Question 1

Which Doppler waveform pattern is characteristic of a high-resistance peripheral artery in a normal resting adult?

Accepted Answer

Triphasic with reverse flow component

Answer

Normal peripheral arteries (e.g., femoral) show triphasic waveforms with a brief reverse flow component in diastole due to high downstream resistance.

Question 2

On a B-mode ultrasound image, a gallstone is typically identified by which combination of findings?

Accepted Answer

Echogenic focus with posterior acoustic shadowing and mobility

Answer

Gallstones appear as echogenic (bright) foci that cast a clean posterior acoustic shadow and move with patient repositioning.

Question 3

When scanning a patient with suspected deep vein thrombosis (DVT), the PRIMARY compression ultrasound criterion for acute thrombus is:

Accepted Answer

Non-compressibility of the vein lumen

Answer

Non-compressibility of the vein under transducer pressure is the gold-standard sonographic criterion for DVT diagnosis.

Question 4

A hypoechoic solid renal mass with internal vascularity on color Doppler should prompt the sonographer to:

Accepted Answer

Note the finding and recommend CT or MRI correlation

Answer

A solid vascular renal mass is indeterminate on ultrasound alone, requiring CT or MRI for characterization and staging.

Question 5

Which artifact causes a bright echogenic line at the same depth as the transducer face, obscuring near-field structures?

Accepted Answer

Reverberation artifact

Answer

Reverberation artifacts occur when sound bounces repeatedly between the transducer and a reflective surface, creating equally spaced echogenic lines.
