Solve the Missing First Step: Can VLMs Standardize Raw Heterogeneous Medical Data?
The pith
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
Core claim
Current vision-language models can often emit schema-valid JSON, yet they fail to complete the full pipeline of source identification, visual conversion, annotation alignment, and content-faithful structuring from raw heterogeneous medical folders. On MDS-Bench the best model reaches only 48.6 percent end-to-end strict success, so raw medical data standardization remains unsolved and limits real-world medical AI.
What carries the argument
MDS-Bench: 1,939 source-traced standardization tasks scored with an eleven-metric protocol whose strict end-to-end pass requires a valid image-JSON pair, exact source match, schema validity at least 0.85, and semantic and content-fidelity scores at least 0.5.
Load-bearing premise
The claim rests on treating human-verified ground truth from public imaging datasets, scored with the authors’ chosen end-to-end thresholds, as a fair proxy for real clinical raw-data environments with private systems and incomplete metadata.
What would settle it
A controlled re-evaluation on private hospital folders (or a public subset with deliberately incomplete metadata) that drives the best model’s end-to-end rate well above or well below 48.6 percent under the same gates would confirm or undermine the bottleneck claim.
Editorial analysis
A structured set of objections, weighed in public.
Referee Report
Summary. The paper argues that medical VLM evaluation has skipped an upstream step: converting raw, heterogeneous clinical dataset folders into source-grounded, VLM-ready image–JSON units. It introduces MDS-Bench (1,939 samples over ~100 public imaging datasets spanning classification, segmentation, and detection; diverse modalities and raw formats) and an eleven-metric protocol that gates field scores on source matching and reports structure, semantic, content, metadata, and joint success, including End-to-End Strict Pass (E2E; Eqs. 2–3). Nine agentic VLMs are evaluated under a staged standardization workflow; Gemini 3 Flash is strongest yet reaches only 48.6% E2E (Table 1), with failures concentrated in content fidelity and joint pipeline success (Table 2, Fig. 6). An inference-strategy ablation (Fig. 7) shows validation-guided complete-candidate selection improves E2E but does not close the gap. The authors conclude that raw medical data standardization is a critical bottleneck for deploying medical VLMs in practice.
Significance. If the empirical picture holds, the work usefully reframes medical multimodal evaluation around a previously under-measured prerequisite rather than only post-curation diagnosis or VQA. Strengths include: a large multi-dataset construction with human verification of source-grounded targets; source matching as a gate for field metrics (methodologically appropriate); equal-weight dataset aggregation; task- and modality-wise breakdowns; error attribution by capability group; and a controlled inference-strategy ablation. The staged agentic task definition and the SCJ/E2E joint metrics make the bottleneck claim falsifiable in a way that schema-only structured-output benchmarks do not. The Limitations section is appropriately candid about public-dataset scope and residual annotation risk. These contributions are of clear interest to medical AI and multimodal agent evaluation, provided the headline quantitative claims are shown to be robust to scoring choices and the agent protocol is fully specified for reproduction.
major comments (3)
- [§3.4 Evaluation Protocol; Eqs. (2)–(3); Table 1] §3.4, Eqs. (2)–(3), Table 1: The central quantitative claim (48.6% E2E for Gemini 3 Flash; Abstract) is defined by three free gates—gi ≥ 0.85, qi ≥ 0.5, fi ≥ 0.5—plus exact source match. The manuscript motivates gi ≥ 0.85 as avoiding over-penalizing minor schema defects, but does not report sensitivity of E2E (or SCJ) under alternative thresholds (e.g., gi ∈ {0.7, 0.9, 1.0}, qi/fi ∈ {0.4, 0.6}). Because SV is already high (80–88%) while joint scores are low, the absolute “bottleneck” percentage may be partly threshold-driven. A short sensitivity table or curve for the top models is needed so readers can separate robust pipeline failure from cutoff choice; without it, the headline number is under-supported even if the qualitative structure–joint gap remains.
- [§4.1 Experimental Setup; §3.3 Staged Reasoning Design] §4.1 Experimental Setup: The evaluation is agentic (file inspection, tools, executable scripts; §3.3), yet the paper does not specify the shared coding-agent environment, available tools, prompt/scaffold text beyond the staged workflow sketch, interaction budget (turns/tool calls), timeout, or whether models may install packages or only use a fixed sandbox. These details are load-bearing for a benchmark whose scores depend on multi-step file recovery and conversion. Please add a reproducible agent protocol (or release the exact harness) so that the 48.6% E2E and model ranking can be re-run under matched conditions.
- [Abstract; §1 Introduction; Limitations] Abstract / §1 / Limitations: The claim that standardization is a “critical bottleneck … in real practice” is only partially supported by evidence from public research datasets with verified folder layouts. Limitations correctly notes missing PACS/EHR linkage, access control, and incomplete clinical metadata. The abstract and conclusion should be tightened to match the evidence (e.g., bottleneck on heterogeneous public raw imaging archives under the defined schema), or the authors should add a small clinical-style stress subset (messy paths, missing sidecars, multi-study folders) that tests the same metrics. As written, the leap from MDS-Bench to clinical deployment overstates what Table 1 measures.
minor comments (6)
- [Figure 5] Figure 5 heatmaps use hard-to-read glyph encodings in the manuscript text dump; ensure the camera-ready figure has clear numeric annotations or a readable colorbar so per-task differences are inspectable without the appendix tables.
- [Figure 6; §4.2] Figure 6 capability weights (0.15/0.20/0.25/0.10/0.30) are free parameters; state that Wgt is a presentation device and that model ranking under equal metric weights (or leave-one-group-out) is unchanged, or move Wgt to appendix.
- [Figure 5; Appendix B.2] Detection has only six datasets (Tables 8–9); the paper already cautions this is indicative—please flag the same caveat in the main-text discussion of Figure 5 so readers do not over-read detection rankings.
- [§3.2 Benchmark Construction; Limitations] Ground-truth construction (§3.2): briefly quantify human verification effort (e.g., fraction of fields corrected from model drafts, inter-annotator check on a subset) to bound residual annotation error mentioned in Limitations.
- [Abstract; §3.2] Minor consistency: Abstract says “manually annotate 1,939” while §3.2 describes model-assisted drafts plus human verification—align wording so the construction pipeline is unambiguous.
- [Appendix C.6; Eq. (15)] Eq. (15) MSJ uses a geometric mean of metadata components times CF; a one-sentence justification for the geometric mean (vs. product or min) would help readers interpret Table 1’s MSJ column.
Circularity Check
Empirical benchmark against human-verified external targets; no derivation that reduces predictions to inputs by construction.
full rationale
MDS-Bench is an evaluation paper, not a first-principles derivation. Models receive raw dataset folders and are scored against independently constructed, source-traced ground truth (manual identification of sources/labels/masks plus human verification of model-assisted drafts; §3.2). The headline 48.6% E2E figure (Abstract; Table 1; Eqs. 2–3) is the fraction of samples that simultaneously meet externally defined gates (valid image–JSON pair, exact source match si=1, gi≥0.85, qi≥0.5, fi≥0.5) relative to that verified target—not a quantity fitted from the same models’ outputs or defined in terms of the claim being proved. Schema validity is high while joint metrics are low precisely because the protocol does not credit schema-only outputs; that gap is measured, not assumed. Self-citations are ordinary related-work pointers and do not load-bear a uniqueness or ansatz claim. Threshold sensitivity of E2E and residual annotation risk (Limitations) are robustness/correctness concerns, not circular reductions. No self-definitional loop, fitted-input-as-prediction, or self-citation uniqueness chain is present.

As vision-language models (VLMs) are increasingly applied to medical AI, existing benchmarks mainly focus on evaluating their diagnosis ability over given medical images and texts, implicitly assuming that standardized medical images, texts or question-answer pairs are already prepared. However, this assumption does not hold when we apply VLMs in real clinical practice, where medical data is often raw, heterogeneous, and fragmented across different sources. In this paper, we study this missing step, i.e., raw medical data standardization. Specifically, models are given raw dataset folders and evaluated on their ability to identify source formats, convert raw medical images into VLM-compatible visual inputs, extract relevant textual information, and organize the results into structured image-text pairs. To construct this Medical Data Standardization Benchmark (MDS-Bench), we manually annotate 1,939 raw medical data standardization tasks covering diverse clinical practice, radiology modalities, annotation formats, and directory layouts. Extensive experiments show that even the best performing VLMs, i.e., Gemini 3 Flash, achieve only 48.6% end-to-end success rate. Our research highlights raw medical data standardization as a critical bottleneck for medical AI diagnosis in real practice.
