Resource Profile: Pulmonary Nodule (LT Lung)

Pulmonary nodule identified on low-dose chest CT (LDCT) in the Lithuanian lung cancer early diagnosis programme.

One observation represents one pulmonary nodule (Židinys). Multiple nodules are represented as multiple Observation instances.

The observation captures the nodule type, localisation, CT slice number, morphological features, measurements, and optional note.

Usages:

• Refer to this Profile: Lung Composition (LT Lung)
• Examples for this Profile: Observation/observation-pulmonary-nodule-ground-glass-example, Observation/observation-pulmonary-nodule-part-solid-example and Observation/observation-pulmonary-nodule-solid-example

Summary

Mandatory: 4 elements

Structures

This structure refers to these other structures:

• PatientLt (https://hl7.lt/fhir/base/StructureDefinition/patient-lt|0.3.0)
• EncounterLt (https://hl7.lt/fhir/base/StructureDefinition/encounter-lt|0.3.0)
• PractitionerLt (https://hl7.lt/fhir/base/StructureDefinition/practitioner-lt|0.3.0)

Slices

This structure defines the following Slices:

• The element 1 is sliced based on the value of Observation.component
