High-resolution CT: what is it good for in pulmonary fibrosis?

For many radiologists and clinicians, high-resolution CT has become a useful tool in the diagnosis of diffuse lung disease, particularly in the diagnosis of idiopathic pulmonary fibrosis. This paper reviews the most recent literature on the usefulness of high-resolution CT in diagnosing, determining the subsequent prognosis, and guiding the care of patients with lung disease. Idiopathic lung diseases, collagen vascular diseases, and the role of lung biopsy in diffuse lung disease are addressed.
