Computed tomography is essential for diagnosing and monitoring lung sarcoidosis, providing comprehensive information on both pulmonary and mediastinal involvement. Identifying specific HRCT phenotypes allows for accurate classification into non-fibrotic and fibrotic forms, which helps predict disease prognosis and guide clinical management.

Radiologists' familiarity with these phenotypic patterns is critical for delivering precise and actionable information to the multidisciplinary team, improving patient outcomes.

In the era of HRCT, chest X-ray should only be used when the former is unavailable, as HRCT offers a more detailed and accurate assessment of sarcoidosis. This shift necessitates updating current guidelines and creating new classification systems to incorporate the enhanced diagnostic capabilities provided by HRCT.
