Radiology-Diagnostic Curriculum and Affiliations

Our program is a collaborative effort between Valleywise Health and Dignity Health St. Joseph's Hospital and Medical Center. We are a fast-paced Level I trauma centers in central Phoenix with a high-volume emergency department treating more than 80,000 patients yearly.


In the PGY-2 year, residents begin their radiology training on day one by dictating studies immediately. Residents rotate through all of the core building blocks prior to starting call, with an upper level rotating with them on abdomen, chest, and MSK. First year radiology residents (PGY 2) are never unsupervised and begin taking weekend day call half way through the year side-by-side with an attending and an upper level resident.  Residents will have rotations at St. Joseph's Hospital and Medical Center (SJHMC) and Valleywise Health.  The typical PGY-2 schedule is as follows:

Year 1

  • 8 weeks – Abdomen X-ray/CT
  • 8 weeks – Musculoskeletal X-ray/CT
  • 8 weeks – Chest/Cardiac CT
  • 4 weeks – Ultrasound
  • 4 weeks – Pediatrics
  • 4 weeks – Neuroradiology CT
  • 4 weeks – Neuroradiology MRI
  • 4 weeks – Nuclear Medicine
  • 4 weeks – Emergency Radiology
  • 4 weeks – Interventional Radiology

Second year radiology residents (PGY 3) begin to take evening call with in-house faculty supervision and overnight call with attending radiologists a phone call away. PGY-3’s are able to begin developing their leadership skills by providing guidance and mentorship to first year radiology residents and medical students. The typical PGY-3 schedule includes the following rotations:

Years 2 – 3

Includes core rotations as well as rotations in the following areas:

  • Body MRI
  • Cardiac and Chest MRI
  • Musculoskeletal MRI
  • Night Float
  • Spine Intervention
  • Women’s Imaging

Third year radiology residents (PGY IV) are able to further explore subspecialties within radiology throughout the year. Third year residents act as mentors to the first and second year residents and are able to explore leadership roles. The third year call schedule is much less intense than the second year call schedule and is front-loaded to allow residents ample time to study for the CORE exam at the end of the year.

Fourth year radiology residents (PGY V) act as leaders and mentors throughout the year. They are able to customize their fourth year to their subspecialty of choice and have a high degree of freedom when choosing rotation schedules.

First years can expect to take weekend day call (7 a.m.-7 p.m. or 5 a.m.-5 p.m.) one weekend every four weeks, starting approximately in November of the first year. This call is supervised by an attending and you may, depending at which site you are at, have an internal moonlighter colleague to help you out. The remaining weekends are free to do as you like! During the second half of first year and beyond, residents also have occasional “Short Call” shifts. These are from noon to 10 p.m. on a weeknight, but the residents then get the following day off as post-call.

Second years and beyond take weekend night call and weekday nights. Weekday night assignments are 1 week at a time. At first your nights will be supervised by an attending, but eventually you will take independent overnight call.


All residents will be required to participate in a QI project and scholarly project, as per ACGME requirements. Additional opportunities are numerous and encouraged, but not required. Funding for research/conferences are available through the program.
