| 2. What angle is required for a dorsopalmar/dorsoplantar oblique view of the third phalanx? |
|
Definition
| 45 degree angle to the ground and directed at the hoof wall |
|
|
Term
| 5. What are the splint bones also known as? |
|
Definition
|
|
Term
| 1. What x-ray tube is required for a dorsopalmar/dorsoplantar oblique view of the navicular bone with the animal standing on the cassette? |
|
Definition
Standing on cassette - Angled 65 degrees toward the middle of the second phalanx
On block w/ angled grooves – toe of hoof in vertical groove so dorsal hoof wall is vertical – beam directed parallel to ground and field of view should incl the 2nd/3rd phalanges |
|
|
Term
| 4. What view is taken to study the medial sesamoid bone of the right front fetlock? |
|
Definition
|
|
Term
| 1. Where should the beam be centered for views of the stifle joint?’ |
|
Definition
| Over stifle joint, approx. 4” distal to patella |
|
|
Term
1. How should lower leg films be correctly marked to distinguish
between each lower leg extremity of the horse? |
|
Definition
| Front/rear/right/left/medial/lateral |
|
|
Term
| T or F General anesthesia is not required to radiograph the equine pelvis |
|
Definition
|
|
Term
For normal to large equids, the patient must be under _________________
to perform pelvic radiographs due to the thickness and anatomical structure of the pelvic region. |

|
Term
| 1. What device can be used to protect the assistant during a lateral view of the distal phalanx? |
|
Definition
|
|
Term
| 1. What views are required when radiographing the thorax? |
|
Definition
Due to pt size, 4 views are usually req’d
- Craniodorsal lateral
- Caudodorsal lateral
- Cranioventral lateral
- Caudoventral lateral |
|
|
Term
| 1. What position should the horse be placed in when radiographing the shoulder joint? |
|
Definition
| Lateral recum under GA is ideal – not practical so can do a standing lateral view. Affected limb elevated and pulled cranially which pulls the shoulder joint away from the ventral body wall. Cassette placed firmly against the lateral aspect of the shoulder joint |
|
|
Term
| 14. Explain the skyline view for x-raying the carpus joint. |
|
Definition
Pt’s limb elevated, carpus joint flexed so metacarpus parallel to the floor. Cassette firmly against the dorsal surface of the proximal metacarpal region as nearly parallel to floor as possible. Beam directed toward the dorsal surface of the carpus. Angle of beam varies w/ desired row of carpal bones
Proximal row – beam directed at near-perpendicular angle
Distal row – beam angled approx. 3-0 degrees to the cassette |
|
|
Term
| Name two additional positioning devices used for x-raying the horse’s foot |
|
Definition
| positioning blocks and cassette tunnels |
|
|
Term
. How can you minimize distortion when radiographing the foot of a
large animal? |
|
Definition
| by proper placement of the foot on positioning blocks. Distortion occurs when the beam is not perpendicular to the cassette |
|
|
Term
Why is it important to mark the legs with proper identification on a
horse? |
|
Definition
| You cannot tell them apart on the film |
|
|
Term
. Why are lateral views of the horse’s pelvis only possible on small
equids? |
|
Definition
| because of the thickness of the area |
|
|
Term
| what should dorsopalamar and dorsoplantar projections technically be called? |
|
Definition
| They often incorporate a proximal to distal component, making them technically oblique views (dorsoproximal- palmarodistal and dorsoproximal- plantarodistal, respectively) |
