Thorax Flashcards
Identify this structure:
trachea
Identify the structure that the orange line is going through.
trachea
Identify this structure:
bifurcation of the trachea
Identify this structure:
trachea
Where is the tracheal bifurcation located?
1/3 down from the dorsal lung to the cardiac apex
Is a right bend in the trachea normal?
Yes, it is commonly seen in bullies, beagles, and shit tzus
In what view is it easiest to see the cranial vena cava?
in the ventrodorsal view
In what view is it easiest to see the caudal lobar pulmonary vessels?
dorsoventral
What is in the heart?
the pacemaker
Where is the pulmonary mass located?
left caudal lung lobe
What is this?
pneumothorax
What is located here?
right atrium
Identify this structure:
right ventricle
Identify this structure:
left atrium
Identify this structure:
left ventricle
Where does the left atrium sit in lateral views?
just ventral to the mainstem bronchi
Where are veins usually located in a lateral radiograph?
ventral
Where are veins usually located in a DV or VD radiograph?
central
Where does the left atrium sit in DV or VDs?
between the mainstem bronchi to the caudal lung lobes
What is this?
fat halo
Identify this structure:
aorta
Identify this structure:
thymus
Identify this structure:
thymus
Identify this structure:
right atrium
Identify this structure:
pulmonary artery
Identify this structure:
left atrium
Identify this structure:
aorta
Identify this structure:
left ventricle
Identify this structure:
aorta
What is identified by the purple line?
caudal vena cava
Identify this structure:
cat esophagus
Which lung lobes wrap around the midline
both right and left cranial lung lobes
The tip of what lung lobe wraps across the midline and what species is it common in?
left cranial lung lobe tip in the dog more than the cat
What is positional atelectasis?
The idea that the amount of air in the lungs helps to determine the opacity or attenuation of the lungs as seen on x-ray or CT
What is transient positional atelectasis?
it occurs when the dog is in dorsal recumbancy, the dorsal aspect of the lung is not filled but can be fixed if the dog is put in a different position
Generally, where will a dogs heart be if it is deep chested?
the heart silhouette will be more vertical/upright on the lateral view; cardiac width in the lateral view is 2.5-3.5
About how many intercostal spaces is between the apex of the heart and the diaphragm in the cat?
one
How does the cardiac silhouette of the cat compare to the dog?
generally it is more narrow and takes up 1/3 of the thorax
How do you measure the vertebral heart score?
count the vertebrae back from T4 to measure both the length from bifurcation of the trachea down to the apex of the heart, perpendicular width at the atria and ventricle interface; add the lengths to get your score
Where is the thymus generally located in radiographs?
located in the cranioventral mediastinum adjacent to the pericardial sac
At the 9th rib, what is the size of the pulmonary vessels?
no larger than the 9th rib
In a right lateral view, where is the caudal vena cava seen?
directly in the center
In the left lateral view, where can the fundus be seen?
dorsal to the caudal vena cava
