Lithuanian Lung Cancer Implementation Guide
0.0.1 - ci-build
Lithuanian Lung Cancer Implementation Guide, published by Lithuanian Medical Library. This guide is not an authorized publication; it is the continuous build for version 0.0.1 built by the FHIR (HL7® FHIR® Standard) CI Build. This version is based on the current content of https://github.com/HL7LT/ig-lt-lung/ and changes regularly. See the Directory of published versions

This page provides a list of the FHIR artifacts defined as part of this implementation guide.
These define forms used by systems conforming to this implementation guide to capture or expose data to end users.
| Questionnaire: LDCT ESPBI Form (LT Lung) |
Structured data-capture form for low-dose chest computed tomography (LDCT) reporting based on ADP Table 7.1 (MDKT dataset). |
| Questionnaire: Pre-LDCT Questionnaire (LT Lung) |
Structured data-capture form for the pre-examination questionnaire before LDCT screening, based on ADP Table 7.2. Captures functional status, prior examinations, anthropometrics, smoking history, and current diagnoses. |
These define constraints on FHIR resources for systems conforming to this implementation guide.
| Incidental Finding (LT Lung) |
Significant incidental finding detected during low-dose chest computed tomography (LDCT) screening. Covers both pulmonary incidental findings (emphysema, bronchiectasis, pleural changes, etc.) and extra-pulmonary findings (coronary calcification, aortic aneurysm, mediastinal mass, etc.) as defined in the MDKT dataset sections 1.2.2.1 and 1.2.2.2. |
| LUNG-RADS Assessment (LT Lung) |
LUNG-RADS assessment category assigned to a low-dose chest CT (LDCT) screening examination in the Lithuanian lung cancer early diagnosis programme. The observation represents the final radiological assessment that determines the follow-up recommendation and screening pathway. SNOMED CT code 1362105002 is used for the observable concept 'Lung Imaging Reporting and Data System category (observable entity)'. The actual assessment value is represented using a local code system for the main category values 0, 1, 2, 3, 4A, 4B, and 4X, because separate SNOMED CT codes for those category values are not provided in the source dataset. The optional S modifier is represented as a component. |
| Lung Composition (LT Lung) |
Lung-specific imaging composition extending the base imaging composition with lung-specific constraints on findings, impression, and recommendation sections. Designed for use in the Lithuanian lung cancer prevention programme LDCT screening. |
| Lung LDCT Report (LT Lung) |
Overall lung LDCT diagnostic report covering the low-dose chest computed tomography screening pathway. Wraps a LungCompositionLtLung and aggregates structured results including LUNG-RADS assessments, pulmonary nodule observations, incidental findings, and follow-up recommendations. |
| Lung Screening Recommendation (LT Lung) |
Recommendation for follow-up or referral after low-dose chest CT (LDCT) screening examination in the Lithuanian lung cancer early diagnosis programme. This observation captures the recommended next action following the final LUNG-RADS assessment. SNOMED CT code 424900004 is used for the observation concept 'Recommendation - action (qualifier value)'. The actual recommendation value is represented using a local code system, because the source dataset provides programme-specific recommendation options. |
| 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. |
These define sets of codes used by systems conforming to this implementation guide.
| Finding Density |
Radiologic density types of a lesion. |
| FindingMultiplicityVS | |
| Incidental Finding |
Significant incidental findings in the chest and abdominal areas detected during low-dose chest computed tomography (LDCT) screening. |
| LUNG-RADS Assessment Category |
Allowed primary LUNG-RADS assessment categories used in the Lithuanian lung cancer early diagnosis programme. |
| LUNG-RADS Assessment Modifier Codes |
Allowed LUNG-RADS assessment modifier codes used in the Lithuanian lung cancer early diagnosis programme. |
| Lung Lobe |
Allowed lung lobe body structure codes for localisation of pulmonary nodules in the Lithuanian lung cancer early diagnosis programme. |
| Lung Screening Recommendation Value Set |
Allowed recommendation codes used in the Lithuanian lung cancer early diagnosis programme for follow-up and referral decisions. |
| Lymph Node Location | |
| Pulmonary Nodule Morphology Features |
Allowed morphology characteristics for pulmonary nodules in the Lithuanian lung cancer early diagnosis programme. |
| Pulmonary Nodule Type |
Allowed pulmonary nodule type values used in the Lithuanian lung cancer early diagnosis programme. |
These define new code systems used by systems conforming to this implementation guide.
| LUNG-RADS Assessment Categories |
Main LUNG-RADS assessment categories used in the Lithuanian lung cancer early diagnosis programme. These codes represent the primary final assessment category assigned to the low-dose chest CT screening examination. |
| LUNG-RADS Assessment Modifier |
Additional modifier used together with the main LUNG-RADS assessment category in the Lithuanian lung cancer early diagnosis programme. The modifier S indicates clinically significant incidental findings that contribute to the overall assessment string, for example 0S or 4AS. |
| Lung Screening Recommendation Codes |
Recommendation codes used in the Lithuanian lung cancer early diagnosis programme for follow-up and referral actions after LUNG-RADS assessment. These codes represent the recommended next clinical action based on the radiological conclusion and programme rules. |
| Lung questionnaire answer options |
Illustrative answer option codes for ESPBI questionnaire forms used in the Lithuanian lung cancer prevention programme. |
| Pulmonary Nodule Observation Component Codes |
Local component codes for pulmonary nodule observation elements used in the Lithuanian lung cancer early diagnosis programme when no suitable SNOMED CT code is available in the source dataset. |
| Pulmonary Nodule Type Local Codes |
Local codes for pulmonary nodule types used in the Lithuanian lung cancer early diagnosis programme when no suitable SNOMED CT code is available in the source dataset. |
