MedicalRec: Medical recommender system for image classification without retraining

This study introduces MedicalRec, a medical recommender system for image classification, designed to optimize model selection without the need for extensive retraining. It addresses the computational and energy challenges of model identification by leveraging a publicly available dataset, MedicalRec-Bench, compiled from 3,000 articles and over 5,000 tested model records.

An interpretable and trustworthy AI framework for large-scale longitudinal structure-pain association studies using data from the Osteoarthritis Initiative (OAI)

This research develops an interpretable AI framework combining deep learning-based MRI Osteoarthritis Knee Score (MOAKS) prediction with interpretable statistical modeling to study structure-pain relationships at scale using data from the Osteoarthritis Initiative (OAI). It utilizes deep learning for MOAKS feature prediction from MRIs with uncertainty quantification, followed by a longitudinal latent class mixed model to examine associations between structural abnormalities and knee pain.

Functional MRI Time Series Generation via Wavelet-Based Image Transform and Spectral Flow Matching for Brain Disorder Identification

The paper introduces Dual-Spectral Flow Matching (DSFM), a novel fMRI generative framework that cascades dual frequency representation of BOLD signals with spectral flow matching. This method aims to synthesize high-fidelity fMRI time series to overcome limitations in data availability for brain disorder identification, by replicating complex spatiotemporal dynamics.

MedGemma 1.5 Technical Report

O MedGemma 1.5 4B é um novo modelo que expande as capacidades do MedGemma 1, integrando análise de imagens médicas de alta dimensão (CT/MRI, histopatologia), localização anatômica e compreensão de documentos médicos. Ele demonstra ganhos significativos em precisão de classificação de condições em MRI e CT, e um aumento de 47% no macro F1 para imagens de patologia de lâmina inteira.
