1

How to collimating beam for thoracic radiograph

Thoracic inlet to caudal lung tips (last rib)
Thoracic spine to sternum

2

Inspiration

Caudal lung tips extend to T12
Diaphragm further from cardiac silhouette
Lungs have appropriate opacity

3

Expiration

Caudal lung tips cranial T12
Diaphragm closer to cardiac silhouette
Lungs have increased soft tissue capacity

4

Right lateral

Diaphragm crura parallel
Right crus cranial to left
CVC inserts into right
Heart is more oval

5

Left lateral

Diaphragm crura diverge dorsal lay
Left crus cranial to right
CVC inserts into right
Heart is more round

6

Landmarks for VD or DV

Sternum straight
-lined up with spine
Collimating
- thoracic inlet to last rib
Peak inspiration
-maximized contrast

7

DV

Critical animals
Better visualization of caudal pulmonary vasculature

8

VD

Easier to get straight
Better visualization accessory long lobe and great vessels

9

VD projection

Diaphragm crura have 3 humps
Cardiac silhouette is more oval

10

DV projection

Diaphragm is one smooth curve
Cardiac silhouette is more round

11

Evaluation for pneumothorax

Doral recumbency horizontal beam
Left or right lateral horizontal beam

12

Cranial mediastinal evaluation

VD
Patient erect - horizontal beam

13

What is in indicator of appropriate mA

If the peripheral areas of the film are black

14

Degree of tissue penetration if a guide for

Kilovolt peak (kVp)

15

Diaphragm anatomy

Tendinous center
Three thin peripheral muscles
- pars lumbar is
- pars costal is
- pars sternalis

16

Pars lumbalis

Right and left crura

17

Pars costalis

Oblique attachment to 8th - 13th ribs

18

Pars sternalis

Attachment to xiphoid cartilage

19

Diaphragm anatomy

Tendinous center
Three thin peripheral muscles
- pars lumbar is
- pars costal is
- pars sternalis

20

Pars lumbalis

Right and left crura

21

Pars costalis

Oblique attachment to 8th - 13th ribs

22

Pars sternalis

Attachment to xiphoid cartilage

23

Diaphragm anatomy

Tendinous center
Three thin peripheral muscles
- pars lumbar is
- pars costal is
- pars sternalis

24

Pars lumbalis

Right and left crura

25

Pars costalis

Oblique attachment to 8th - 13th ribs

26

Pars sternalis

Attachment to xiphoid cartilage

27

Normal anatomy - cats

Triangular thorax
Heart tilted cranially
-increases with age

28

Deep-chested dogs

Tall, thin hearts
Upright heart position
-little sternal contact
-may appear small

29

"Wolf - like" dogs

Round squat hearts
Wider than tall
-more sternal contact
Ovoid on VD

30

Chondrodystophy breeds

Wide and shallow
Short, round hears
Hearts appear "large"
-increased sternal contact
Barrel chested
Lots of mediastinal fat
