The Role of Thoracic Imaging in the Diagnosis of BOS and Related Disorders
Imaging plays a critical role in evaluating patients before and after lung transplantation. Chest radiography is usually the initial imaging test performed to evaluate transplant recipients with signs and symptoms of respiratory tract infection or acute graft dysfunction. However, the utility of chest radiography in patients with bronchiolitis obliterans syndrome (BOS) is very limited. Computerized tomography (CT) is more sensitive than radiography for lung abnormalities and may show findings of air trapping, consistent with the presence of constrictive bronchiolitis. This chapter reviews the current state of imaging of patients with documented or suspected BOS and illustrates the radiographic and CT findings.
