Compare Tissue Attenuation On x-rays because air is less dense and therefore shows up radiolucent (black), increasing amounts of soft tissue or less air shows up more radio-opaque or white. Similarly a “line” on an x-ray signifies air is present on both...
2. Evaluate for Pneumothorax – Sulcus Sign Left Image: Depicts the deep sulcus sign. Right Image: Lateral decubitis view of the pneumothorax. The pleural air will rise above the lung in this view.
3. Evaluate for Pneumothorax – Mediastinal Shift Large pleural effusions may cause a mass effect, shifting the mediastinum and trachea to the opposite side, and/or causing atelectasis of the adjacent lung. No image available
1. Evaulate for Pneumothorax – Lung/Air Contrast A pneumothorax allows visualization of the viscerla pleura as a curvilinear line, paralleling the chest wall, separating the partially collapsed lung from pleural air. Left Image: Pneumothorax on inspiration....
Identify: Parietal & Visceral Pleura The Pleura lubricates and prevents friction during respiration. The partial pleura lines the chest wall, mediastinal and diaphragmatic surfaces, while the visceral pleura lines the lungs and fissures.
