In a normal peripheral artery at rest, the Doppler spectral waveform is typically described as:

An ankle-brachial index (ABI) is calculated as the ratio of:

On a carotid duplex examination, a markedly elevated peak systolic velocity in the internal carotid artery with spectral broadening and post-stenotic turbulence most strongly suggests:

When performing a venous duplex study to evaluate for deep vein thrombosis, the single most reliable ultrasound finding for an acute DVT is:

Normal lower extremity venous flow is described as spontaneous and phasic. The phasicity of venous flow refers to:

A patient is referred for evaluation of a pulsatile abdominal mass. On ultrasound, an infrarenal aorta measuring 3.2 centimeters in maximum diameter would be classified as:

When optimizing a color Doppler image of a peripheral artery, if the color box appears to show aliasing within a normal vessel, the sonographer should first:

During a transcranial Doppler examination, the sonographer insonates the middle cerebral artery primarily through which acoustic window?

A duplex examination of a hemodialysis arteriovenous graft shows a markedly elevated velocity at the venous anastomosis with downstream turbulence. This finding most likely indicates:

The superficial femoral artery, despite its name, is functionally part of which arterial system in the leg?

According to the principles governing flow, when blood flows through a stenosis, velocity within the narrowed segment generally:

When grading internal carotid artery stenosis with duplex ultrasound, in addition to peak systolic velocity, sonographers commonly use which additional parameter?

A patient presents with leg swelling and on duplex the great saphenous vein shows reversed flow lasting more than 0.5 seconds after distal compression and release. This finding indicates:

To obtain accurate Doppler velocity measurements in an artery, the sonographer should keep the Doppler angle:

A continuous, low-resistance Doppler waveform with high diastolic flow is normally expected in which artery?

Segmental limb pressures are measured along the lower extremity to localize arterial disease. A significant pressure gradient between two adjacent cuff levels generally indicates:

A pseudoaneurysm, sometimes seen after arterial catheterization, is best described on ultrasound as:

During a renal artery duplex examination, an elevated peak systolic velocity in the renal artery combined with a high renal-to-aortic ratio suggests:

When performing a venous duplex study for DVT, the sonographer evaluates veins in transverse compression at frequent intervals because:
