Lecture 5 Selected Equine Head Radiographic Anatomy Flashcards
1
Q
- what view is 1?
- 2?
A
- lateral
- dorsoventral
2
Q
3- what view?
- how do you take it?
4- what view?
A
3- maxillary oblique
- Take the x-ray beam from a true horizontal position, angle it 30% dorsal, and then angle it down through the maxillary of interest
4- mandibular oblique
3
Q
1?
2?
A
1- interdental space (diastema)
2- wolf tooth
4
Q
1?
2?
A
- Canine tooth
- Ovoid region in the bone
- Normal, not pathological
- Looking at end-on view of how the mandible wraps around, how the right and left halves join each other.
- We’re looking across that joining area, in this view.
5
Q
3?
what do you see in this area at 4?
A
3- Halter!
4- no points seen, has been floated recently
6
Q
which horse is older?
A
bottom right
- can see that the reserve crowns are shorter
7
Q
1?
2?
A
- Dorsal border of soft palate
- Ventral border of soft palate
8
Q
3?
4?
A
3- Knot of halter
4- Epiglottis
9
Q
5?
6?
A
5- hard palate
6- ethmoid turbinates
10
Q
7?
8?
A
7- Maxillary sinus
8- Frontal sinus
11
Q
- ?
- ?
- ?
A
- Medial border of mandible
- Mandibular teeth are medial
- Maxillary teeth are lateral
12
Q
4?
5?
A
4- Vomer bone
5- masseter muscle
13
Q
- Deciduous or adult teeth?
- Deciduous or adult teeth?
A
- Deciduous
- Permanent
14
Q
3?
4?
5?
A
3- Maxillary sinus
4- P2 (NOT P1)
5- M1
15
Q
1?
2?
3?
A
- Frontal sinus
- Conchal sinus
- Maxillary sinuses
16
Q
1?
A
Infraorbital canal
17
Q
What do you see here?
A
- soft-tissue/fluid opacity (most likely fluid)
- Follow the mitchell marker’s beads and draw a line
- any lines that are parallel to the beads will be fluid falling because of gravity
18
Q
what is seen here?
A
fluid at both lines
19
Q
what is seen here
A
- molar 1 is disease
- Decreased in opacity
- The shape of the root is blunted, rounded, compared to the others
- Opacity is half of what the others are
- High probability that the tooth abnormality is associated with the sinus abnormality
