Drawn from the 3 open postings on this page. The ones that come up across several employers are near the top.
Walk me through how you perform a lower extremity venous duplex to rule out DVT.
What they are checking: Whether they know the full protocol, including compression, flow and augmentation, and don't skip segments.
How do you grade a carotid stenosis, and which measurements do you rely on?
What they are checking: Whether they understand velocity criteria and how to get accurate angle-corrected Doppler readings.
You find what looks like an acute DVT on an outpatient. What do you do before they leave?

How do you get good images on a patient who is very large, in pain, or can't lie flat?
What they are checking: Whether they can adapt technique and positioning to get diagnostic images on difficult patients.
Tell me about a time a study was hard to interpret. How did you make sure the reading physician had what they needed?

How do you prepare for the RVT or RVS credential, or how did you keep your skills sharp after earning it?
