Radiography/Echocardiography Flashcards
What are the main way cat radiographs differ from the dog?
Feline thorax more triangular
Sternebrae rectangular
Heart more recumbent
Finer ribs
More lungs between cardiac silhouette and diaphragm
How to conduct a vertebral heart score:
- Measure long axis and short axis
- Align length w/ T4
- Count vertebrae from T4
- Add # vertebrae together
Normal: 9.7 +/- 0.5
How to estimate with a vertebral left atrial size (VLAS).
- draw line from carina to caudal LA border where caudal vena cava intersects
- Transpose that line up to start of T4
- Count vertebral bodies
>2.3 = enlarged
What does a bulge of the caudal cardiac waste/backpack sign indiacte?
Left atrial enlargement
Match these with actual rads/go through lecture
ok
What does a reverse āDā heart shape mean?
Right ventricular enlargement
What does a craniodorsal bulge of the cardiac silhouette indicate?
right aterial enlargement
What does a bulge at the cranial cardiac waist indicate? Often appears as widening of cranial mediastinum.
Aortic enlargement
What radiographic evidence shows left sided CHF?
Left atrial enlargement
Pulmonary venous congestion
Pulmonary edema
What radiogrpahic evidence shows right sided CHF?
Right atrial enlargement
Dilated vena cava
Cavitary effusion/pleural effusion obscuring the heart
What pattern do donuts and tramlines or sponges indicate?
Bronchial
What is bronchiectasis?
Pathologic dilation of the bronchi usually related to chronic inflammation and damage to the bronchial wall
What can a diagnosis be for distended chambers on echo?
Dilated Cardiomyopathy
What is the echo mushroom view?
The left ventricle on the right parasternal short axis view
What is the fish lips view?
mitral valve on the right parasternal short axis view
