PA (Posterior to Anterior)
Lateral

3. Facts to Know for PA 14 x 17 Cassette
Crosswise for men
Lengthwise for women
Shielding required (around waist)
Mark in light field anatomically correct

4. Positioning of PA Patient is erect, weight evenly distributed
Mid-sagittal plane to mid-line of image receptor (IR)
Chin raised
Hands on lower hips
Shoulders rotated forward against IR
Shoulders depressed downward
NO ROTATION

5. Central Ray (CR) T-7 ( 7-8 inches below vertebral prominens)
Source to Image Distance (SID) 72 inches

6. Techniques
110 3 mAs
Collimate to outer skin borders laterally and top border should be level of vertebral prominens
Breathing- hold breath on 2nd full inspiration

7. Radiograph Critique Both lungs—apices and costophrengic angles
Air field trachea
Hilum markings
Rotations- sternoclavical (SC) joints equal distance from center of vertebral column
No scapula in lung field
No chin superimposition in apices
Correct KVP- vertebral bodies through heart shadow

8. Facts for the Lateral 14 x 17 cassette Shield Mark
Lengthwise for both men and women
Shield
Mark

9. Positioning for Lateral
Patient is erect
LEFT side against IR, weight evenly distributed
Align mid-sagittal plane parallel to IR
True lateral position
Arms raised above head
Chin elevated

10. Central Ray (CR)
CR is at mid- thorax at T-7 (3-4 inches below jugular notch)
SID 72 inches

11. Techniques
125 6 mAS
Collimation- lateral borders and top at vertebral prominens
Breathing—Suspend on 2nd full inspiration

12. Film Critique Entire lungs from apices to the costophrenic angles
Sternum anterior- ribs posterior
No superimposition of chin or arms in apices
No rotation- Ribs are superimposed
No tilting
Correct KVP- see rib outlines and lung markings through heart shadow and upper lung areas
