A hallmark of Stony Brook’s imaging program is our low-dose scanning protocol. Although there is not a nationally identified threshold for how much radiation exposure from the average scan is too much, we believe that the safest approach is to use the lowest dosage possible without compromising scan quality. This is important for everyone, but particularly for children who are still developing and individuals who may require repeated scans.
Low dosages are dependent on two factors: speed of equipment and physician technique. Stony Brook continually upgrades its imaging equipment to acquire the fastest and most accurate on the market because faster equipment means less exposure to radiation. Our protocols were developed by Michael Poon, MD, FACC, Professor of Medicine and Radiology and Director of Advanced Cardiovascular Imaging. This internationally recognized physician-scientist honed low dose techniques over the course of his career. He has also trained the entire imaging team on perfecting the nuances of delivering the lowest dose possible for each individual patient.
For example on a typical CT scan, we can reduce exposure by up to 40 percent. Dr. Poon has also been able to perform extremely low dose cardiac imaging using a fraction of the radiation of more traditional protocols. This emphasis on patient safety, without sacrificing quality and accuracy, is the standard at Stony Brook. Learn more about typical adult radiation doses from common imaging exams.
