High-resolution CT (HRCT) of the lung is a powerful tool for the investigation of patients with acute or chronic respiratory symptoms or diffuse parenchymal lung disease. Detailed knowledge of normal pulmonary anatomy and an understanding of how normal anatomy is altered in disease states are required to appreciate fully HRCT findings in patients with pulmonary disease. Detailed knowledge of the technical aspects of HRCT examinations is required for optimal image quality. With the proper foundation, a pattern approach to HRCT interpretation may then be used successfully to provide accurate and reproducible interpretation.
