1

T/F: Pneumomediastinum may result in dyspnea

False

1

If you see an enlargement in this region, what should your top two differentials be? 

Tracheobronchial lymphadenopathy and Left atrial enlargement

2

T/F: Ring Shadows (donuts) are often associated with a bronchial pattern

True

Bronchial pattern: donuts and tram lines

3

T/F: Hepatic veins have a hyperechoic wall on ultrasound

False

Hepatic veins have an isoechoic wall

3

This is a sagittal image of the left kidney. Which side is cranial?

That one.

3

What view would be best for evaluating lesions in the right lung lobes?

Left Lateral

In small animals, lung lesions generally are detected best in the non-dependent lung because the "up" lung is better aerated and therefore provides better contrast of lesions

Keep in mind, other lesions (not in the lung) generally are best seen on the "down" side because they are not distorted by magnification

3

What echocardiographic modality would you use to measure wall thickness during systole and diastole? 

M Mode

4

Name the MR sequence that nulls signal from free fluid (i.e. CSF):

FLAIR

FLuid Attenuated Inversion Recovery

4

Is sternal lymphadenopathy present in this patient?

Yes.

Note the enlargement of the sternal lymph node

4

T/F: Ascites is commonly associated with mitral valve insufficiency

False

That is false

5

Is the circled lesion more likely in the lung or the mediastinum?

Lung

Note the acute angle to the body wall. If the lesion was in the lung you would not have such an acute angle

5

With which radiographic view is mediastinal shift best visualized?

VD/DV

5

Doppler measurements should be taken with the patient in ______ lateral recumbency

LEFT

5

If you see a "bow-legged cowboy sign" on a DV view, what is your DDx?

left atrial enlargement

6

Identify the lymphatic structure indicated by the number 3:

Tracheobronchial

6

T/F: Diaphragmatic hernias cause caudal displacement of the gastric axis

False

Diaphragmatic hernias cause cranial displacement of the gastric axis

7

Long-axis left ventricular outflow view. 

Identify the structure indicated by the number 2

right atrium

8

T/F: An overexposed radiograph is too light

False

An overexposed radiograph is too dark. Either kVp or mAs is too high.

8

T/F: If you suspect a lesion in the right lung of a dog, a left lateral thoracic radiograph should be made

True

8

What diagnostic imaging modalities might you use if you suspect a diaphragmatic hernia?

Radiographs, Ultrasound, Barium Study

RUB the hernia...

 

 

 

...creep

9

T/F: Atelectasis is associated with normal to increased size of the lung lobe

False

Atelectasis is associated with decreased size of the lung lobe

Consolidation is associated with normal to increased size of the lung lobe

11

This presentation is most often associated with _______ insufficiency

 

mitral insufficiency

Turbulent flow (regurgitation); often bright and a mixture of colors

11

T/F: Mammary adenocarcinomas are typically associated with mediastinal lymphadenopathy

False

12

T/F: Tracheobronchial lymphadenopathy is an example of a cranioventral disease

False

Tracheobronchial lymphadenopathy is an example of a dorsal disease

12

T/F: Pneumothorax may progress to pneumomediastinum

No!

Pneumomediastinum may progress to pneumothorax, but not the other way around

13

When using grids for radiographs, how should you adjust the mAs?

Increase mAs

The grid 'intercepts' scatter from patient before it reaches film. You need 2x-3x more photons when grid is used (higher mAs) due to absorption of primary beam by lead

13

If you suspect a right lung lesion, what radiographic views would you take for the dog? What about a horse?

Dog: R → L

Horse: L → R

14

Which has better contrast resolution: flat panel or film?

Flat panel

14

Identify the cardiac abnormality:

Pericardial Effusion

14

T/F: The cranial vena cava is normally visible radiographically in the mediastinum

False
