I’m not a radiologist but honestly I’d have really loved an amazon card at the start of my internship so you can just get whatever you need. Pay as an intern sucks so having “free money” to use as you need or want is nice. Someone got me a gift card to the grocery store for my birthday once as an intern and I have to say, it sounds lame, but it was really nice to not have to worry about grocery costs that month and I got to splurge on food a little more than normal. A nice water bottle or lunchbox might also be a decent gift if they don’t have one. Other things that are nice for those of us that work more sedentary jobs are things like an ergonomic mouse, fancy chair, and a nice dictation headset but a lot of time your job will provide those.
