Question n°1
Which factors might influence the appearance of the cardiac silhouette?
Question n°2
Which is the least useful view for assessing cardiac shape?
-
Correct; with the VD view, the heart is flipped over backwards, losing some of the normal physiological cardiac shape.
Question n°3
Where is the left atrium?
-
Correct. The heart can be subdivided into different locations to evaluate cardiac abnormalities. 2 to 6 O'clock - left ventrucle, 6 - 10 O'clock - right ventrucle, 10 - 11 O'clock - right atrium, 11 - 1 O'clock - great vessels. These values are a useful guide but may vary between individuals and different breeds
Question n°4
Which vascular structure is marked by the arrows?
-
Correct. The size of the caudal vena cava can sometimes vary significantly throughout the respiratory and cardiac cycle. Its measurement must therefore be performed with caution
Question n°5
Which structures are marked by the arrows?
-
Correct. The arrow points to the artery, bronchus and vein from the right cranial lung lobe. The assessment of the pulmonary veins is easier with the left lateral and dorsoventral views.
Question n°6
Which vascular structures are marked by the arrows?
-
Correct. The artery is lateral and the vein is medial. The bronchus lies between the artery and vein forming a triad. Notice vessels form a summation shadow that is the shape of a square as they cross the ninth rib.
Question n°7
