Answer 2

fluid or free air

Question 3

how are the forelimbs positioned for a lateral view of the abdomen

Answer 3

pulled cranially

Question 4

Answer 6

Right and left lateral views and a VD or DV

Question 7

Which lung field is best visualized in an animal that is laying in left lateral recumbency?

Answer 7

Right lung field (opposite side that is on the table because it can inflate and isn’t compressed)

Question 8

high kVp produces a _____ scale of contrast

Answer 8

long

Question 9

where is the beam centered for lateral thoracic radiographs

Answer 9

between the 5th and 6th rib, over the heart

Question 10

where do you measure for lateral thoracic radiographs

Answer 10

over the caudal border of the scapula or the highest/thickest point

Question 11

why do you want to position the forelimbs cranially for a lateral thoracic radiograph

Answer 11

You don’t want the limbs to superimpose (overlap and cover up) the thorax.

Question 12

density is controlled by

Answer 12

mAs

Question 13

contrast is controlled by

Answer 13

kVp

Question 14

A thoracic radiograph image is made at 12 mAs and 68 kVp. It is now necessary to halve the radiographic density. Which technique do you now use?

Answer 14

6 mAs and 68 kVp

Question 15

which view is best for evaluation of the heart and why

Answer 15

DV because heart is in it’s normal position, close to the sternum.

Question 16

which view is best for evaluation of the lungs

Answer 16

VD at peak inspiration

Question 17

what does dependent lung mean

Answer 17

The lung that is on the table side of the patient, the downward lung.

Question 18

the dpendent lung can’t fully inflate because of ______ and the lung is being compressed by the ______

Answer 18

gravity
heart

Question 19

What is the medical term for collapsed alveoli?

Answer 19

Atelectasis

Question 20

how soon can atelectasis occur in lateral recumbency

Answer 20

in less than 5 mins

Question 21

A tech should measure where for a thoracic radiograph?

Answer 21

At the caudal border of the scapula or over the thickest part of the thorax.

Question 22

The cranial border for a lateral thorax is located where?

Answer 22

At the cranial point of the scapulohumeral articulation, where the scapula and humorous join.

Question 23

For the lateral thorax, make sure to include the _____ _____ to get the full ________

Answer 23

thoracic inlet
ribcage

Question 24

The caudal border for a DV thorax view is

Answer 24

a few centimeters caudal to the last rib.
