Which statement is FALSE regarding lower extremity arterial Doppler ultrasound?
- Disease may cause a low reversal wave component
- Normal PW Doppler shows a multiphasic waveform
- Areas of bifurcation are at low risk of developing plaque
- Angle correction is important for accurate measured velocity
- Areas of bifurcation are at low risk of developing plaque
List one reason why lower extremity arterial studies are performed.
My Ans: The patient with symptoms such as pain, edema, paralysis, parethesis, and pallor. Also the patients with clinical history of diabetes and chronic atheroscleosis.
True or False:
When imaging the posterior tibial artery and peroneal artery using PW Doppler ultrasound, a sonographer should expect to see at least two adjacent veins for each artery.
True

True or False:
Patients with claudication typically have chronic atherosclerotic disease.
True
When performing an arterial examination using CW Dopplers, why would you have your patient take a deep breath in and hold it?
- To help maintain a 60 degree angle with the probe
- To help the patient hold still
- To cease the venous signal and obtain a stronger arterial signal
- To avoid getting a high resistive arterial waveform
- To cease the venous signal and obtain a stronger arterial signal
True or False:
Indirect arterial testing allows quantification and specific location of disease.
False
