  • Swing shift:
    • 5 p.m. to 11 p.m. weekdays only
  • Weekend daytime:

Attending coverage:

24-hour in-house attending coverage of the ED reading room, with faculty on call backup available in all subspecialties.

Procedural call:

Residents take home pager call for image-guided procedural consults in conjunction with supervising interventional and procedural attendings for 1-week blocks at a time when on the Procedures rotation. Procedures are supervised by the on-call procedural attending.


All diagnostic (DR) and interventional radiology (IR) residents participate equally in responsibilities during the first through third years of radiology residency given the integrated nature of the programs.
