the heart borders should be clearly visible, the right border should be seen to the right of the spine.
cardio-thoracic ratio should not be greater than 50%.
Normal lungs and lung markings
- Pulmonary vessels and fissures appear as lines markings or shadow across the lung fields
- Bronchi are normally only visible near the hilae
- bronchus should only be 1mm or less in thickness.
