Flashcards in Radiographic case studies Deck (9):

3 causes of poor quality radiograph

- poor position
- incorrect exposure
- faults


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)


Why might you report a normal appearance as abnormal? 2

- film fault
- unfamiliar with anatomical variations


What are radiographic signs of chronic nephritis?

- reduced size
- abnormal shape
- increased opacity


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')


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


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.


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)


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.
