Oral and Maxillofacial Radiology Flashcards
1
Q
when is radiology input required for cancer care?
A
- diagnosis
- staging
- pre-radiotherapy
- tx response
- recurrence
- post-op complications
- dental rehabilitation
2
Q
in an OPT, what sort of things may we come across?
A
- moth eaten bone
- pathological fractures
- non-healing sockets
- floating teeth
- spiking root resorption
- unusual perio bone loss
- generalised PDL widening & loss of lamina dura
- loss of bony outlines
3
Q
in an ultrasound what are we looking for?
A
- rounded lymph nodes
- enlarged lymph nodes
- necrosis of nodes
- increased vascularity or avascular
- loss of hilum
4
Q
what is TNM staging and its use?
A
used to stage cancer
T = tumour
N = nodes
M = metastasis
- imaging with a large FoV allows us to see distant metastasis (CT/MRI)
5
Q
what imaging is the best for staging cancer?
A
6
Q
what is the use of PET? (Positive emission tomography)
A
if you’re unable to see primary tumours,
PET allows for visualisation of metabolically active tissues
7
Q
when radiographically assessing tx response, what do we look for?
A
- looking for reduction in size of tumour
8
Q
what are some post-tx complications with cancer tx?
A
- infection
- osteoradionecrosis
