Less than two years after its launch, the American College of Radiology (ACR) Dose Index Registry (DIR) has added more than 5 million CT scans and nearly 3 million exams.
The DIR is designed to provide standardized, size-adjusted CT dose indexes to facilitate comparisons, allowing imaging facilities to compare their CT dose indexes to regional and national values.
Currently, the DIR has more than 600 registered facilities, including private practices, hospital-based facilities, and academic centers. Participation in the DIR is voluntary and will help radiologists meet the requirements for a Physician Quality Reporting System registry starting in 2014.
