100
The technical term for a bloody effusion.
What is a complex fluid collection?
100
When setting up scanning one makes these choices: Frequency, blank, depth and gain.
What is depth?
100
If used skillfully, this artifact can help differentiate between tissues such as nerves and tendons.
What is anisotropy?
200
This tissue appears as railroad tracks in long axis.
What is a nerve?
200
A defect touching a bursal or articular surface but not both.
What is a partial thickness tear?
200
A serous fluid collection around a tendon is known as.
What is tenosynovitis?
200
This side to side maneuver of the ultrasound probe is commonly used to improve the resolution of a structure.
What is a tilting or wagging maneuver?
200
Reverberation off a metal object produces this artifact.
What is ring down or reverberation artifact?
300
This term describes the pattern within a given structure.
What is echotexture?
300
This condition may or may not be reliably see on ultrasound of the medial or lateral joint line of the knee.
What is a meniscal tear?
300
The echogenic description of an atrophied muscle when compared to a normal muscle.
What is hyperechoic?
300
The linear or curvilinear arrangement of these objects within a probe are critical to imaging.
What are crystals?
300
When the ultrasound beam reflects off bone, the tissue beneath is affected by this artifact.
What is posterior acoustic shadowing?
400
This term describes the insertional area of a tendon or ligament.
What is the footprint?
400
A commonly diagnosed condition of the lateral hip that is rarely seen and makes this host apoplectic.
What is a trochanteric bursitis?
400
When examining a mass with ultrasound, this finding has ominous implications.
What is increased vascular signal?
400
This function allows for side comparison of left and right sided structures.
What is dual screen imaging?
400
A harbinger of pathology, this finding occurs when a tissue abutting a tear in a tendon or muscle tear drops into the tear.
What is a sag sign?
500
One of three such structures in the extensor mechanism of the knee, this pad is name for its position relative to the patella.
What is the suprapatellar fat pad?
500
When present this structure may cause ulnar nerve compression at the elbow.
What is an anconeus epitrochlearis?
500
This frequently diagnosed syndrome falsely accuses the muscle it is named for of radiating leg pain.
What is piriformis syndrome?
500
In this extended field of view image the red structure in this well known interval is one of 2 “leaders” for its muscle.
What is the long head biceps tendon?
500
This probe function allows better visualization of structures not perpendicular to the probe by redirecting the ultrasound beam.
What is beam steering?
