Flashcards in Radiographic case studies Deck (9):
1

3 causes of poor quality radiograph

- poor position
- incorrect exposure
- faults

2

How many radiographs do you need to take?

- minimum 2 projections
- contralateral limb may be useful
- repeat after a period of time (since many radiographic abnormalities are non-specific)

3

Why might you report a normal appearance as abnormal? 2

- film fault
- unfamiliar with anatomical variations

4

What are radiographic signs of chronic nephritis?

- reduced size
- abnormal shape
- increased opacity

5

What are 4 radiographic signs of disc prolapse?

- narrowed IVD space
- calcified material superimposed on vertebral canal
- small and/or opaque intervertebral foramen
- gas in intervertebral space ('vacuum phenomenon')

6

T/F: whether a radiograph is taken VD or VD, the right limb always appears on the LHS of the image as your look at it

True - this is a convention adapted from human medicine

7

Would you expect to see abdominal structures on a radiograph of a young animal?

No - you often don't see abdominal structures clearly as they lack the abdominal fat needed for contrast. Thus you wouldn't expect to see the bladder in any young animal.

8

What are the 4 possible locations for a thoracic lesion?

- lung
- mediastinum (remember this is a little to the LHS)
- pleura
- thoracic walls (includes spine, ribs etc)

9

If there was a mass in the mediastinum where would it push the heart?

push the heart caudally, v unlikely to push it left or right.
