In a normal lower extremity arterial Doppler waveform at rest, the spectral display typically shows which pattern?

On a carotid duplex examination, an internal carotid artery peak systolic velocity of 250 centimeters per second with spectral broadening most likely indicates which degree of stenosis?

During a venous duplex examination for deep vein thrombosis, the single most reliable sign of an acute thrombus within a vein is which of the following?

An ankle-brachial index is calculated by dividing the higher ankle systolic pressure by which value?

An ankle-brachial index value of 0.45 in a symptomatic patient is most consistent with which finding?

The internal carotid artery can usually be distinguished from the external carotid artery on duplex ultrasound because the internal carotid artery normally has which characteristic?

On a venous reflux examination, reflux is generally considered abnormal in a superficial vein when retrograde flow lasts longer than which duration?

According to Poiseuille's law, if the radius of a vessel is reduced by half while other factors stay constant, the resistance to flow will change in which way?

An abdominal aortic aneurysm is generally defined as a focal dilation of the aorta to a diameter of at least what measurement?

When evaluating a hemodialysis arteriovenous fistula with ultrasound, a markedly elevated velocity with post-stenotic turbulence at the arterial anastomosis most likely indicates which problem?

A common cause of an embolic stroke originating from the carotid artery is which of the following?

When imaging a deep abdominal vessel such as the aorta, the sonographer should generally select which transducer frequency?

Reversal of flow in a vertebral artery on the same side as a significant proximal subclavian artery stenosis is the hallmark of which condition?

The great saphenous vein joins the deep venous system at which anatomic location?

Spectral broadening on a Doppler waveform within a stenotic segment of an artery is best explained by which phenomenon?
