Equine Diagnostic Imaging Flashcards
What is typically the first line of imaging in equine practice? What are 2 indications?
radiographs —> 2 views!
- lameness localized to a specific region
- boney abnormality suspected
What is view of the front limb is seen?
a. lateromedial
b. mediolateral
c. dorsopalmar
d. DMPLO
A
How is the horse positioned for radiographs? How are they done?
horse must stand squarely on the limb being radiographed
keep the plate medial or palmar/plantar —> some danger to the plate holder
Where are markers placed on the radiograph plate? When is it especially important to label hindlimb vs forelimb?
lateral or dorsal
if the hock or carpus is not in view —> fetlock
Which joint is the following radiograph diagnostic for?
a. coffin (DIP)
b. pastern (PIP)
c. fetlock (MCP)
B
Label the joints in the following radiograph.
top to bottom
- fetlock
- pastern
- coffin
Which of the 2 radiographs is considered good quality?
L —> straight joint space
- R has staggered condyles and oblique sesamoids, making assessment difficult
What view is seen in this radiograph?
a. DLPMO
b. DP
c. DMPLO
d. LM
D
Is this image diagnostic quality?
yes - straight joint spaces and superimposed bones
Which image is of diagnostic quality?
L
- R is more oblique - medial talus seen, splint bones are rotated
Orthogonal views of hindlimb:
What view is this?
LM
What view is this?
DP
What view is this?
DMPLO
- highlights DL and PM
What view is this?
DLPMO
- highlights DM and PL
What view is this?
DLPMO
- accessory carpal bone is highlights (lateral) and palmar
- L = offset splint bone
- DM + PL
What view is this?
DMPLO
- can’t see accessory carpal bone
- no L for the splint bone
What views are these?
- LM
- DP
