Clinical Knowledge Graphs for Chest X-Ray Device Reasoning

The paper introduces an uncertainty‑aware clinical knowledge graph for chest X‑ray device reasoning, capturing device instances, tip estimates, placement assessments, provenance, report events, and temporal links as interconnected evidence. The graph builder processes 30,083 studies from 3,255 patients, producing 914,632 evidence nodes and 884,549 typed relationships, while preserving detailed uncertainty and provenance information for each predicted device. The authors also outline typed data contracts, uncertainty representations, abstention rules, report‑image grounding, and longitudinal query mechanisms, though the current analysis is post‑hoc descriptive and does not yet demonstrate clinical utility.

CXR-Retrieve: Compositional Text-to-Image Retrieval in Chest Radiography

Large chest radiography archives are difficult to search because most studies are paired only with free-text reports rather than structured clinical annotations. Vision-language models offer a natural interface for text-to-image retrieval, but current biomedical models are primarily optimized for report-to-image matching rather than for satisfying short clinical search queries.

Graph-Augmented Topological Internalization with Dual-Stream Classifiers for Medical Report Generation

The paper introduces GDMRG, a Graph-Augmented Dual-Stream Medical Report Generation framework that incorporates a Topological Knowledge Internalization module using a Graph Convolutional Network to encode disease co-occurrence priors. It employs a dual-stream classifier—one branch generating diagnostic prompts under topological constraints and an auxiliary branch dynamically calibrating decision boundaries for imbalanced samples—alongside a Diagnosis-Guided Spatial Attention mechanism to align visual features with clinical semantics. Experiments on MIMIC-CXR show competitive clinical efficacy and natural language fluency, with strong zero-shot performance on IU X-Ray.

ZAGNet: Zone-Aware Graph Aggregation Network for Patient-Level Lung Ultrasound Diagnosis

ZAGNet is a Zone‑Aware Graph Neural Network that models temporally tracked lung ultrasound findings as graph nodes linked by anatomical zone adjacency, enabling contextual propagation via a graph transformer and a virtual global node for patient‑level diagnosis. It handles missing zones by operating on a flexible graph structure, and outperforms traditional max/mean pooling on a multicenter dataset of 714 subjects, achieving AUCs of 0.803 for consolidation and 0.893 for pleural effusion. The study demonstrates that graph‑based inter‑zone reasoning improves automated patient‑level LUS assessment.
