The global CT market is valued at $4.9 billion U.S. (4.62 billion euros) for 2016, according to a report by Kalorama Information.
The firm attributes growth to the increasing number of clinical applications for CT, an aging population, and more chronic disease.
Kalorama also covers the following recent developments in the CT market:
- A low rate in false-positive findings
- Children receiving fewer CT scans now than a decade ago
- More CT angiography (CTA) exams in the Medicare population
- The development of next-generation CT scanners that reduce potentially harmful radiation while still improving overall image quality
- The growing role of CT for advanced prostate cancer
![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)
