Models

FindingModelBase

Basics of a finding model, including name, description, and attributes.

Properties:

• name: The name of the finding.
• description: A brief description of the finding. Optional.
• synonyms: Alternative names or abbreviations for the finding. Optional.
• tags: Keywords or categories associated with the finding. Optional.
• attributes: A collection of attributes objects associated with the finding.

Methods:

• as_markdown(): Generates a markdown representation of the finding model.

FindingModelFull

Uses FindingModelBase, but adds contains more detailed metadata:

• Requiring IDs on models and attributes (with enumerated codes for values on choice attributes)
• Allows index codes on multiple levels (model, attribute, value)
• Allows contributors (people and organization)

FindingInfo

Information on a finding, including description and synonyms, can add detailed description and citations.

Properties:

• name: The name of the finding.
• synonyms: Alternative names or abbreviations for the finding. Optional.
• description: A brief description of the finding. Optional.
• detail: A more detailed description of the finding. Optional.
• citations: A list of citations or references related to the finding. Optional.

Index

For a directory structured with a defs sub-directory containing definitions files (e.g., in a clone of the Open Imaging Finding Model repository), creates/maintains an index as a JSONL file index.jsonl in the base directory (alongside the defs directory).

from findingmodel.index import Index

index = Index() # Initialize with base directory; will find existing JSONL
print(await index.count())

metadata = index.get("abdominal aortic aneurysm") # Lookup by ID, name, synonym
print(metadata.model_dump())
# > {'attributes': [{'attribute_id': 'OIFMA_MSFT_898601',
# >                  'name': 'presence',
# >                  'type': 'choice'},
# >                 {'attribute_id': 'OIFMA_MSFT_783072',
# >                  'name': 'change from prior',
# >                  'type': 'choice'}],
# >  'description': 'An abdominal aortic aneurysm (AAA) is a localized dilation of '
# >                 'the abdominal aorta, typically defined as a diameter greater '
# >                 'than 3 cm, which can lead to rupture and significant '
# >                 'morbidity or mortality.',
# >  'filename': 'abdominal_aortic_aneurysm.fm.json',
# >  'name': 'abdominal aortic aneurysm',
# >  'oifm_id': 'OIFM_MSFT_134126',
# >  'synonyms': ['AAA'],
# >  'tags': None}

results = index.search("abdominal") # Returns matching names or synonyms

See example usage in notebook.

Tools

All tools are available through findingmodel.tools. Import them like:

from findingmodel.tools import create_info_from_name, add_details_to_info
# Or import the entire tools module
import findingmodel.tools as tools

Note: Previous function names (e.g., describe_finding_name, create_finding_model_from_markdown) are still available but deprecated. They will show deprecation warnings and point to the new names.

create_info_from_name()

Takes a finding name and generates a usable description and possibly synonyms (FindingInfo) using OpenAI models (requires OPENAI_API_KEY to be set to a valid value).

from findingmodel.tools import create_info_from_name

await create_info_from_name("Pneumothorax")

>>> FindingInfo(name="pneumothorax", synonyms=["PTX"], 
  description="Pneumothorax is the...")

add_details_to_info()

Takes a described finding as above and uses Perplexity to get a lot of possible reference information, possibly including citations (requires PERPLEXITY_API_KEY to be set to a valid value).

from findingmodel.tools import add_details_to_info

finding = FindingInfo(name="pneumothorax", synonyms=['PTX'],
    description='Pneumothorax is the presence...')

await add_details_to_info(finding)

>>> FindingInfo(name='pneumothorax', synonyms=['PTX'], 
 description='Pneumothorax is the...'
 detail='## Pneumothorax\n\n### Appearance on Imaging Studies\n\nA pneumothorax...',
 citations=['https://pubs.rsna.org/doi/full/10.1148/rg.2020200020', 
  'https://ajronline.org/doi/full/10.2214/AJR.17.18721', ...])

create_model_from_markdown()

Creates a FindingModel from a markdown file or text using OpenAI API.

from findingmodel.tools import create_model_from_markdown, create_info_from_name

# First create basic info about the finding
finding_info = await create_info_from_name("pneumothorax")

# Then create a model from markdown outline
markdown_outline = """
# Pneumothorax Attributes
- Size: small, moderate, large
- Location: apical, basilar, complete
- Tension: present, absent
"""

model = await create_model_from_markdown(
    finding_info, 
    markdown_text=markdown_outline
)

create_model_stub_from_info()

Given even a basic FindingInfo, turn it into a FindingModelBase object with at least two attributes:

• presence: Whether the finding is seen
  (present, absent, indeterminate, unknown)
• change from prior: How the finding has changed from prior exams
  (unchanged, stable, increased, decreased, new, resolved, no prior)

from findingmodel.tools import create_info_from_name, create_model_stub_from_info

# Create finding info
finding_info = await create_info_from_name("pneumothorax")

# Create a basic model stub with standard presence/change attributes
stub_model = create_model_stub_from_info(finding_info)
print(f"Created model with {len(stub_model.attributes)} attributes")

add_ids_to_model()

Generates and adds OIFM IDs to a FindingModelBase object and returns it as a FindingModelFull object. Note that the source parameter refers to the source component of the OIFM ID, which describes the originating organization of the model (e.g., MGB for Mass General Brigham and MSFT for Microsoft).

from findingmodel.tools import add_ids_to_model, create_model_stub_from_info

# Create a basic model (without IDs)
stub_model = create_model_stub_from_info(finding_info)

# Add OIFM IDs for tracking and standardization
full_model = add_ids_to_model(stub_model, source="MSFT")
print(f"Model ID: {full_model.oifm_id}")

add_standard_codes_to_model()

Edits a FindingModelFull in place to include some Radlex and SNOMED-CT codes that correspond to some typical situations.

from findingmodel.tools import add_standard_codes_to_model

# Add standard medical vocabulary codes
add_standard_codes_to_model(full_model)
print("Added standard RadLex and SNOMED-CT codes")
