Questions and Answers

Anechoic - ANS-Without echo; black, fluid filled structure

Acoustic Enhancement - ANS-Increased echo amplitude or "posterior through
transmission" visualized posterior to a structure that does not attenuate (decreased,
stop, impede, or absorb) the sound beam

Homogenous - ANS-Describes uniform or similar echo patterns of organ parenchyma
on a sonographic image

Acoustic Shadow - ANS-"Reduced echo amplitude" or "echo drop off" posterior to a
structure that attenuates [decreases, stops, impedes or absorbs] the sound beam

Heterogonous - ANS-Describes an irregular or mixed echo patterns of organ
parenchyma on a sonographic image

Acoustic impedance - ANS-Resistance a material provides to the passage of a sound
wave. "Bone portrays more acoustic impeded than tissue"

Hyperechoic - ANS-Comparative term used to describe an area in a sonographic image
where the echoes are brighter relative to surrounding structures.—Lots of echoes
BRIGHT WHITE

Complex - ANS-Composed of both tissue and fluid

Hypoechoic - ANS-Comparative term used to describe an area in a sonographic image
where the echoes are not as bright relative to surrounding structures.—Not so many
echoes GRAY-DARK

Cystic - ANS-Describes the sonographic appearance of a fluid collection within the body
and does not meet the criteria to be considered a true cyst

Isoechoic - ANS-Comparative term used to describe an area in a sonographic image
where the echo patterns are equal in echogenicity

Solid - ANS-Hard

, Echogenic - ANS-Describes a structure that is able to produce echoes or echo pattern.
Hyperechoic, hypoechoic, and anechoic are the terms used to qualify either an
abundance or absence of echoes displayed by a structure in a sonographic image

WNL - ANS-(Within Normal Limits) Results are within the range of what is considered
normal

DVT - ANS-(Deep Vein Thrombosis) A blood clot in a deep vein, usually in the legs

SVT - ANS-(Superficial vein thrombosis) is inflammation and clotting in a superficial
vein, usually in the arms or legs

Monophasic - ANS-Having a single phase; greatly increased velocity; through tight
stenosis

Biphasic - ANS-Having two phases; increased velocity, through mild stenosis

Triphasic - ANS-Having three phases; normal flow

RVT - ANS-Registered Vascular Technologist; perform non-invasive vascular exams in
order to assess for vascular disease or disorders


UE - ANS-(Upper extremity) the region in a vertebrate animal extending from the deltoid
region up to and including the hand, including the arm, axilla and shoulder

ABI - ANS-(Ankle-brachial index) test is done by measuring blood pressure at the ankle
and in the arm while a person is at rest; result is used to predict the severity of
peripheral arterial disease (PAD)

TCD - ANS-(Trans-Cranial Doppler) test measures how slowly blood is moving through
your cerebral arteries; Blood flows through these arteries to your brain

DCD - ANS-(Developmental coordination disorder) also known as developmental
dyspraxia or simply dyspraxia, is a chronic neurological disorder beginning in childhood
that can affect planning of movements and co-ordination as a result of brain messages
not being accurately transmitted to the body

EIV - ANS-(External iliac vein) large veins that connect the femoral veins to the common
iliac veins. Their origin is at the inferior margin of the inguinal ligaments and they
terminate when they join the internal iliac veins (to form the common iliac veins)

CFV - ANS-(Common femoral vein) large vein in the groin that passes with the femoral
artery under the inguinal ligament to enter the abdomen
