Targeting the emerging issue of radiation exposure in medical imaging exams, an early session at the Society for Imaging Informatics in Medicine's Annual Meeting, June 2-5 in National Harbor, Md., will focus on tools to optimize radiation dose and quality.

Physicians ordering exams and radiology technicians carrying out the exams need a better understanding of the past radiation exposure a patient has been subjected to, and the exposure for the new exam, says Richard Morin, PhD, professor of radiology at Mayo Clinic in Jacksonville, Fla. "Certainly, one thing information technology can bring to the table is notification of past history of exams," he contends. "That, by itself, would be very important."

During the session "Radiology Dose & IT Safety" on the morning of June 2, Morin and colleagues from UC-Davis Medical Center and Brigham and Women's Hospital will discuss procedures to measure radiation and use the data to calculate dose estimates. They'll also talk about methods to reduce radiation while maintaining high image quality, using decision support tools, and national programs to compare dose indices.

The speakers also will explain the American College of Radiology's Dose Index Registry and how it can be used to enable clinicians to measure the dosage levels they use against peers. "This will spur changing of protocols for patient exams," Morin believes. "The tools are now available."
