Summary
This review details common interstitial lung disease imaging features using high-resolution computed tomography (HRCT). It highlights HRCT findings for diseases like sarcoidosis and hypersensitivity pneumonitis, aiding diagnosis.
Area of Science:
- Pulmonology
- Radiology
- Medical Imaging
Background:
- Interstitial lung diseases (ILDs) encompass a heterogeneous group of disorders.
- Accurate diagnosis of ILDs is crucial for appropriate management.
- High-resolution computed tomography (HRCT) is the cornerstone of ILD imaging.
Purpose of the Study:
- To provide a comprehensive summary of typical HRCT imaging features of common ILDs.
- To correlate HRCT findings with established ILD classifications.
- To emphasize the secondary pulmonary lobule as the basic unit for HRCT description.
Main Methods:
- Review of typical imaging features of common ILDs.
- Emphasis on HRCT findings.
- Classification based on the American Thoracic Society consensus statement.
- Description of findings using the secondary pulmonary lobule as the anatomic unit.
Main Results:
- Detailed description of HRCT characteristics for various ILDs.
- Identification of key imaging patterns for differential diagnosis.
- Examples include sarcoidosis, Langerhans' cell histiocytosis, lymphangioleiomyomatosis, collagen vascular diseases, and hypersensitivity pneumonitis.
Conclusions:
- HRCT is essential for diagnosing and classifying ILDs.
- Understanding typical HRCT features aids in differentiating common ILDs.
- The secondary pulmonary lobule provides a standardized framework for HRCT interpretation in ILDs.
