The U.S. Food and Drug Administration (FDA) has launched the Center for Devices and Radiological Health (CDRH) Transparency Web site.
The site provides information about medical device and radiation-emitting product regulatory processes and decisions and summaries of data that provide the rationale for agency actions, according to the FDA. It includes information related to premarket submissions for approved and cleared products, postmarket performance and safety, compliance and enforcement, science and research, educational resources, and CDRH performance data.
The site also features a searchable total product life cycle database, which integrates premarket and postmarket medical device information from multiple data sources into a single snapshot. In the coming months, the FDA said it will expand the CDRH Transparency Web site to include premarket approval and clearance reviews.

![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)
