Planning
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]
Evaluation
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.
