SOLUTIONS
◉ 131. In duplex imaging, the best arterial wall quality is obtained
when the beam is at the following angle to the artery walls:
a) 90 deg
b) 60 deg
c) 0 deg
d) oblique
e) obtuse. Answer: a) 90 deg
◉ 132. TCD findings consistent with vasospasm following
subarachnoid hemorrhage would include:
a) absence of diastolic flow in the middle cerebral artery
b) greatly diminished diastolic flow in the middle cerebral artery
c) retrograde flow in the middle cerebral artery
d) greatly increased mean velocities in the middle cerebral artery
e) this is not a condition for which TCD is a useful modality. Answer:
d) greatly increased mean velocities in the middle cerebral artery
◉ 133. In TCD, the normal direction of flow in the vertebral artery is:
,a) toward the beam
b) away from the beam
c) bidirectional
d) dependent on the cardiac cycle
e) not detectable with TCD. Answer: b) away from the beam
◉ 134. Which of the following is NOT a condition for which TCD
might be useful?
a) vasospasm following subarachnoid hemorrhage
b) determination of brain death
c) cerebral artery monitoring during surgery
d) carotid siphon stenosis
e) temporal arteritis. Answer: e) temporal arteritis
◉ 137. In TCD, the normal direction of flow in the anterior cerebral
artery is:
a) toward the beam
b) away from the beam
c) bidirectional
d) dependent on the cardiac cycle
e) not detectable with TCD. Answer: b) away from the beam
, ◉ 138. A localized increase in mean velocity from 50 to 150 cm/sec
at a depth of 50 mm with the TCD transducer placed in the temporal
window probably indicates:
a) significant stenosis of the anterior cerebral artery
b) moderate generalized vasospasm
c) significant stenosis of the internal carotid at the siphon
d) significant vasospasm of the middle cerebral artery
e) significant stenosis of the middle cerebral artery. Answer: e)
significant stenosis of the middle cerebral artery
◉ 139. In a handheld TCD, the angle of the beam relative to flow is
assumed to be:
a) 0 deg
b) 30 deg
c) 45 deg exactly
d) 60 deg
e) 90 deg. Answer: a) 0 deg
◉ 140. You perform TCD, insonating the left anterior cerebral artery.
The flow is toward the beam. This finding suggests:
a) ipsilateral carotid obstruction, with right-to-left collateralization
b) contralateral carotid obstruction, with left-to-right
collateralization
