CT dose: How much is just enough?

Mahesh is currently involved in a follow-up to the 2009 NCRP report which is called Medical Radiation Exposure of Patients in the United States, and is expected to be released in November. The report should give an indication as to whether or not efforts to reduce dose have had a substantial impact in the last 10 years.

“From my experience, most imaging facilities attempt to meet the compliance of regulatory and accreditation bodies implementing the standards, whereas others strive to reach a balance between dose and image quality,” said Durairaj. “There is certainly a gap between facilities that try to achieve compliance versus those that go above and beyond all optimization fronts put forth by the regulatory and accreditation bodies.”

At the same time, vendors are also helping to ensure patients receive optimized doses by taking into account protocols, regulations and needs around CT dose in the technologies they develop. As iterative reconstruction and machine learning techniques continue to complement each other, some experts are hopeful that a new era of patient safety and dose optimization could be on the horizon.

"There are so many new, exciting, out-of-the-box technologies coming out in areas such as natural language programming, neural networks and quantum computing," said Wang. "They all may turn out to be very important, so it's very hard at this point to predict the future."
