  Our Philosophy & Approach to Diagnostic Excellence

We believe that diagnostic excellence makes a difference in patients' treatment and outcomes. As such, we believe that every MRI, CT and nuclear medicine study should be read by a fellowship-trained, subspecialty radiologist who is an expert in his or her field. We realize the full importance of accuracy in our work and are committed to delivering it in every interpretation, every report and all communications for our patients and clients.

Further, we know that our clients' success is essential to our success and to that of our mutual patients. As a physician owned and operated practice, we are able to tailor our service and working relationship to meet your individual needs. Whether you are looking for an exclusive radiology provider, subspecialty radiology consulting or accreditation assistance, we can help you. When you partner with NationalRad, we are available to assist you in developing customized solutions to achieve your practice's goals.

  Our History

NationalRad was established in 1999 under the name NMSI (National Musculoskeletal Imaging) by Dr. Michael ZlatkinDr. Cary Hoffman and Dr. Gary Felsberg. The partners wanted to deliver dedicated subspecialty interpretations performed by the most qualified and highly respected subspecialty radiologists to the general clinical community at a time when such elite diagnostic medicine was only available at academic institutions. Dr. Timothy Sanders joined NMSI as a partner in 2003. The practice's name was officially changed to NationalRad in 2009 to reflect the addition of neuroradiology diagnostic services. We added body radiology to our list of subspecialties in 2010, with nuclear medicine to follow.

Our founders' and partners' steadfast commitment to providing the most accurate and thorough interpretations and superior customer service has been the foundation of our practice's growth and reputation over the past 15-plus years. Today, we provide subspecialty interpretations to more than 125 clients and are proud to be the subspecialty diagnostic radiology provider for physician practices, imaging centers and radiology groups nationwide. In addition, we are honored that professional and collegiate team physicians and orthopaedic surgeons continue to turn to NationalRad for their diagnostic radiology needs year after year.
