1) Anechoic- Describes the property of being echo-free or without echoes (sonolucent, echolucent).

2) Echogenic- The ability to create an ultrasound echo.

3) Hyperechoic- Producing echoes of higher amplitude than normal for the surrounding medium.

4) Hypoechoic- Producing echoes of lower amplitude than normal for the surrounding medium.

5) Isoechoic- Areas which have similar echogenicity to each other. An isoechoic "property" makes it more difficult to see the desired tissue structure.

6) Heterogenous- Mixed echoic pattern.

7) Homogenous- Uniform echoic pattern.
