Flashcards in Scan Planes & Terms Deck (39):
1

Sagittal

Splits the body vertically into UNEQUAL left and right sections

2

Transverse

Splits the body into UNEQUAL top and bottom sections

3

Coronal/Frontal

Splits the body into UNEQUAL anterior and posterior planes

4

Echogenicity

the ability to produce an echo or reflections of the sound beam

5

Echogenic

containing structures that reflect high-frequency sound waves; a structure or medium that is capable of producing echos

6

Hyperechoic

denoting a region in which the echoes are stronger or brighter than normal or than the surrounding structures; the opposite of hypoechoic

7

What's the difference between hyperechoic and echogenic?

NOTHING!

8

Hypoechoic

a region in which the echoes are weaker or less bright or fewer than normal or surrounding regions; the opposite of hyperechoic

9

Isoechoic

having the same relative echogenicity as a surrounding structure

10

Anechoic

without echoes; used in terms of characterizing an organ or a mass when compared to the parenchyma around it

11

Heterogeneous

non-uniform; irregular, composed of mixtures of different kinds

12

Homogeneous

uniform; composed of the same element

13

Cystic

without echoes; will have smooth, well-defined borders, and posterior acoustic enhancement; used in terms of identifying abnormalities

14

The bladder is (cystic/anechoic) compared to the uterus, but a mass on an organ is (cystic/anechoic).

anechoic; cystic

15

Solid

echogenic shades of gray that represent internal tissue composition

16

Complex

contains BOTH cystic and solid tissue components

17

Acoustic enhancement

the appearance of sound waves that pass unobstructed through and beyond fluid; the manifestation of increased acoustic signal amplitudes returning from regions lying beyond an object that causes little or no attenuation of the sound beam

18

Attenuation

a decrease in intensity, power, and amplitude of a sound wave as it travels through a medium; attenuated sound will either scatter, diverge or absorb

19

Absorption

a component of attenuation; occurs when ultrasonic energy is converted into another energy form like heat; the sound beam decreases as it is absorbed into the medium

20

Shadowing

the reflecting or absorbing of a sound wave, creating an echogenic anterior surface and an anechoic posterior surface; shadowing is demonstrated distal to a structure

farther from the midline or to the side of the body

36

Proximal

closer to the point of origin or closer to the body

37

Distal

away from the point of origin or away from the body

38

Cranial

toward the head

39

Caudal

towards the feet
