Diagnostic Ultrasound with correct
answers 100% 2026
What is an ultrasound? - Correct Answers Vibrations (of the same physical nature as sound but)
with frequencies above the range of human hearing
The diagnostic or therapeutic use of a non-invasive technique (involving sound waves) that
cause the formation of a two-dimensional image used for the examination and measurement of
internal body structures and the detection of bodily abnormalities
also sonography
non-invasive diagnostic technique used to image inside the body
Ultrasound probes, called transducers, produce sound waves that have frequencies above the
threshold of human hearing
Anatomical ultrasound produces images of internal organs or other structures
Functional ultrasound combines information such as the movement of tissue or blood, softness
or hardness of tissue, with anatomical images to create "information maps."
Blood flow maps - Correct Answers Diagnostic US
purpose is to interact with tissues in the body such that they are either modified or destroyed.
These destructive, or ablative, functions are made possible by use of very high-intensity waves
that can destroy diseased or abnormal tissues such as tumors or stones
The advantage of using ultrasound therapies include it being non-invasive
Kidney stones - Correct Answers Therapeutic US
How does an Ultrasound work - Correct Answers Ultrasound waves are produced by a
transducer
both emit ultrasound waves, as well as detect the ultrasound echoes reflected.
Using the speed of sound and the time of each echo's return, the scanner calculates the
distance from the transducer to the tissue boundary
, These distances are then used to generate two-dimensional images of tissues and organs
When do you order US/what are the pros? - Correct Answers soft tissue general detail - Soft
tissue mass, ligaments, tendons and soft tissue injuries 2 nd Best radiological study for soft
tissue masses Best for newer injuries/ trauma
What are the cons of US? - Correct Answers Longer study vs x-rays
Slightly limited availability - may take a few days to obtain depending on location unless
inhouse
Extremely Technician dependent
Limitations of US - Correct Answers Technique
Limited field view
Incomplete evaluation of bones and joints
Limited tissue penetration
Operator/Experience dependent
Lengthy training period
Diff dx that would warrant ordering US - Correct Answers ganglion cyst
neuroma
foreign body
What are some of the pros of using Xrays over US? - Correct Answers Relatively short study - 3-5
minutes No insurance pre-certification generally required* Most facilities have walk-in
appointments Cheaper Good for Bone/fractures
Cons of Xrays over US - Correct Answers Limited soft tissue evaluation (effusions, soft tissue
swelling, Achilles tendinosis)
