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.

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.

Mediastinal mass incidental finding detected during LDCT screening. Multiple masses can be recorded as separate observation instances. At least one of size, changed density, or calcification should be documented per ADP dataset section 1.2.2.2 item 4.

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.
