (GAM) chosen for its balance of performance and interpretability, achieving an AUC of 0.89, sensitivity of 0.83, and specificity of 0.82 on a public dataset. To provide uncertainty estimates, Cross-Conformal Prediction with label-conditional guarantees is applied, allowing 63% of test nodules to receive a confident single-label prediction while the remaining 37% are referred to clinicians.

CMCNet: Aligning Ultrasound Image Embeddings with Textual TI-RADS Representations for Fine-Grained Thyroid Classification

arXiv:2608. 13939v1 Announce Type: cross Abstract: Ultrasound is the primary imaging modality for assessing thyroid nodules, and the ACR TI-RADS framework standardizes diagnosis through five ultrasound feature categories that are aggregated into five risk levels (TR1-TR5).

Calibrated Selective Prediction Using Deep Ensembles for ROI-Based Thyroid Nodule Ultrasound Classification Under Dataset Shift: A Retrospective Evaluation

arXiv:2607. 12075v1 Announce Type: cross Abstract: Background: Deep learning models can classify thyroid nodules on ultrasound, but reliable clinical decision support also requires calibrated probabilities, uncertainty estimation, and selective referral, particularly under dataset shift.

TAM-Chain: Multi-Scale Thyroid Cytology Classification via Absorbing Markov Chains and Shannon Entropy Uncertainty Quantification for False-Negative Suppression and Domain-Shift Adaptation

TAM-Chain is a multi‑scale thyroid cytology classification framework that uses Absorbing Markov Chains and Shannon Entropy to quantify uncertainty and dynamically decide when to stop processing and refer to a specialist. It processes images at 10×, 20×, and 40× magnifications, achieving a Macro F1 score of 0.9741 on an internal test set with a 0 % false‑negative rate, and maintains a Macro F1 of 0.7026 on an external validation set with severe domain shift. The method outperforms single‑magnification baselines by adaptively adjusting stopping steps and triggering specialist referrals, thereby reducing critical diagnostic errors.
