5. Which of these statements is correct? 8. Why is collimation important for all views?
a. Using sedation for radiography is virtually never
required
b. Sedation will make fetlock radiography more
difficult to perform
c. Sedation will often help with the acquisition of
good quality radiographs in a shorter period of
time
d. Sedation is likely to increase the number of
repeated acquisitions required
e. Sedation never helps with acquisition of well
positioned radiographs a. To reduce scatter and optimise exposure factors
to achieve optimum image quality
b. To prevent unwanted anatomy included in the
radiographic image
c. To optimise radiation safety for personnel
performing radiography
d. All of the above
e. None of the above
6. Which of these radiographic views will offer the
best visualisation of the dorsal surfaces of the
proximal sesamoid bones?
a.
b.
c.
d.
e.
DP
Flexed DP
LM
Flexed LM
DPrM-PaDiLO
7. In what instance would a flexed DP be particularly
useful?
a. Further assessment of the proximal sesamoid
bones
b. Further assessment of the dorsal aspect of the
condyles of the third metacarpal bones
c. Further assessment of the sagittal ridge of the
third metacarpal bone
d. All of the above
e. None of the above
9. When placing a marker in an image where does
convention require the marker to be placed in
relation to the anatomy being imaged?
a.
b.
c.
d.
e.
Medially
Distally
Proximally and medially
Laterally
Proximally
10. What is the most important reason for the horse
to be stood standing squarely and weight bearing
evenly through the limbs when performing fetlock
radiography?
a. If the horse is sedated, it will always be unsteady
and may fall over
b. Uneven weight bearing is likely to result in
obliquity of the anatomy relative to x-ray beam in
the radiograph resulting in a less diagnostic image
c. When the horse is not standing squarely it is
difficult to get both limbs in the same radiograph
d. When the horse is standing unevenly it is difficult
to take a full set of radiographs of the joint
e. Uneven weight bearing will always result in motion
