Imaging fibrosing alveolitis.

Whenever fibrosing alveolitis is suspected a computed tomographic (CT) scan should be carried out using a high definition narrow section technique. Pulmonary involvement in cryptogenic fibrosing alveolitis and scleroderma may be demonstrated by CT before it is apparent clinically or by standard radiography. CT may be the most accurate and practical imaging technique in the follow-up of these cases and for indicating the optimal site for biopsy.
