2. Radiology Flashcards
Name 3 intra oral radiographs:
Bitewings
Periapicals
Occlusal
What are the two types of bitewings?
Horizontal and vertical
What colour is the bitewings holder?
Red
Where does the orientation dot go when taking bitewings?
Bitewings: dot to palate
PA: dot to crown
What are the 2 types of PA radiograph?
Posterior and anterior
What colour is the PA holder?
Posterior - yellow
Anterior - blue
Where does the orientation dot go when taking a PA?
Dot to crown
What are the two types of occlusal radiographs?
Mandibular
Maxillary
Name the 6 E/O radiographs:
DPT
Lateral ceohaologram
Posterior- anterior mandible
Reverse Townes
Lateral oblique mandible
Occipitomental
Name 4 other imaging modalities:
CBCT
MRI
ULTRASOUND
NUCLEAR MEDICINE
What is the bisected angle technique?
Where the X-ray tube bisects the angle of the film at 90 degrees.
What is the parallax rule?
Where two views of the same object are taken with a change in the beam angulation.
Rule: PAL
- palatal always moves with the tube
