Choose a region…
• I want to x-ray the:
– Head
– Larynx and Hyoid Apparatus
– Trachea and Bronchi
The Head
• Do you want a:
– Lateral view
– Dorso-ventral view
The Head - Lateral
• What is A?
– Nasopharynx
– Maxillary Sinus
– Frontal Sinus
A
• What is B?
– Soft Palate
– Hard Palate
– Nasal Septum
C
B
• What is C?
– Dorsal conchae
– Ethmoidal conchae
– Vomer
Correct!
• Yes! This is the
Frontal Sinus!
• Here are some more
examples.
• Try part B
Incorrect
• No, this is not the
nasopharynx!
• Here is the
Nasopharynx:
• Try again!
Incorrect
• No, this is not the Maxillary Sinus!
• The dog does not have a true Maxillary Sinus; it
has a Maxillary Recess which is not easily
visible on radiographs.
• Try again!
Correct!
• Yes! This is the Hard
Palate!
• Here are some more
examples.
• Try part C
Incorrect
• No, this is not the Soft
Palate!
• Here is the Soft
Palate:
• Try again!
Incorrect
• No, this is not the Nasal Septum!
• The Nasal Septum is cartilagenous and so is not clearly
visible on radiographs, except occasionally rostral to the
Maxilla:
• Try again!
Correct
• Yes! This is the
Dorsal Conchae!
• Here are some more
examples.
• Do you want to:
– See D/V head images
– Pick a new region
Incorrect
• No, this is not the
Ethmoidal Conchae!
• Here are the
Ethmoidal Conchae:
• Try again!
Incorrect
• No, this is not the
Vomer!
• Here is the Vomer:
• It is not easily
distinguished from the
hard palate on
radiographs.
• Try again!
The Head – D/V

Correct
• Yes! This is the
Vomer!
• Here are some more
examples.
• Try part B
Incorrect
• No, this is not the
Hard Palate!
• This is the Hard
Palate:
• Try again!
Incorrect
• No, this is not the Ventral Conchae!
• Ventral Conchae are not visible on dorsoventral radiographs.
• Try again!
Correct
• Yes! This is the
Palatine Fissure!
• Here are some more
examples.
• Try part C
Incorrect
• No, this is not the Maxillary Sinus!
• The dog does not have a true Maxillary
Sinus; it has a Maxillary Recess which is
not easily visible on radiographs.
• Try again!
Incorrect
• No, this is not the Nares!
• The Nares are soft tissue structures, they are not easily
visible on radiographs but are occasionally seen here:
• Try again!
Correct
• Yes! This is the Nasal
Septum!
• Here are some more
examples.
• Do you want to
– See lateral head images
– Pick a new region
Incorrect
• No, this is not the
Dorsal Conchae!
• The Dorsal Conchae
are internal
structures:
• Try again!
Incorrect
• No, this is not the Philtrum!
• The Philtrum is a fold of soft tissue
between the nares and upper lip; it is not
visible on radiographs.
• Try again!
Larynx & Hyoids
Question 1
1.
The hyoid bones have been labelled, which of the following is correct? A, B, C, D, E =
Ceratohyoid, Epihyoid, Stylohyoid, Basihyoid, Thyrohyoid
Stylohyoid, Epihyoid, Ceratohyoid, Basihyoid, Thyrohyoid
Thyrohyoid, Basihyoid, Ceratohyoid, Epihyoid, Stylohyoid
Stylohyoid, Epihyoid, Basihyoid, Ceratohyoid, Thyrohyoid

Correct
• Well done! Here are some more examples of the
Hyoid Bones:

Now try Question 2
T
2.
What structures are
shown in the circled
area on this
radiograph?
A.The Laryngeal
Cartilages
B.The Hyoid Bones
C.The Tympanic
Bullae
Correct
Yes! These are the Laryngeal Cartilages!
They are: Epiglottis, Thyroid, Arytenoid, Cricoid
As they are cartilagenous, they are not normally easy to see on
radiographs. The larynx is composed of these cartilages and soft
tissues which do not show up on x-rays, so is most easily located by
using the hyoid bones.
Back to Choose a region screen.
Incorrect
These are not the Hyoid Bones. They appear as thin, linear
bones. See Question 1 for views of the Hyoid bones.
Try Again!
Incorrect
These are not the Tympanic Bullae.
They are the bones of the skull
containing the middle ear space.
Here are examples of the Tympanic
Bullae:

Trachea and Bronchi
Do you want:
Normal Views
Contrast Views
Lateral Thorax
Although the lung field can
be distinguished on this
radiograph, the lungs
themselves cannot be seen
because:
1. The lungs are
abnormal/diseased
2.Gas shows up as black
on radiographs
3.They are obscured by the
heart.
A
What is structure A?
1.The Oesophagus
2.The Cranial Vena Cava
3.The Trachea
Back to Trachea and Bronchi
Correct
Yes! Gas does not absorb x-rays, so the film behind gas filled
structures such as the lungs is fully exposed and shows up as black.
Here are some other examples of normal lungs:
Back to Lateral Thorax
Back to Choose a Region
Incorrect
No! These lungs are normal. Abnormal lungs show up as pale white
and cloudy due to the presence of infected material or abnormal
tissue growth. Here are some examples:
Try Again!
Incorrect
No! The heart is the grey soft-tissue structure in the centre of the
thorax; although the lungs do wrap around the heart they extend far
beyond it.
Try Again!
Incorrect
No! This is not the Oesophagus! The oesophagus is not rigid and is
usually empty and collapsed on radiographs, making it hard to see.
Try Again!
Incorrect
No! This is not the Cranial Vena Cava. This structure is black,
suggesting it is gas-filled.
Try Again!
Correct
Yes! This is the Trachea! It is easily recognised as it is
gas filled and black. Further cranially it is sometimes
possible to identify the Tracheal Cartilages:
