The amount of time you spend with clinicians is practice dependent. At my institution, the NICU and PICU round every morning in radiology. We also participate in tumor boards and peds surgery conference.
The peds job market is opening up, now. Only a few years ago, though, the ACR said there were essentially no peds rads jobs.
Remember that even if you want to do peds radiology, you have to like all of it (only like 3 months are required in a 5 year residency).
Advantage to peds, you still get to be a generalist, but for little ones. Meaning, you’ll read plain films, ultrasound, ct, MRI, perform fluoro and do basic procedures.
In terms of payment, because the cross sectional volume is generally lower, peds radiologists generate fewer RVUs. I believe they’ll get paid about the same most places, but it requires RVU multipliers.
