MS-Exam-Gen is a reproducible framework that builds a source‑grounded multiple‑choice question benchmark for evaluating large language models on knowledge about multiple sclerosis MRI. The pipeline uses expert‑indexed sources, topic induction, evidence‑grounded MCQ generation, automated quality audits, and consistency checks to produce a 3,058‑item benchmark covering 16 topics and 53 subtopics. Evaluation of 12 LLM endpoints on this benchmark revealed a wide accuracy range (89.7% to 46.9%) and identified items frequently missed by models, while audits showed reduced answer cues and position‑sensitivity in scoring.
arXiv:2606. 07721v1 Announce Type: new Abstract: Objectives: Automatic data extraction from free-text radiology reports enables large-scale research, but few studies assessed the performance of large language models (LLMs) on Dutch neuroradiology reports.
An integrated, web‑based platform has been developed to process diffusion‑weighted imaging (DWI) from MR‑guided linear accelerators and provide structured, literature‑grounded clinical interpretations. The system combines a deep‑learning pipeline for distortion correction, denoising, and IVIM/ADC fitting with a retrieval‑augmented generation (RAG) agent that references a curated knowledge base and traces each statement to its source. Independent expert ratings of nine glioblastoma cases showed high scores for clinical reasoning, citation quality, and overall utility, with a mean rating of 4.65 out of 5.

arXiv:2606. 15735v1 Announce Type: cross Abstract: Discharge summaries are crucial clinical documents containing the context of a patient's overall hospital stay, and are routinely reviewed by medical experts for patient readmission, ongoing care, and diagnostic decision-making.
The study evaluates Jev 1.13, a non‑generative model that selects from predefined answer options, on four medical benchmarks: MetaMedQA, PubMedQA, DiagnosisArena‑MCQ, and the NEJM Case Challenges. Jev’s top‑1 accuracy matches GPT‑6 Sol with medium reasoning on PubMedQA but falls behind on MetaMedQA, DiagnosisArena‑MCQ, and NEJM cases. While Jev shows strong calibration on MetaMedQA and is fast and inexpensive, its performance on examination and complex diagnostic tasks is substantially lower, indicating the need for task‑specific validation before clinical deployment.
arXiv:2607. 02175v1 Announce Type: new Abstract: Multiple-choice medical benchmarks are increasingly saturated, and recent rubric-based evaluations such as HealthBench have shown that open-ended clinical performance is far from solved - its "Hard" subset top score remains 32%.
MultiViewDx is a physician‑validated multimodal instruction dataset that links medical imaging studies with patient context and normalizes heterogeneous reports into an evidence‑linked workflow (evidence → findings → differential discussion → diagnosis). The dataset covers a wide range of imaging modalities and uses a unified image‑text retriever to ensure that instruction synthesis is grounded in source‑supported evidence. Fine‑tuned models on MultiViewDx achieve the highest average accuracy on four MedVQA benchmarks and receive the strongest overall rating on JAMA Clinical Challenge cases, with ablations confirming the importance of case‑level multi‑view organization and evidence‑linked reasoning.

The paper introduces a retrieval‑augmented multi‑agent framework that automatically generates instance‑specific evaluation rubrics for medical language models. By retrieving authoritative medical evidence, decomposing it into atomic facts, and combining these with user interaction constraints, the system produces fine‑grained criteria that outperform GPT‑4o on HealthBench and LLMEval‑Med. The generated rubrics also guide response refinement, improving medical LLM output quality by 9.2%.
