Chest Image Search Pattern Feigin

David S. Feigin, M.D.


  • Verify patient information and date on both films and position of LEFT or RIGHT marker on frontal.
  • Note adequacy of penetration and any technical defects.
  • Look briefly at the entirety of both films for obvious abnormalities.



  1. Study the lungs, both up and down and side to side. Include lung volumes and symmetry of markings.
  2. Check periphery of lungs for pneumothorax and effusions.
  3. Evaluate mediastinal contours, edges and shape.
  4. Follow trachea to carina and main bronchi.
  5. Look at both hila for enlargement and abnormal bulges.
  6. Trace periphery of the chest – neck, chest wall, bones, diaphragms. Check the upper abdomen for free air and abnormal air collections



  1. Judge the size and shape of the lungs and diaphragms.
  2. Follow the airway from neck to hilum. Note shape of pulmonary arteries.
  3. Note back of heart and darkening toward diaphragm.
  4. Look upward for darkening of anterior mediastinum to the neck.
  5. Follow the spine downward for vertebral bodies and darkening.
  6. Trace periphery – forward through abdomen, up anterior chest wall and down posterior ribs to the costophrenic angles.
