The document provides detailed instructions for performing a chest x-ray, emphasizing proper patient positioning and technical requirements for optimal image quality. Key points include centering the trachea, ensuring full inspiration, and visibility of specific anatomical features. Additionally, it outlines collimation margins and patient stance to achieve a clear view of lung fields.

1. CHEST X RAY
MAW MAW OO

8. Good quality
trachea is centered
equidistant from the head of the clavicle on both
sides
the spine is visible as a transparent structure
through the heart shadow,
full inspiratory effort
( the right 6th rib is at the midpoint of the
hemidiaphragm on that side)
Both Apices, costophrenic angles and the lower
parts of the diaphragm should be visible.

12. ROUTINE LEFT LATERAL

14. portrait (lengthwise) or landscape (crosswise)
upper collimation margin on the IR of about 1 -1.2
inches, or 4 cm, above the vertebra prominens
The level of T7 on an average adult is 3 to 4
inches (8 to 10 cm) below the jugular notch.

17. Patient erect, feet
spread slightly
Chin raised, resting
against IR
Hands on lower hips,
palms out, elbows
partially flex
• Shoulders rotated
forward against IR to
allow scapulae to move
laterally clear of lung
felds; shoulders
depressed downward to
move clavicles below the
apices
