1

How would you describe the arterial wall in this image?

Homogenous plaque with smooth surface characteristics

2

In this example, the ICA velocities may underestimate the category of stenosis. Why?

Sample was not obtained at maximum stenosis.

3

Is the flow direction in this right vertebral artery normal?

No

4

According to this image, what solution would provide a better spectral analysis display?

Increase the Doppler scale

5

Based on this image, what is needed in order to correct the velocity estimation and make it more accurate?

Decrease the angle

6

Based on this image, what should be used in order to detect flow in this ICA, if any?

 

Decrease color scale

7

According to this image, the Doppler velocity shown is estimated to be taken at:

 

The point of maximum stenosis

8

According to the information seen in this image, interpret the percentage of stenosis based on the 2003 SRU Consensus criteria.

 

>70% to near occlusion

9

If the vessel in this image were a carotid artery, what color would be shown in the proximal segment?

 

 red

10

If the vessel in this image was a tortuous ICA, what color would the most distal segment be shown as?

 

red

11

 This image represents which type of carotid pathology?

 

Ulceration as a source of emboli

12

Which vessel is labeled as 'B' in the diagram?

 

Right subclavian artery

13

Which vessel is labeled as 'C' in the diagram?

Right common carotid artery

14

Which vessel is labeled as 'D' in the diagram?

 

Right external carotid artery

15

Which vessel is labeled as 'E' in the diagram?

 

Right internal carotid artery

16

What 2 adjustments are needed in order to see color in this vessel?

 

rock the transducer to 'bank' the vessel and create an angle and steer the box to the right or the left

17

According to this image, blood in this carotid artery would show up as blue.

 

false, it would show up as red.

18

According to this image, blood in this carotid artery would show up as red

 

true

19

According to this image, color in the carotid would show up as red

False, it's not steered correctly, so no color would show up.

20

What are the arrows pointing to?

 

Temporal tap oscillations

21

What is this image showing in regards to the plaque seen in both views

 

This minor plaque can be made to look more or less stenotic in the longitudinal view.

22

True or False: The color display seen here in the bulb of the Internal Carotid Artery is indicating disease.

 

False

23

The velocity obtained in this doppler display is:

 

Overestimated

24

The velocity angle in this image is:

 

Underestimated

25

The Doppler waveform seen in this image is most likely the:

 

ICA

26

The Doppler waveform seen in this image is most likely the:

 

ECA

27

What best describes the vertebral waveform seen here?

a. early systolic deceleration

b. late diastolic deceleration

c. early diastolic acceleration

d. late diastolic acceleration

 

Early systolic deceleration

28

As you perform venous imaging on your next patient, you document this finding in the patient's popliteal fossa. The structure on the left of the image is LEAST likely to represent which of the following: hematoma, cyst, sarcoma, acute deep venous thrombosis or ruptured, Baker's cyst

 

acute deep venous thrombosis

29

What is wrong with this image?

 

Baseline is set to high

30

What is wrong with this image?

 

Inappropriate scale setting

31

Why does the image look this way?

 

Due to vessel stenosis

32

What does this image show in regards to flow?

 

Retrograde flow

33

What is the percentage of stenosis seen here?

 

<50% ICA stenosis

34

What type of flow is this waveform showing?

 

Phasic flow

35

What is wrong with the waveform shown here and how should you correct it?

 

It is above the baseline. Invert so that it is below baseline.

36

Does this show normalcy or venous reflux?

 

Venous reflux
