Choice of modality

Projectional radiography ("X-ray") of the chest is central to evaluation of sarcoidosis.[1]

Routine CT scanning adds little to the diagnosis.[1] HRCT of the chest is needed if the purpose is to distinguish active alveolitis from fibrosi.[1]


There are four stages of pulmonary involvement based on radiological stage of the disease, which is helpful in prognosis:[2]

  • Stage I: bilateral hilar lymphadenopathy (BHL) alone
  • Stage II: BHL with pulmonary infiltrates
  • Stage III: pulmonary infiltrates without BHL
  • Stage IV: fibrosis.
