3. Can be done erect or supine
The Views….. AP
AP Axial
Can be done erect or supine
Woo hoo! Not to many!!!

4. 40 SID The AP… Placement: Remove all metallic objects.
Place patient with back against the IR.
Patient looking straight so not to impose chin.
Center clavicle to center of IR.
Central Ray: Perpendicular to mid- clavicle
40 SID

6. The Ap… Contd
Seen on Radiograph:
The entire clavicle including both the ac joint and the sc joint.
The mid-clavicle will superimpose the superior scapula angle.
Medial clavicle will be next to the vertebral column.
Lateral end aligns with the acromion.

7. The AP axial view  Placement: Same as the AP. No movement of Patient.
Central Ray: Perpendicular to mid-clavicle
Angle Degrees cephalad.

8. The AP axial view..  contd.
Seen on Radiograph:
entire clavicle including both joints.
The medial end superimposes the first and second rib.
The lateral end is superior to acromion
No imposition of superior scapula angle
Clavicle bows slightly upward.
Most of the clavicle will be free of imposition.

9. the next view
scapula

10. General things you need to know about The scapula….
Cassette Size: 10 x 12 lengthwise
Shield: On Lap!
Put marker in light field.
Breathing technique for AP

11. Can be done erect or supine
The Views….. AP
lateral
Can be done erect or supine
Woo hoo! Not to many!!!

12. The AP… Placement: Remove all metallic objects.
Place patient with back against the IR.
Center scapula to center of IR.
IR should be 2 inches above shoulder and 2 inches medial form rib boarder.
Abduct arm 90 degrees.
Supinate the hand (moves scapula lateral to clear more thoracic structures)

14. Central Ray Perpendicular to the mid-scapula area
2 inches below the coracoid process or level of axilla and 2 inches medially.
40 SID

15. The Ap… Contd The entire scapula
Seen on Radiograph:
The entire scapula
The lateral portion of scapula free from imposition.
Medial portion will be seen through the thoracic structures.

16. The Lateral
10 x 12 lengthwise
Hold breathe
Measures 15

17. The Lateral
Placement: face patient toward cassette in and anterior oblique position with affected shoulder against the IR
Have patient reach across the chest and grab opposite shoulder. (body) less rotation
Have patient drop arm and place behind back ( acromion and coracoid)
Feel scapula and rotate scapula until a true lateral position is reached. About 30-45degree for scapula and for patient.

19. The lateral… Contd The entire scapula in a true lateral position
Seen on Radiograph:
The entire scapula in a true lateral position
The vertebral and lateral borders of body superimposed.
Body free of imposition by ribs and in profile
The scapula should form a Y.
The acromion and coracoid as the arms and the scapula body as the leg.
