Acute pulmonary hemorrhage. CT evaluation.

The computed tomography (CT) scans and chest radiograph of seven patients with bronchoscopic or pathologically proven cases of pulmonary hemorrhage were reviewed to determine the appearance and value of each modality. CT revealed the presence and location in all cases while chest radiographs were falsely negative in two cases. The CT pattern was always an alveolar pattern while the pattern was more variable on chest radiographs. By providing better pattern definition than the chest radiographs, CT is the study of choice in detecting the presence of a suspected pulmonary hemorrhage.
