RadNet’s Joint Commission-accredited radiology services division, Imaging On-Call (IOC), offers a portfolio of solutions—including teleradiology, on-site staffing and credentialing.

IOC serves hospitals, research foundations, radiology groups, imaging centers, and urgent care centers.


IOC provides high quality, cost-effective, emergent and routine, daytime and nighttime interpretations to radiology groups, hospitals, and imaging centers. IOC is Joint Commission-accredited for final and preliminary reads. Board-certified, fellowship-trained radiologists are available 24/7/365.

Physician Staffing

IOC can be your full-service, on-site radiology department or used as a strategic supplement to an existing set-up. For example, a hospital can fill a sub-specialty, overflow, or vacation gap with resources from IOC.


Our flexible solutions for primary source verification and yearly reappointments are backed by the Joint Commission’s Gold Seal of Approval. IOC significantly reduces credentialing time for many of our clients.

“We have gotten our lives back. When the Emergency Department is a busy, 24×7 operation, the ability to turn the responsibility for preliminary reads to Imaging On-Call for seven hours a night has been essential. The service, uptime, and turnaround time have been excellent.”

Dr. Edward Lubat,
Valley Hospital, Ridgewood, NJ

Elite Corps of Radiologists

In addition to comprehensive image reading services through IOC, RadNet provides access to nationally-recognized physicians in radiology subspecialties and program development. We have attracted some of the top radiologists in the country, like Musculoskeletal-Orthopaedic radiologists Dr. John Crues and Dr. David Stoller, and that physician network collaborates to deliver the very best in patient care for our partners.

We also operate a prestigious MSK Fellowship program which supports orthopaedic and musculoskeletal programs nationwide.

RadNet has more industry resources—and talent—under one umbrella than any other imaging enterprise in the world.
