complete solutions already passed
Hemodynamics - correct answer ✔✔the study of blood moving through the
circulatory system
Doppler - correct answer ✔✔Evaluation of the presence, velocity (speed),
direction and character of blood flow within the vessels
Doppler shift - correct answer ✔✔the difference in the transmitted frequency and
the reflected frequency from the moving blood
Aliasing - correct answer ✔✔occurs when the doppler frequency shift exceeds
one half of the pulsed repetition frequency (PRF)
Hypoechoic - correct answer ✔✔producing less echoes and amplitude than
normal. Less bright
Hyperechoic - correct answer ✔✔Producing echoes of higher amplitude than
normal for the surrounding medium. More bright
echogenic - correct answer ✔✔the ability to create an ultrasound echo
Homogenous - correct answer ✔✔completely uniform in texture and composition
, heterogeneous - correct answer ✔✔uneven echo pattern, not uniform
anechoic - correct answer ✔✔without echoes (black)
lateral - correct answer ✔✔toward the side
medial - correct answer ✔✔toward the midline
proximal - correct answer ✔✔Closer to the point of origin
distal - correct answer ✔✔farther from the point of origin
inferior/caudal - correct answer ✔✔below, towards feet
superior/cephalad - correct answer ✔✔above, towards head
turbulence - correct answer ✔✔chaotic flow patterns
Reynalds number - correct answer ✔✔turbulence occurs when the number meets
or exceeds 2000
High resistance waveform - correct answer ✔✔sharp rise in flow velocity during
systole, rapid decline toward the baseline, and diminished diastolic flow
