This term is used to describe certain pan-systolic arterial sounds
What is "bruit"?
100
This vein is not a true vein because it does not take blood directly to the heart
What is the "portal vein"?
100
This is required in order for blood to flow through a vessel or across a heart valve
What is "pressure gradient"?
100
This type of Doppler does not provide "range resolution" or discrimination of Doppler signals from different depths
What is continuous wave (CW) Doppler?
100
The symptoms of this pathology may mimic acute deep venous thrombosis, and it is frequently seen in patients with severe degenerative joint disease and rheumatoid arthritis
What is "Baker's (or popliteal) cyst"?
200
This describes the three broad categories of factors that are thought to contribute to thrombosis
What is "Virchow's triad"?
200
This lower extremity vessel is located in a fascial compartment and in the transverse view resembles an "Egyptian eye"
What is "long (or greater) saphenous vein"?
200
This Doppler value is often increased in acutely obstructed kidneys, demonstrating altered renal perfusion before the pelvicalyceal system dilates
What is "resistance index"?
200
This angle of insonation is assumed for transcranial Doppler
What is a "zero degree angle"?
200
These criteria are used to identify the vessels of the carotid bifurcation with ultrasound (name at least 3 of 5)
What are:
1. Location/orientation
2. Type of flow resistance
3. Visible branches
4. Size
5. Response to temporal tap
300
DOUBLE JEOPARDY!!!!!! This is the name of the randomized study reported in 1991 that verified the utility of carotid endarterectomy
in severe stenosis
What is "North American Symptomatic Carotid Endarterectomy Trial (NASCET)"?
300
This is the name of the structure adjacent to the brachial artery that is sometimes mistaken for a thrombosed vein
What is the "brachial nerve"?
300
This term refers to the type of flow where blood cells are moving at similar velocities over time, resulting in a well-defined pulsed Doppler spectral window
What is "laminar flow"?
300
It improves axial resolution in ultrasound imaging, increases lateral resolution, increases contrast resolution and reduces certain artifacts
What is "tissue harmonic imaging"?
300
This is the recommended width of the bladder of an inflatable blood pressure cuff (one of two answers are acceptable)
What is "40% of the circumference of the midpoint of the limb" or "20% wider than the diameter of the limb"?
400
These two words are used to describe the characteristics of a post-stenotic waveform, and in Latin means "late small"
What is "tardus parvus"?
400
The "banana peel" view is a coronal view used to image these abdominal blood vessels
What are the "renal artery origins"?
400
DOUBLE JEOPARDY!!!!!! The flow in this vessel changes from normally high resistant to low resistant post-prandially
What is the "superior mesenteric artery"?
400
This reduces when Doppler is steered, causing decreased sensitivity
What is "aperture"?
400
This term means that the study is positive, but those positive findings are not confirmed by the gold standard test results
What is "false positive"?
500
This term refers to clinical and histologic abnormalities occurring in response to acute obstruction of the hepatic vein flow
What is "Budd-Chiari syndrome"?
500
This artery is a branch of the (common) hepatic artery and lies anterior to the head of the pancreas
What is the "gastroduodenal artery"?
500
Mean velocities in the MCA are normally less than this velocity
What is "120 cm/s"?
500
This appears as a quickly fluctuating mixture of color Doppler signals imitating turbulent flow with a characteristic flat pulsed Doppler spectrum suggestive of noise. It occurs behind a strongly reflecting granular interface.
What is "Doppler twinkle artifact"?
500
This material causes a "snow storm" or noisy, echogenic appearance when dispersed in soft tissue, and may be seen in the upper extremity, axillary or subclavian areas - especially after trauma
