Figure 1. Coronal and axial chest views of a [18F] FDG positron emission tomography/computed tomography (18F-FDG PET/CT) examination, using [18F] FDG and a low-osmolar radiocontrast agent iohexol. This examination was performed 72 min before the initial episode of hemoptysis and reveals bilateral upper lobes ground-glass opacities with low tracer uptake, suggestive of diffuse alveolar hemorrhage.
