Overview
CT
A CT scan may be used to confirm the diagnosis.
HRCT
On HRCT, airspace consolidation with air bronchograms is present in more than 90% of patients, often with a lower zone predominance. A subpleural or peribronchiolar distribution is noted in up to 50% of patients. Ground glass or hazy opacities associated with the consolidation are detected in most patients. Pulmonary physiology is restrictive with a reduced DLCO. Airflow limitation is uncommon; gas exchange is usually abnormal and mild hypoxemia is common.
