Dose Index Registry

The ACR Dose Index Registry (DIR) is one of eight registries that comprise the National Radiology Data Registry (NRDR). The DIR enables facilities to compare their dose indices data against regional and national values and to delve into details about scanner and device performance within and across facilities to ensure safe and high-quality exam performance for optimal patient care.

Published summary reports and real-time online reports let participants view aggregate performance data, pinpoint outlier exams, and identify performance patterns for further investigation. DIR performance reports facilitate implementation of quality improvement efforts and the database is used to explore a variety of topics for presentations and publications to advance the science and practice of radiology. 

The DIR offers quality measures to help fulfill Merit-based Incentive Payment System (MIPS) reporting requirements. Participation also meets Maintenance of Certification (MOC) Part IV requirements of the American Board of Radiology (ABR) and the Joint Commission’s dose benchmark requirement.

Announcements:  

  1. Hear from William F. Sensakovic, PhD, chair of the DIR and chair of the division of medical physics and associate professor at Mayo Clinic (Arizona), about the value of DIR participation. Read the article.
  2. Read the articles about the new DIR Fluoroscopy and DIR Digital Radiography modules. 

 

New DIR Modules

The DIR is expanding beyond CT!  A new DIR Fluoroscopy module now enables facilities to gain insight about their fluoroscopy procedure dose performance. Efforts are underway to offer more modules including DIR Digital Radiography and DIR Nuclear Medicine.  Check out the DIR Features Knowledge Base article to learn about new module developments.

Facilities participating  in one DIR module, can submit dose data to the other modules at no additional cost.

How to Participate


Visit the NRDR Knowledge Base article DIR Startup Guide for a  step-by-step approach to DIR participation—from assembling your team to reviewing your reports.  

Already a NRDR participant? Add the DIR to your facility registration. Only one registration is required to participate in any of the DIR modules.
