2. Skeletal Anatomy Review: Skull

3. Small Animal Skull: Radiographic Concerns
Proper imaging can be challenging:
Complicated anatomy
Superimposition of many structures
Symmetry is essential
Variations among breeds

4. Small Animal Skull: Radiographic Concerns
Indications for skull imaging:
Trauma
Congenital abnormalities
Inflammatory lesions
Tumors
Degenerative changes
Sedation or anesthesia usually required
Extra problem?
Tongue and pinnae can superimpose important anatomy

5. Skull: Primary Views DV VD
Lateral

6. Skull: Lateral View Tips & techniques:
Mandible should be parallel to long side of cassette
Tape can be used for positioning – Keep out of area of interest
Pads can be placed under the nose & neck to minimize rotation
Ensure pinnae are not superimposed

7. Skull: Dorsoventral View

8. DV

9. Skull: Ventrodorsal View
Tips & techniques:
For evaluation of the nasal passages and sinuses are located dorsally
Make sure hard palate/nose are parallel to table
True symmetry is achieved if there appears to be only one structure on radiograph

11. Radiographing the skull…
There are many alternate views that can be taken, depending on the area of interest and equipment available
