Computed tomography scans were performed on a clinical 64-detector CT scanner, mostly in the portal venous phase (80% portal venous, 12% native, and 8% arterial). The data were reconstructed in the transverse plane with a slice thickness of 1 mm and an increment of 1 mm. Volumetry was performed by an experienced radiologist (J. S.) using a dedicated DICOM Viewer (Centricity Universal Viewer Version 6.0, GE Healthcare, Munich). Volumetric measurements of pleural empyema were calculated using the DICOM viewer in a semiautomatic fashion, where borders were marked manually in the transverse plane on each slice (Fig. Pre- and post-treatment CT-volumetry of the empyema cavity.
