Rethinking Artificial Intelligence in Medical Imaging: Assumptions, Reality, and Reframing

Jul 29, 2026

This study addresses the structural misalignment between medical imaging AI research and clinical practice, which impedes the translation of algorithmic performance into tangible diagnostic and therapeutic value. The authors systematically identify six dimensions of misalignment across design, evaluation, and decision-making phases and propose a novel paradigm centered on clinicians, emphasizing actionability and multimodal integration. By incorporating multimodal modeling, interpretable interactive design, few-shot domain adaptation, and seamless integration into clinical workflows, the framework aims to develop “agentive, clinician-aligned” AI systems that generate actionable clinical guidance rather than mere predictions. This work offers the first structural analysis of implementation bottlenecks in medical AI and provides a systematic pathway to bridge the gap between artificial intelligence and real-world clinical practice, thereby enabling AI to genuinely support clinical judgment.

UltraVR: A Diagnostic Ultra-Resolution Image-VQA Benchmark for Evidence-Grounded Reasoning

Jun 03, 2026

This work addresses the limited evidence-driven reasoning capabilities of current vision-language models on super-resolution images and the absence of fine-grained evaluation protocols for their reasoning processes. To this end, the authors propose UltraVR, a diagnostic visual question answering benchmark tailored to four domains: surveillance, remote sensing, histopathology, and industrial inspection. UltraVR introduces, for the first time, a structured chain-of-thought annotation scheme comprising step-level questions, intermediate answers, and reasoning labels, enabling diagnostic analysis across the full pipeline—from evidence localization and local perception to final decision-making. Experimental results reveal that state-of-the-art models perform poorly in super-resolution reasoning, with errors predominantly occurring in the initial two stages; notably, downstream reasoning accuracy improves substantially when intermediate visual facts are explicitly provided.

Radiuma: A Unified Zero-Code Executable Graphical Workflow Generator for Reproducible and Shareable Medical Image Analysis and Machine Learning

May 22, 2026

This work addresses the lack of standardized, user-friendly, and reproducible software environments in medical image analysis, which hinders the widespread adoption of advanced methodologies. To overcome this limitation, the authors propose a modular, zero-code platform that enables seamless integration of image reading, visualization, registration, segmentation, radiomics feature extraction, and machine learning through intuitive graphical workflows. The platform allows users to construct, execute, and share end-to-end analysis pipelines without programming expertise. It introduces a unified, executable, and shareable cross-modality workflow system that ensures full transparency and facilitates collaborative reuse across disciplines. Supporting classification, regression, and clustering tasks, the platform significantly enhances analytical consistency, reproducibility, and interdisciplinary collaboration in clinical and translational research, as demonstrated by experimental validation.

Semi-Parametric Bayesian Additive Regression Trees for Risk Prediction with High-Dimensional Epigenetic Signatures and Low-Dimensional Covariates

May 19, 2026

This study addresses the challenge of jointly modeling high-dimensional epigenetic data with low-dimensional covariates while balancing predictive accuracy and interpretability of covariate effects—a task in which traditional Bayesian Additive Regression Trees (BART) suffer from unstable variable selection in high dimensions. The authors propose a semiparametric BART (spBART) framework that incorporates low-dimensional covariates into a parametric component with interpretable coefficients, while flexibly modeling high-dimensional epigenetic features via a tree ensemble, thereby unifying prediction and inference. A novel variable selection strategy combines cross-validated posterior inclusion probabilities with Bayesian false discovery rate control to achieve stable identification of relevant high-dimensional features. Applied to 5hmC data from multiple myeloma patients, spBART yields a parsimonious set of candidate loci and achieves excellent discriminative performance with an AUC of 0.96 on an independent validation set.
