Question 1

Using the hip localization method,the femoral head can be located:

D)  at the level of the symphysis pubis.

Question 2

A radiograph of an axiolateral (inferosuperior)projection of the hip reveals a soft tissue artifact seen across the affected hip.This artifact prevents a clear view of the femoral head and neck.What must the technologist do to eliminate this artifact or its effect during the repeat exposure?

Accepted Answer

A)  Increase the kV. 
B)  Ensure that the CR is centered to the grid to prevent grid cutoff. 
C)  Increase the elevation and flexion of the patient's unaffected leg. 
D)  Slightly rotate the patient toward the affected side and angle 5° caudad.

Question 3

A radiograph of an axiolateral (inferosuperior)projection reveals that there is an excessive amount of grid lines present.A 6:1 linear grid was used.Which of the following points will correct this problem on the repeat exposure?

Accepted Answer

A)  Use a screen rather than a grid. 
B)  Decrease the SID. 
C)  Keep the image receptor parallel to the femoral neck and perpendicular to CR. 
D)  Keep the image receptor perpendicular to the femoral neck.

Question 4

Gonadal shielding of the male patient for the AP pelvis projection requires that the top of the shield is not extend above the level of the:

Accepted Answer

A)  ASIS. 
B)  ischial spine. 
C)  inferior margin of the symphysis pubis. 
D)  none of the above; gonadal shielding cannot be used due to possible covering of pertinent anatomy.
