  2. Respiration Imaging Quiz Canine START!

  3. Choose a region… • I want to x-ray the: • Head • Larynx and Hyoid Apparatus • Trachea and Bronchi

  4. The Head • Do you want a: • Lateral view • Dorso-ventral view

  5. The Head - Lateral • What is A? • Nasopharynx • Maxillary Sinus • Frontal Sinus • What is B? • Soft Palate • Hard Palate • Nasal Septum • What is C? • Dorsal conchae • Ethmoidal conchae • Vomer A C B

  6.  Correct!  • Yes! This is the Frontal Sinus! • Here are some more examples. • Try part B

  7.  Incorrect • No, this is not the nasopharynx! • Here is the Nasopharynx: • Try again!

  8.  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!

  9.  Correct!  • Yes! This is the Hard Palate! • Here are some more examples. • Try part C

  10.  Incorrect  • No, this is not the Soft Palate! • Here is the Soft Palate: • Try again!

  11.  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!

  12.  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

  13.  Incorrect  • No, this is not the Ethmoidal Conchae! • Here are the Ethmoidal Conchae: • Try again!

  14.  Incorrect  • No, this is not the Vomer! • Here is the Vomer: • It is not easily distinguished from the hard palate on radiographs. • Try again!

  15. The Head – D/V • What is A? • Hard Palate • Vomer • Ventral Conchae • What is B? • Maxillary Sinus • Nares • Palatine Fissure • What is C? • Dorsal Conchae • Nasal Septum • Philtrum C B A

  16.  Correct  • Yes! This is the Vomer! • Here are some more examples. • Try part B

  17.  Incorrect  • No, this is not the Hard Palate! • This is the Hard Palate: • Try again!

  18.  Incorrect  • No, this is not the Ventral Conchae! • Ventral Conchae are not visible on dorso-ventral radiographs. • Try again!

  19.  Correct  • Yes! This is the Palatine Fissure! • Here are some more examples. • Try part C

  20.  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!

  21.  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!

  22.  Correct  • Yes! This is the Nasal Septum! • Here are some more examples. • Do you want to • See lateral head images • Pick a new region

  23.  Incorrect  • No, this is not the Dorsal Conchae! • The Dorsal Conchae are internal structures: • Try again!

  24.  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!

  25. Larynx & Hyoids Question 1

  26. 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 1. A E B D C

  27.  Incorrect Try Again!

  28.  Correct • Well done! Here are some more examples of the Hyoid Bones: S E C B T Now try Question 2

  29. What structures are shown in the circled area on this radiograph? • The Laryngeal Cartilages • The Hyoid Bones • The Tympanic Bullae 2.

  30.  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.

  31.  Incorrect These are not the Hyoid Bones. They appear as thin, linear bones. See Question 1 for views of the Hyoid bones. Try Again!

  32.  Incorrect Try Again! 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:

  33. Trachea and Bronchi Do you want: Normal Views Contrast Views

  34. 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 Gas shows up as black on radiographs They are obscured by the heart. A • What is structure A? • The Oesophagus • The Cranial Vena Cava • The Trachea Back to Trachea and Bronchi

  35.  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

  36.  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!

  37.  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!

  38.  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!

  39.  Incorrect  No! This is not the Cranial Vena Cava. This structure is black, suggesting it is gas-filled. Try Again!

  40.  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:

  41. Contrast View of Lungs (Feline) • Which is the Trachea: A, B or C? • Which is the Bronchi: A, B, or C? • Which is the Bronchioles and Alveoli? A, B, or C? Back to Trachea and Bronchi A C B

  42.  Correct  Well done! This is the Trachea! Here are other examples: Oesophagus Try part B

  43.  Correct  Well done! These are the Bronchi! Here is another example: Try part C

  44.  Correct  Well done! These are the Bronchioles and Alveoli! Here are other examples: Back to Contrast Lung ViewBack to choose a region

  45.  Incorrect Try Again!
