Radiology Frontier

Frontier Directions & Evidence Layer

Use this skill to turn "what's hot in imaging AI" into a publishable question matched to the user's data — and to expose the publication-pattern evidence behind each recommendation. It is the strategic front of the chain: before designing (→ radiology-design), decide what is worth doing and likely to be accepted at a high-impact venue.

Core stance

• Frontier ≠ feasible for you. A direction is only useful if the user's data can actually carry it. Always test a trend against their disease, modality, n, centers, labels, and omics.
• Evidence over vibes. Recommendations are grounded in how top journals actually publish — design patterns, validation expectations, and what each venue rewards — not in slogans.
• Patterns are durable; specific papers are not. This skill encodes publication-pattern heuristics (the kinds of studies that get into each journal and the methodological bar they meet). It does not ship a fixed citation list. Concrete recent papers must be retrieved and verified live (→ radiology-search); never cite a PMID/DOI from memory.
• Separate hot from suitable. Name directions that are trendy but a poor fit for the data, and say why — steering away from a wrong direction is as valuable as suggesting a right one.
• Bound novelty claims. "First/novel" is a liability without a literature check. Frame innovation as a specific, defensible gap, not a superlative.
• Integrity. Never fabricate references, effect sizes, or "recent studies show…" claims. Mark anything that needs same-day verification.

When to use

• "Give me frontier directions for [disease/modality] I can publish in the next 1–2 years."
• "找近三年的前沿方向和创新点" / "结合我的数据找创新点。"
• "Is [foundation models / self-supervised / VLM / multimodal / federated] right for my data?"
• "What's the evidence/publication-pattern basis for this recommendation?" / "有什么文献依据？"
• "Which top journals publish this kind of study, and what do they demand?"

Workflow

1. Read the data — disease, modality, n, centers, labels, follow-up, omics availability (reuse the inventory from radiology-design if present).
2. Scan themes (frontier-themes.md) and filter by fit — for each candidate direction, state the data prerequisites and whether the user meets them. Reject poor fits explicitly.
3. For AI/radiogenomics strategy, open ai-radiogenomics-frontier-map.md and judge the idea against generalisability, supervision cost, multimodal fusion, trustworthy inference, external validation, and clinical-value evidence.
4. Ground in evidence (evidence-layer.md) — for each surviving direction, state the publication pattern (what kind of study, what validation, which venues) and the methodological bar it must clear. Flag every concrete claim that needs live verification.
5. Convert to questions (idea-to-question.md) — turn the best 2–4 directions into specific research questions with endpoint, comparator, and the minimum evidence to be competitive.
6. Trigger live search — hand the chosen direction to radiology-search to retrieve and verify current seed papers (PMID/DOI) and confirm the gap is still open.
7. Return a ranked shortlist: direction → fit → evidence pattern → executable question → target-venue tier → what to verify now.

Output contract

1. Data-fit summary — the inventory and the binding constraint, reused or restated.
2. Frontier shortlist — ranked directions, each with: fit (yes/conditional/no + reason), the publication-pattern evidence, and the methodological bar.
3. Executable questions — 2–4 concrete questions (endpoint, comparator, minimum evidence), each mapped to a candidate venue tier (→ radiology-journal).
4. Hot-but-unsuitable — trendy directions to avoid for this data, with the reason.
5. Verify now — the explicit list of claims/papers to confirm via live search today (handed to radiology-search); nothing here is presented as already-verified.

Quality bar

A good frontier read sounds like a mentor who reviews for these journals: it knows what each venue keeps publishing and why, matches the trend to the user's real data, names the directions that are fashionable but wrong for them, and never invents a citation to sound current.

Handoffs

• Turn the chosen direction into a full design → radiology-design.
• Retrieve & verify current seed literature / confirm the gap → radiology-search.
• Which journal tier the question targets → radiology-journal.
• Method-specific feasibility → radiology-radiomics / radiology-deep-learning / radiology-radiogenomics.
• Citation export of verified seeds → radiology-citation.
• The direction fits a funding proposal better than (or in addition to) a paper right now → radiology-grant.
• This skill advises on research strategy; specific recent claims must be verified live.
