What's your experience level with CT scanning, and where are you in the process of becoming CT registered with ARRT?

whether they meet the hard credentialing requirements and timeline for CT registry within six months of hire

adaptability and ability to function safely with minimal onboarding across different units

Walk me through how you'd handle an exam where the images don't look right on quality control and you're not sure if it's equipment or technique.

troubleshooting process and whether they escalate appropriately versus guessing

If you noticed an image sent to PACS wasn't fully verified or looked incomplete before the radiologist reviewed it, what would you do?

diligence and ownership over the last step before diagnosis, and willingness to catch and fix an error rather than let it pass

How do you handle being called in for a rotating or varied shift on short notice, and what would make you turn one down?
