Radiomics offers distinct advantages in quantifying explicit and biologically interpretable features, such as texture heterogeneity and morphological dynamics across different jaw positions. This provides targeted insights into disc displacement mechanisms that end-to-end DL models may learn only implicitly through latent representations.
Five machine learning models—decision tree (DT), K-nearest neighbors (KNN), support vector machine (SVM), random forest (RF), and logistic regression (LR)—were utilized. The fusion radiomics model consistently outperformed single-phase analyses, achieving robust performance with AUCs of 0.889 (training) and 0.874 (validation) for normal vs. abnormal TMJ discrimination.
SHAP analysis revealed non-linear feature contributions to model outputs. The global importance plot identified feature6 (original_gldm_DependenceNonUniformity_RO) as the top contributor, followed by wavelet-derived features18 and feature45. This provides transparency into model decisions.

Enhancing TMJ Diagnosis with ML
Challenge: Traditional TMJ diagnosis relies on subjective interpretation of MRI scans, leading to variability and potential delays, especially for complex conditions like anterior disc displacement with and without reduction (ADDwR/ADDwoR). Accurate differentiation is crucial for treatment planning.
Solution: A machine learning approach integrating multi-phase radiomic features from 3D segmented TMJ disc and condyle structures was developed. Five ML classifiers were trained on a dataset of 382 TMJs to distinguish normal from abnormal joints, and further differentiate between ADDwR and ADDwoR.
Outcome: The fusion radiomics model achieved a peak AUC of 0.889 for normal vs. abnormal TMJ discrimination. It consistently outperformed single-phase models and provided better differentiation between ADDwR and ADDwoR, enabling more precise and personalized treatment strategies. SHAP analysis provided interpretability of feature contributions.
