The TrueDx evidence-rich report

A pathology opinion you can see—not only read.

Representative slide regions, annotations, maps, and measurements connect the written interpretation to visual evidence patients can understand and oncologists can inspect. The reviewing pathologist verifies the relevant findings and remains the diagnostic authority who signs the final report.

What the computational analysis is

An analysis of algorithmic output computed on a whole-slide image. Every generated statement resolves to a named artifact and, where a judgment is proposed, is shown against the field that most supports it and the field that least supports it.

It is not a signed-out diagnosis and carries no diagnostic authority until reviewed by the reporting pathologist.

What “evidence-rich” means

More than a narrative report.

A conventional report records the pathologist's conclusion. An evidence-rich report also presents the computational and visual observations behind that conclusion in a form the care team can inspect.

1Model-derived evidencePredictions, maps, counts, measurements, and representative fields.
2Pathologist interpretationMicroscopic findings, diagnostic reasoning, limitations, and final impression.
3Traceable provenanceModel version, parameters, tissue coverage, artifact lineage, and reviewed regions.
Six evidence layers

One slide, examined from complementary angles.

Each layer answers a different question. None should be treated as a stand-alone diagnosis.

01

Prediction heatmap

Shows where a classification model found evidence supporting—or arguing against—a predicted category across slide patches.

  • Predicted class and calibrated score
  • Spatial attention or evidence map
  • Highest-support and strongest-counterexample fields
02

Nuclei map

Segments individual nuclei and assigns model-derived morphological classes across evaluated tissue regions.

  • Total nuclei and analyzed area
  • Neoplastic, stromal, inflammatory and other classes
  • Counts, proportions, density and heterogeneity
03

Tissue map

Separates tissue architecture into computational regions such as tumor, stroma, inflammation, necrosis, and other tissue.

  • Area fractions and coverage
  • Tumor–stroma ratio
  • Regional distribution and representative fields
04

Biomarker map

Displays predicted marker intensities or phenotypes from a validated in-silico model when that analysis is available.

  • Marker or phenotype distribution
  • Cell counts and regional co-localization
  • Agreement and divergence from morphology
05
Aa

Microscopic findings

Converts relevant visual and quantitative observations into reviewable pathology findings.

  • Cellular composition
  • Tumor-infiltrating lymphocytes
  • Necrosis and tissue architecture
06
↳

Artifact provenance

Records how every model-derived number and image was produced so it can be traced and audited.

  • Model name, version and parameters
  • Analyzed area, tiles, magnification and resolution
  • Artifact dependencies and source regions
Interactive evidence comparison

Move the slider from H&E to model overlay.

Each comparison keeps the original field and generated evidence in the same coordinate system. Drag horizontally to inspect exactly what the model added.

Images are extracted from the supplied de-identified demonstration report. Overlays are model-derived artifacts for pathologist review and are not independent diagnoses.
Ancillary studies

Model-derived studies that extend the microscopic review.

These analyses add structured computational evidence to the case. They are reported separately from the pathologist's final diagnosis and include their own methods, coverage, uncertainty, and limitations.

Study 01Model-derived

Histological subtype — attention-based MIL

An attention-based multiple-instance model over CONCH v1 patch features evaluates the distribution of evidence for candidate histological subtypes.

  • Shows how evidence is distributed across slide patches
  • Identifies the strongest supporting patch
  • Surfaces the strongest field arguing against the prediction
  • Requires confirmation by direct microscopic review
The probability is a model output, not a stand-alone subtype diagnosis.
Study 02Virtual phenotype

In-silico immunophenotype

A virtual multiplex-immunofluorescence model predicts a 20-marker panel from H&E and maps predicted phenotypes back to previously segmented nuclei.

Pathologist impression

Invasive carcinoma is identified in the reviewed material.

Final subtype, grade, and biomarker interpretation require direct pathologist review and correlation with validated studies.

The reviewer determines what is diagnostically valid and what must be excluded.

Homegrown models + Agentic Force

Generated, extracted, organized—then clinically reviewed.

Path23's homegrown AI models generate spatial predictions and extract tissue and cellular measurements. Agentic Force coordinates the artifacts, selects traceable supporting and opposing fields, drafts structured findings, and assembles them for review.

The pathologist remains the diagnostic authority.

  • AI outputs are clearly labeled as model-derived
  • Predicted biomarkers are not represented as performed stains
  • Uncertainty, coverage, and limitations remain visible
  • The pathologist may accept, modify, or reject every generated statement
  • Only the reviewed and signed report becomes the clinical opinion
