Points to remember...
• PROJECTION: • Supine AP– Tube to film distance = 3feet– Heart size and mediastinal width will be
exaggerated by both the supine position and the AP projection
• PA view– 2 years and above

Points to remember...
• PHASE OF RESPIRATION
Inspiration: Diaphragms 5th – 7th anterior rib
Expiration: will exaggerate the heart size and bronchovascular
markings

Points to remember...
• SYMMETRY: – check the symmetry of the ribs and the distance of
the medial borders of the clavicles from the spinous process of the vertebrae
• AGE: variability– Normal Anatomy corresponding to age

ABC
• A – Abdomen– Bowel gas pattern suggesting ileus or obstruction,
free air, abnormal calcification, abdominal situs.• B – Bone– Fractures, lytic or blastic lesions, metabolic bone
diseases.• C – Chest– Midline trachea and mediastinum, abnormal
mediastinal and cardiac contours, position of the aortic arch and pulamonary pathologies

Newborn
• Globular configuration of the heart– Prominent RV rounding of the apex– Thickening of the tunica and increase pulmonary resistance
physiologic pulmonary HPN • Hyperaerated lung (Radiolucent)
– Thin chest wall– Smaller pulmonary vessels and hilar structures
• Air Bronchogram– NORMAL: trachea, R&L mainstem bronchi and 2° airways– PATHOLOGIC: Hyaline membrane disease and Consolidation

Newborn
• THYMUS GLAND “Sail’s Line”
Normal
Same density with the heart
Trachea and esophagus not
distorted
Regresses by 2 years old
