X-Ray Safety

Radiation exposure from X-ray examinations today is minimal. Contemporary X-ray systems deliver a very brief and narrow beam of radiation. Exposure is reduced by limiting beam size and exposure with lead shielding devices when appropriate and by limiting the duration of the exposure.

Though pregnant patients or pregnant personnel are of concern with respect to radiation exposure, the American College of Radiology states that there is no single X-ray procedure that results in radiation exposure intense enough to threaten the wellbeing of an embryo or fetus. 

MRI Prohibited Items

MRI safety is our utmost priority; we extensively monitor and test medical devices prior to patients entering an MRI scanner. The Radiology Group provides the following list of contraindicated MRI devices; this list is subject to change often and requires that we use the site for MRI safety for updates. We are transparent with the most current information on device testing and safety status. Read more for a brief registration of prohibited devices that will be a valuable tool when you are considering MRI safety.


A radiologist is a physician, a doctor, who has completed four years of postgraduate medical school, completed five years or more in a hospital residency program, passed the American Board of Radiology licensing examinations, and has often fulfilled a 1-2 year fellowship in a specialty field. A radiologist has completed at least 13 years of training and education.

26 radiologists work as doctors at TRG; we are all fellowship trained, and we each have a subspecialty that we excel in. This level of specialization is not always the case in imaging offices, often only seen in academia. Our medical imaging equipment is the most advanced in the industry, and we are always researching new improvements in the radiology field. We are trained in radiation safety and are expert in interpreting scans to detect and diagnose issues in the body before symptoms even arise. Scans are not only necessary to help physicians with an existing condition, but they serve as preventative services for those who are at higher risk for disease.

At TRG you are cared for by expert radiologists, by doctors who have years of training and study in their subspecialties that is specific to each patient who walks in our door.
