1

Anechoic

Echo free appearance

- bladder = compare to cysts

2

Echogenic

- produces echoes
- basis of comparing hyper and hypo
- hyperechoic
-hypoechoic

3

Hyperechoic

Echoes that are brighter than normal or brighter than normal or brighter than adjacent structures

-endometrium compared to myometrium

4

Hypoechoic

Structures that are not as bright as normal or less bright than adjacent structures

-fibroid compared to myometrium

5

Isoechoic / isosonic

Structures with the same relative echodensity

- liver and kidney cortex

6

Heterogeneous

Refers to and uneven echo pattern or reflections of varying echo densities

- kidney

7

Homogeneous

Refers to an even echo pattern of reflections that are relative and uniform in composition

- normal myometrium

8

Cystic

ALL of these characteristics
- anechoic
- through transmission
- smooth walls
- round
- ovarian cyst

9

Quasi-cystic

Appears cystic but misses THROUGH ENHANCEMENT due to small reflector echoes

- foam cyst of breast

10

Solid

Feeds to a structure or medium that is echogenic - contains echoes
Often attenuated the sound and causes a posterior shadow

-fibroids

11

Shadow

Refers to an area where no or little reflection is obtained, the area obscured

-IUCD

12

Enhancement

Refers to an area where there is little attenuation of sound
Good sound transmission
Behind appears clearer and brighter because it is better visualized

- behind urinary bladder
