Clavicle

Question 1

CR: Perpendicular to the midshaft of the Clavicle.
POSITION:
-Place the patient in the
supine or upright
position.
- Center the clavicle to the IR.
SS: This projection demonstrates a
frontal image of the clavicle.

Answer 1

AP PROJECTION

Question 2

is most useful when
improved recorded detail is desired. The
advantage of the PA projection is that the clavicle is closer to the image receptor.

Answer 2

PA PROJECTION

Question 3

CR:
- Directed to enter the midshaft of the
clavicle.
- For the standing lordotic position, 0 to
15 degrees is recommended.
- For the supine position, 15 to 30
degrees is recommended.
POSITION:
- Lean backward in a
position of extreme
lordosis, and rest the
neck and shoulder
against the vertical grid
device. The neck will be
in extreme flexion.
- Center the clavicle to
the center of the IR.
STRUCTURE SHOWN: An axial image of the clavicle is projected above the ribs.

Answer 3

AP AXIAL PROJECTION
(Lordotic position)

Question 4

CR: Perpendicular to the plane of the IR at an angle of
25 to 40 degrees so that the central ray will pass
between the clavicle and the chest wall.
POSITION:
- Depress the shoulder to place the clavicle in a
horizontal plane
- Have the patient turn the head away from the side
being examined.
- Place the IR on edge at the top of the shoulder
STRUCTURE SHOWN: An inferosuperior image of the clavicle is demonstrated, projected free of
superimposition.

Answer 4

TANGENTIAL PROJECTION

Question 5

CR: Directed anterior and inferior to the midshaft of the clavicle at a 25 to 35 degree angle.
POSITION:
- Center the IR to the
projected clavicle area,
and have the patient
hold the IR in position.
-Lean slightly forward.
STRUCTURE SHOWN: The clavicle above the thoracic cage is demonstrated.

Answer 5

TARRANT METHOD (under tangential
projection)
