DMSU 241 MODULE 3 EXAM QUESTIONS
AND ANSWERS ALL CORRECT
Which of the following statements represents findings that are likely associated with
fibromuscular dysplasia? - Answer- Sudden turbulence and high velocities in the distal
ICA
A true lumen and the false lumen of a vessel with a dissection can display which of the
following flow profiles except - Answer- Normal flow patterns in both lumens
Where is the carotid body located? - Answer- Within adventitial portion of the vessel
walls at the carotid bifurcation
Low velocity flow in the left or right carotid system when significant disease is not
present can be caused by - Answer- Both A and B
A patient presents which a 2-CM homogenous mass between the internal and external
carotid arteries. Color imaging of this mass reveals both arterial and venous signals
within a network of small vessels. Which is the most likely cause of these symptoms? -
Answer- Carotid Body tumor
Some dissections may be associated with all of the following additional complication
except - Answer- an arteritis
What are the most common presenting symptoms of patients with fibromuscular
dysplasia? - Answer- Asymptomatic or bruit
If the peak systolic velocity is 200 cm/sec, the diastolic peak is 80 cm/sec, and the
spectral broadening is present, the approximate stenosis is - Answer- 50 to 70%
Which group below has the highest incidence of fibromuscular dysplasia - Answer-
Female, Caucasians, 20-50 years old
When attempting to confirm the present of fibromuscular dysplasia, which one of the
procedure/techniques would be least helpful? - Answer- Turn off harmonic imaging and
use fundamental imaging
Which of the following statements is NOT true regarding the carotid arteries? - Answer-
The ECA has no branches before entering the cranium.
