In a retrospective two-center study, a CT habitat-based radiomics model combined with clinical factors predicted occult central node metastases in papillary thyroid cancer, achieving an AUC of 0.878 on external validation.
A deep learning MRI system distinguished six glioma/glioneuronal tumor subtypes with external test AUCs 0.69–0.92 and accuracy 0.81–0.95 in 1,844 patients, best for pilocytic astrocytoma versus pleomorphic xanthoastrocytoma (AUC 0.95).
Brain 3D-FLAIR showed near-perfect agreement (Cohen's Kappa 0.961) with dedicated optic nerve 2D-STIR in detecting optic nerve lesions in clinically isolated syndrome, with accuracy 93.1% vs 91.2%. It may serve as an alternative in routine brain MRI.
CoilDrop-MRI, a self-supervised reconstruction using coil-wise dropout, matches supervised quality without fully sampled training data. It outperforms existing self-supervised methods across multi-site, multi-field-strength (0.3T-3T) and multi-modality MRI.
