Fig 2. Breakdown of computed tomographic (CT) scoring for patients who underwent open thoracotomy (grey bars) and those who underwent thoracoscopic surgery (black bars). Data from 84 patients who had CT scans within 3 days of surgery were analyzed to determine whether the CT findings could predict the surgery that would be necessary to effect drainage. Readings of frank radiologic empyema indicated that patients were more likely to require open rather than thoracoscopic drainage.
