Chest x ray interpretation
The document provides a detailed overview of chest X-ray interpretation, outlining the essential steps for proper analysis, including labeling, positioning, and exposure considerations. It discusses normal and abnormal findings, identifying key structures such as the heart, lungs, and pleura, while also describing various pathological conditions and their associated radiological features. Key abnormalities in chest X-rays are classified by patterns of radiopacity and radiotranslucency, with potential causes listed for each type.

- 19. Pleura Thereare two layers of pleura: the parietal pleura and the visceral pleura. The parietal pleura lines the thoracic cage and the visceral pleura surrounds the lung.
- 21. Diaphragm Contour Rounded with sharp pointed costophrenic and costocardiac angles. Blunting of costalphrenic or costocardiac angles suggests plueral effusion. Right diaphragm is usually 1-2 cm higher
- 25. Abnormal Chest X-ray Radiopacity (whiteness) means increased density Radiotranslucency (blackness) means decreased density Radiopacity can be of 3 causes Alveolar pattern – fluffy, soft, poorly demarcated opacifications < 1 cm in diameter Possible causes: Pulmonary edema Viral pneumonia Pneumocystis Alveolar cell carcinoma

- 27. Abnormal Chest X-ray Interstitial pattern Consolidation of interstitial tissue (alveolar walls, intralobular vessels, interlobar septa and connective tissue) Looks like branching lines radiating toward the periphery of the lung Possible causes: Interstitial pneumonitis Pulmonary fibrosis

- 29. Abnormal Chest X-ray Vascular pattern – assessment of the pulmonary arteries and capillaries If there is an increase in the size of the pulmonary arteries as they extend out into the lung – pulmonary hypertension If there is a decrease in size, truncation, or obliteration of a pulmonary artery – embolus Lack of vascular making in the periphery - pneumothorax
