Diagnostic Imaging: ch. 9 Ultrasound
Imaging Review Questions with correct
answers 100%
Anechoic - Correct Answers areas that do not generate an echo and will appear black on the
final image and usually represent fluid-filled structures
Attenuate - Correct Answers to reduce in force or degree; to weaken
Isoechoic - Correct Answers equal appearance to surrounding tissue
Hyperechoic - Correct Answers this type of tissue will create a strong echo and a bright image
Transducer - Correct Answers ultrasound probe that generates the sound waves and also serves
to receive the returning echoes
Annular Array - Correct Answers tansducers with crystals aligned in rings
Gain control - Correct Answers modifies the strength of the returning ultrasound echo
M-mode; motion mode - Correct Answers ultrasound display mode primarily used in
echocardiography
B-mode; brightness mode - Correct Answers ultrasound display mode that displays returning
echoes in as bright dots on the monitor with varying degrees of brightness corresponding to
intensity of the returning signal
