Hypoechoic

A

not as bright as surrounded areas
ex. kidney hypoechoic compared to liver

24
Q

interface

A

boundary between 2 materials or structures

EX–use bright appearance of dat interfaces to differentiate body structures from each other

25

A

behind or posterior to the peritoneum
Pancreas,IVC,abdominal aorta, uterus,colon,adrenal glands,urinary system

34
Q

Reverberation

A

structure with acoustic impedance different from adjacent structure, which causes huge amount of reflection back to transducer.
