Medical imaging vendors have successfully reduced radiation dose through a variety of new technologies, according to a new white paper from the Medical Imaging & Technology Alliance division of the National Electrical Manufacturers Association (NEMA) of Rosslyn, VA.
The white paper claims that the new advancements have led to dose reductions of 20% to 75% for many imaging procedures. The paper also restates the argument that the benefits from the use of radiation for medical purposes outweigh the potential risks of developing cancer from radiation.
Some of the more important technologies in reducing radiation dose include:
- The use of pulsed rather than continuous fluoroscopy, which has reduced patient dose by 50% to 75%
- Automated exposure controls that match dose to body size and thickness, reducing dose from 10% to 30% for routine CT scans and 50% for cardiac CT exams.
- Reduced-dose pediatric protocols based on patient age and weight that have reduced dose by up to 80% for infants and 50% for small children.

![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)
