Radiologic Evaluation

  • David A. Lynch


High resolution CT is useful for early detection and characterization of diffuse lung diseases. Optimal CT evaluation requires careful attention to technique. Radiologic diagnosis is based on the use of standard descriptive terms and the distribution of abnormality in the craniocaudal and axial planes. Confident CT diagnoses of several diffuse diseases, including usual interstitial pneumonia, sarcoidosis, hypersensitivity pneumonitis, smoking-related lung injury, Langerhans histiocytosis, lymphangioleiomyomatosis, based on typical CT findings and made in the appropriate clinical context, are usually correct. However, certain other radiologic findings, particularly ground-glass abnormality, consolidation and reticular abnormality, are relatively nonspecific and will usually require further diagnostic evaluation.
