The American College of Radiology (ACR) has earned Health Information Trust Alliance (HITRUST) r2 certification for its ACRedit Plus accreditation platform and its National Radiology Data Registry (NRDR), validating the organization's information security and data protection practices.
HITRUST offers what it calls a Common Security Framework certification, which requires organizations to demonstrate compliance with regulatory requirements and industry security standards through a risk-based framework.
ACRedit Plus provides accreditation services to more than 37,000 entities across nine imaging modalities, while NRDR serves over 3,800 facilities across eight quality registries, including Assess-AI, a registry focused on monitoring AI algorithm performance in clinical practice, the ACR said.
![Axial images from unenhanced calcium score cardiac CT (left) and curved planar reformation images from CT angiography (right) show that higher long-term exposure to air pollution is associated with greater coronary artery calcium and more obstructive coronary artery disease (CAD). Top row: Images in a 68-year-old male patient with higher 10-year mean ambient air pollution exposure (7.9 μg/m3 for particulate matter measuring ≤2.5 μm in diameter [PM2.5] and 17.4 parts per billion [ppb] for NO2) with extensive CAD (coronary artery calcium score [CACS] >1,000 and obstructive CAD [≥70% diameter stenosis]). Bottom row: Images in a 57-year-old female patient with lower 10-year mean ambient air pollution exposure (6.3 μg/m3 for PM2.5 and 4.6 ppb for NO2) with no CAD (CACS = 0 and no obstructive stenosis).](https://img.auntminnie.com/mindful/smg/workspaces/default/uploads/2026/06/hanneman.r6SMLzkezo.png?auto=format%2Ccompress&dpr=2&fit=crop&h=167&q=70&w=250)
