Sample Questions and Answers

A patient presents with transient right-sided weakness lasting 15 minutes. Duplex ultrasound of the left internal carotid artery shows a peak systolic velocity (PSV) of 255 cm/s and end-diastolic velocity (EDV) of 110 cm/s. ICA/CCA ratio is 4.2. How should this stenosis be classified?

A. <50% stenosis
B. 50–69% stenosis
C. ≥70% stenosis
D. Near occlusion

Correct Answer: C

Explanation: According to validated velocity criteria widely used in vascular laboratories and aligned with consensus standards, an ICA PSV greater than 230 cm/s, EDV greater than 100 cm/s, and ICA/CCA ratio above 4.0 correspond to ≥70% diameter reduction. The patient’s PSV of 255 cm/s, EDV of 110 cm/s, and ratio of 4.2 clearly meet this threshold. Near occlusion would demonstrate markedly elevated velocities with distal collapse or reduced distal flow. Proper classification is critical because symptomatic patients with ≥70% stenosis may benefit from surgical or endovascular intervention.

During evaluation of suspected subclavian steal, retrograde flow is identified in the vertebral artery. Which waveform pattern is most consistent with complete steal?

A. Bidirectional “to-and-fro” flow
B. Early systolic deceleration notch
C. Continuous antegrade low-resistance flow
D. Entirely retrograde flow throughout the cardiac cycle

Correct Answer: D

Explanation: Complete subclavian steal is characterized by fully retrograde vertebral artery flow during both systole and diastole. Early steal presents as systolic deceleration or “bunny waveform,” while partial steal demonstrates bidirectional flow. Continuous antegrade low-resistance flow is normal. Identification of fully retrograde vertebral flow indicates significant proximal subclavian artery stenosis or occlusion and may correlate with arm claudication or neurologic symptoms during upper extremity exertion.

Which Doppler finding is most consistent with acute deep vein thrombosis (DVT) in the femoral vein?

A. Fully compressible vein with phasic flow
B. Noncompressible vein with hypoechoic intraluminal material
C. Echogenic wall thickening with collateralization
D. Continuous respiratory variation

Correct Answer: B

Explanation: Acute DVT is classically identified by a noncompressible vein containing hypoechoic or low-level echogenic thrombus. In early stages, the thrombus may be poorly attached and the vein may appear distended. Chronic DVT, in contrast, typically demonstrates echogenic thrombus, wall thickening, and collateral formation. Respiratory phasicity is usually reduced in acute proximal obstruction. Compression remains the primary diagnostic maneuver for acute DVT evaluation.

A lower extremity arterial Doppler waveform transitions from triphasic in the common femoral artery to monophasic in the superficial femoral artery. What does this suggest?

A. Normal physiologic variation
B. Proximal inflow disease
C. Distal high-grade stenosis
D. Vasospasm

Correct Answer: C

Explanation: A transition from normal triphasic waveform proximally to monophasic distally suggests a hemodynamically significant stenosis between the sampling sites. When distal arteries demonstrate dampened, monophasic waveforms with prolonged acceleration time, this indicates downstream flow limitation. Proximal inflow disease would alter waveforms at the common femoral level. The loss of multiphasic characteristics distally signals significant arterial obstruction affecting perfusion.

What ankle-brachial index (ABI) range is consistent with moderate peripheral arterial disease?

A. 1.00–1.30
B. 0.91–0.99
C. 0.41–0.69
D. <0.30

Correct Answer: C

Explanation: ABI values between 0.41 and 0.69 indicate moderate peripheral arterial disease. Normal ABI ranges from 1.00 to 1.30. Values 0.91–0.99 are considered borderline. An ABI below 0.40 typically reflects severe ischemia and may correlate with rest pain or tissue loss. Accurate cuff placement and Doppler angle alignment are essential to avoid false readings. ABI remains a foundational physiologic assessment in vascular diagnostics.

In a renal artery duplex study, which finding indicates ≥60% renal artery stenosis?

A. Renal-aortic ratio (RAR) <2.0
B. PSV >180 cm/s and RAR ≥3.5
C. RI >0.90 in segmental arteries
D. Absent diastolic flow

Correct Answer: B

Explanation: A renal artery PSV exceeding 180–200 cm/s combined with a renal-aortic ratio ≥3.5 is commonly used to diagnose ≥60% stenosis. The RAR normalizes velocity relative to systemic flow and improves diagnostic reliability. Resistive index elevation may reflect parenchymal disease rather than stenosis. Absent diastolic flow suggests severe distal resistance or occlusion. Accurate angle correction below 60 degrees is critical for valid velocity measurement.

Which waveform characteristic defines a normal high-resistance peripheral artery?

A. Continuous forward diastolic flow
B. Triphasic pattern with early diastolic reversal
C. Monophasic low-velocity flow
D. Turbulent spectral broadening

Correct Answer: B

Explanation: A normal high-resistance arterial waveform demonstrates triphasic flow: sharp systolic upstroke, early diastolic reversal, and late diastolic forward flow. This pattern reflects elastic recoil and peripheral resistance. Continuous forward diastolic flow suggests low-resistance circulation such as cerebral or renal arteries. Monophasic flow indicates downstream obstruction. Spectral broadening suggests turbulence often associated with stenosis.

Which sonographic sign supports chronic venous insufficiency?

A. Reflux lasting >0.5 seconds in superficial veins
B. Complete compressibility
C. Phasic respiratory variation
D. Hypoechoic intraluminal thrombus

Correct Answer: A

Explanation: Venous reflux lasting longer than 0.5 seconds in superficial veins or more than 1.0 second in deep veins is diagnostic for valvular incompetence. Chronic venous insufficiency often presents with reflux, dilated veins, and skin changes. Complete compressibility suggests absence of thrombosis. Hypoechoic thrombus suggests acute DVT. Proper Valsalva maneuver or distal augmentation is essential to elicit reflux.

Which finding is most suggestive of pseudoaneurysm on duplex imaging?

A. “Yin-yang” color flow pattern
B. Absence of Doppler signal
C. Uniform laminar flow
D. Triphasic waveform

Correct Answer: A

Explanation: A pseudoaneurysm demonstrates swirling bidirectional flow within the sac, producing a “yin-yang” appearance on color Doppler. Spectral Doppler at the neck shows a characteristic “to-and-fro” pattern. This occurs due to arterial wall disruption with blood confined by surrounding tissue. Recognition is essential following catheterization procedures. Untreated pseudoaneurysms may enlarge or rupture.

Elevated velocities at a dialysis graft anastomosis most likely indicate:

A. Graft maturation
B. Hemodynamically significant stenosis
C. Normal turbulent entry flow
D. Venous occlusion

Correct Answer: B

Explanation: Markedly elevated PSV at the arterial or venous anastomosis of a dialysis graft suggests significant stenosis, particularly if velocity ratios exceed 2:1 compared to adjacent segments. Early detection prevents thrombosis and access failure. Turbulent entry flow is expected but should not demonstrate extreme velocity elevation or aliasing extending beyond the anastomosis.

Which condition most commonly produces tardus-parvus waveform in the hepatic artery?

A. Portal hypertension
B. Hepatic artery thrombosis
C. Proximal celiac artery stenosis
D. Cirrhosis

Correct Answer: C

Explanation: Tardus-parvus waveform is characterized by delayed systolic upstroke and reduced peak velocity, indicating proximal inflow obstruction. In the hepatic artery, this pattern may result from significant celiac artery stenosis. Portal hypertension primarily affects portal venous flow. Complete thrombosis would eliminate detectable flow rather than produce dampened waveform morphology.

What is the primary advantage of using power Doppler in vascular imaging?

A. Measures flow direction
B. Quantifies velocity precisely
C. Increased sensitivity to low flow
D. Eliminates aliasing

Correct Answer: C

Explanation: Power Doppler displays the amplitude of Doppler signals rather than frequency shift, making it more sensitive to low-velocity or small-vessel flow. It does not indicate direction and is more susceptible to motion artifact. While it improves detection of subtle perfusion, it does not provide quantitative velocity data like spectral Doppler.

A popliteal artery aneurysm is diagnosed when diameter exceeds:

A. 0.8 cm
B. 1.0 cm
C. 1.5 cm
D. 2.0 cm

Correct Answer: C

Explanation: A popliteal artery diameter exceeding 1.5 cm or 50% larger than normal adjacent artery qualifies as aneurysmal. Popliteal aneurysms carry risk of thrombosis and embolization. Duplex evaluation includes diameter measurement and assessment for mural thrombus. Bilateral screening is recommended because of high association with contralateral aneurysm.

Which venous Doppler finding suggests proximal iliac obstruction?

A. Increased phasicity
B. Continuous nonphasic waveform
C. Augmented distal flow
D. Reflux with Valsalva

Correct Answer: B

Explanation: Loss of respiratory phasicity and continuous venous flow suggest proximal obstruction, such as iliac vein thrombosis or compression. Normally, lower extremity venous flow varies with respiration. When obstruction dampens transmitted pressure changes, flow becomes continuous. This indirect sign is important when iliac veins cannot be directly visualized.

Which maneuver best differentiates external carotid artery from internal carotid artery?

A. Measure PSV
B. Temporal tap maneuver
C. Assess ICA/CCA ratio
D. Evaluate plaque morphology

Correct Answer: B

Explanation: The temporal tap maneuver produces oscillations in the external carotid artery waveform when tapping over the superficial temporal artery. The internal carotid artery does not respond to this maneuver. Additionally, ECA demonstrates higher resistance waveform, whereas ICA has low-resistance continuous diastolic flow. Accurate differentiation prevents diagnostic errors.

Which parameter is most critical for accurate Doppler velocity measurement?

A. Color gain setting
B. Wall filter adjustment
C. Doppler angle ≤60 degrees
D. Sample volume size

Correct Answer: C

Explanation: Accurate velocity measurement requires Doppler angle correction of 60 degrees or less relative to blood flow direction. Angles greater than 60 degrees introduce significant cosine error, leading to overestimation. While gain and wall filter affect signal clarity, angle alignment is fundamental to valid quantitative assessment.

An ABI of 1.40 most likely indicates:

A. Severe PAD
B. Normal study
C. Noncompressible calcified arteries
D. Acute thrombosis

Correct Answer: C

Explanation: ABI values greater than 1.30–1.40 suggest noncompressible vessels, often due to medial arterial calcification seen in diabetes or chronic kidney disease. These falsely elevated values require alternative testing such as toe-brachial index. Such arteries resist cuff compression, producing misleadingly high pressure readings.

Which duplex finding is consistent with acute arterial occlusion?

A. Collateral vessels and echogenic plaque
B. Monophasic waveform with collateralization
C. Absence of flow with visible intraluminal echogenic material
D. Elevated PSV at focal narrowing

Correct Answer: C

Explanation: Acute arterial occlusion typically shows absence of color and spectral Doppler flow with echogenic or hypoechoic intraluminal material. Collateral formation develops in chronic disease. Elevated PSV indicates stenosis rather than complete occlusion. Rapid recognition is essential to prevent limb-threatening ischemia.

Which intracranial vessel is evaluated during transcranial Doppler through the temporal window?

A. Vertebral artery
B. Basilar artery
C. Middle cerebral artery
D. Internal jugular vein

Correct Answer: C

Explanation: The middle cerebral artery is commonly insonated through the transtemporal window during transcranial Doppler studies. It provides critical information in stroke evaluation and vasospasm monitoring. The basilar and vertebral arteries are typically accessed through the suboccipital window. Accurate depth and direction confirm vessel identification.

A velocity ratio of 3:1 across a femoral artery lesion most likely indicates:

A. <30% stenosis
B. 30–49% stenosis
C. ≥50% stenosis
D. Total occlusion

Correct Answer: C

Explanation: A peak systolic velocity ratio of 2:1 generally correlates with approximately 50% stenosis, while ratios of 3:1 or greater indicate hemodynamically significant narrowing exceeding 50%. Total occlusion would show absent distal flow. Velocity ratios compare stenotic segment PSV to proximal normal segment, providing reliable grading independent of systemic hemodynamics.

A renal duplex study demonstrates a peak systolic velocity of 420 cm/s at the proximal renal artery with a renal–aortic ratio of 5.2. Intrarenal waveforms show preserved systolic upstroke without tardus-parvus morphology. What is the most accurate interpretation?

A. No significant renal artery stenosis
B. Severe renal artery stenosis without parenchymal compromise
C. Complete renal artery occlusion
D. Intrarenal microvascular disease

Correct Answer: B

Explanation: A PSV >300–350 cm/s and renal–aortic ratio >3.5 strongly indicate ≥60% renal artery stenosis. Preserved systolic upstroke within intrarenal arteries suggests that perfusion remains adequate and there is no severe downstream parenchymal compromise yet. Occlusion would demonstrate absent flow, while microvascular disease typically elevates resistive index rather than proximal PSV.
