Page 5: Breathing Instructions
Normal Instructions: Patients should take a deep breath in and hold it during exposure.
Expiration Images: Occasionally, exposures may be taken during expiration to assess certain conditions like pneumothorax.
Page 6: Erect Chest Position
Recommendations: All chest radiographs should be performed in an upright position when possible.
Reasons:
Reduces distortion of anatomical structures.
Provides a more accurate representation of air-fluid levels.
Facilitates patient comfort and reduces the risk of complications.
Page 7: PA vs. AP Projections
Posteroanterior (PA) projections preferred over Anteroposterior (AP) to minimize heart magnification.
SID: Recommended to use 72 inches instead of 40 inches to further reduce enlargement of the heart.
