01Reporting architecture

Report Formats

RheumaView always produces one canonical report first — the validator-confirmed Gold Standard read. Every other format is derived strictly from it: the Standard and Concise clinical formats are condensations at the level of detail the user requests, and the optional analytic addendum is an extension built on the same canonical read. Findings never change between derivations, and all three clinical formats summarize complex longitudinal cases in full. The formats differ in concentration — and in whether they carry an EMR-ready summary and the optional addendum — not in the case complexity they handle.

Shared core — common to all formats

The platform always generates the canonical validated read — Gold Standard (READY+) — first, then derives every other format from it; no derivative can modify, reinterpret, or override it. The read is deterministic: identical input yields identical structured output on re-evaluation. Adequacy is always evaluated; if a study is limited or inadequate, a data-limited statement is surfaced. Whether an adequacy / data-needs block is shown is a setting, not a mandatory section. The three clinical formats correspond to the case-library labels READY+ (Gold), READY (Standard), READY− (Concise) — each more concentrated, not less capable. The EMR-ready summary and the optional research addendum attach to Gold (READY+) only.

Gold Standard
Most complete clinical report. Per-region findings, per-joint/per-level grading, quantified laterality, prior comparison, EMR-ready summary. The only tier that carries the optional addendum.

Format 01 · READY+ · most complete clinical output Gold Standard

The reference layer for all other formats. Per-region structured findings carry per-joint / per-level grading, quantified laterality, pattern separation with explicit mimic-control, full prior comparison (including numeric deltas where matched priors exist), an adequacy / data-needs block, and an EMR-ready summary suitable for direct inclusion in the record. Gold is the only tier that carries an EMR-ready summary and the only tier the optional research addendum attaches to.

See Gold Standard in a live case →
Format 02 · READY · concentrated clinical read Standard

A more concentrated clinical report. The factual core, findings, grading, and comparison are identical in substance to Gold Standard; the differences are concentration (a tighter surface), the absence of an EMR-ready summary, and the absence of the optional research addendum. It handles complex longitudinal cases as fully as Gold — it simply presents them more tightly.

When to use

  • Routine follow-up and outpatient workflow
  • Complex longitudinal cases, read concentrated
  • When no EMR summary or addendum is needed

Primary audience

  • Radiologists in routine workflow
  • Referring clinicians

Contains

  • Per-region structured findings
  • Per-joint / per-level grading
  • Comparison language (preserved)
  • Adequacy statement (when applicable)
  • Impression

Differs from Gold

  • More concentrated surface
  • No EMR-ready summary
  • No optional research addendum
  • Same findings and case handling
See Standard in a live case →
Format 03 · READY− · maximally concentrated Concise

The most concentrated clinical format: principal structural findings and impression, without the expanded quantitative layer. It still summarizes complex longitudinal cases in full — at maximum concentration. An adequacy statement is surfaced even at minimum depth whenever the study is limited.

When to use

  • Rapid triage and pre-read
  • Hand-off and consultation summaries
  • Maximally concentrated summary of complex cases

Primary audience

  • On-call and triage radiologists
  • Clinicians needing a brief read

Contains

  • Principal structural findings
  • Impression
  • Adequacy statement (if study limited)

Differs from Standard

  • Maximum concentration
  • Findings reduced to principal items
  • Impression-led

03Same finding, three depths

One region from a live case — the knees of RV-009, a longitudinal study with priors at 2022 and 2024 — rendered at each clinical depth. The finding is the same; the surface contracts sharply as depth decreases.

Gold StandardREADY+per-compartment grades + multi-prior deltas

Bilateral knees: minimal tibial-eminence sharpening; tiny left lateral femorotibial marginal spurring, trace lateral irregularity on the right. Femorotibial JSN: medial 0/0, lateral 0–trace 1; trace bilateral patellofemoral spurring (0–trace 1). KL/OARSI ~1 bilaterally. No effusion or destructive erosion on the provided views. Chronic asymmetric proximal fibular cortical remodeling, left greater than right (fusiform thickening, focal cortical buttressing). Versus 2022/2024 priors: ΔJSN 0 · Δosteophytes 0 · ΔKL-OARSI 0/0; fibular remodeling stable.

StandardREADYnarrative + comparison

Minimal bilateral knee osteoarthritic change (approximately KL/OARSI grade 1), with tiny lateral-compartment and patellofemoral spurring; no effusion or destructive erosion. Chronic asymmetric proximal fibular remodeling, greater on the left, stable. No measurable interval progression versus the 2022/2024 priors.

ConciseREADY−impression only

Minimal bilateral knee osteoarthritis, stable; stable chronic left-greater-than-right proximal fibular remodeling.

04Output customization

Within any clinical format, the report can be configured to the reading task. Customization is an overlay on presentation and reporting policy — it changes what the report surfaces and how, not how the platform derives the read. The validated structural read, the deterministic core, and the canonical generation order are unchanged.

Formatting & layout
Section presentation, length, and report structure for the destination workflow.
Level of detail
How much of the structured read is surfaced, independent of the chosen format.
Sensitivity
Standard, high-sensitivity, or very-high-sensitivity reads tuned to the task — e.g. inflammatory or oncologic.
Detection thresholds
The thresholds at which structural findings and interval changes are reported.
Confidence policy
Whether low-confidence findings are reported, or output is restricted to moderate- and high-confidence findings — the per-finding confidence labels shown above are what this governs.
Comparison depth
How much prior-study comparison and delta reporting is surfaced in the output.

An overlay, not a change to the platform

Customization governs which findings, and how much of them, the report presents. The same input still yields the same validated structured source; the underlying read, its lineage, and the way the platform works are unchanged.

Cross-Modal Final Analytic Synthesis

This rebuilt addendum supports a stable non-ankylosing bilateral SI structural pattern on longitudinal radiographs, with mild symmetric bilateral SI marrow-edema-like MRI signal but no MRI or XR erosions and no ankylosis. The dominant chronic structural burden remains degenerative, centered in the lower cervical and especially thoracolumbar/upper lumbar spine, while the lumbar MRI shows only mild focal L5-S1 degenerative disease. Neurophysiologic testing adds a dissociation layer: moderate bilateral carpal tunnel syndrome is present without electrodiagnostic evidence of cervical radiculopathy, and lower-extremity EMG/NCS is normal despite mild L5-S1 morphology. Overall composite profile: mixed but degenerative-predominant structural phenotype, stable over the matched SI radiographic interval, with low-grade MRI SI inflammatory/reactive signal and no destructive progression.
