I'm currently a transitional intern at HCMC who's linked to the U of MN radiology residency. I would say that the year is challenging, but really good. This year we do 12 rotations (we switch every 31 days instead of every 4 weeks) and have 7 rotations that are q4. The radiology transitionals call months are: 2 months of medicine (either cards, general or MICU), 2 months of surgery, Psych, OB, peds. Then we have a month of neurology, 2 months of ED and 2 months of radiology.
Overall everyone at the hospital is awesome. It's a really laid back atmosphere, where everyone seems to have a good time, and almost everyone gets along. All of the attendings are really into teaching and every service LOVES having transitional interns on their service, because we have a great reputation in the hospital.
I was really nervous to start my transitional year here, and even though i wish i was on call less, it's a really good year and i've learned a lot while having a really good time.
I would say if you're really interested in the U of MN's radiology program don't let HCMC's intern year scare you away. It's a really good bonding opportunity for the whole intern class, and it's been a pretty fun year so far. Feel free to PM me if anyone has any questions.
