The first half of 2025 has drawn to a close, and once again it was an eventful period for radiology. As we do every year, we’ve compiled a list of the top six stories – one for each month – to help recap what was important in medical imaging.
Consolidation in Imaging Services
Radiology’s imaging services segment continues to consolidate as smaller providers get gobbled up by larger players. One of the biggest consolidation moves happened in April when Radiology Partners agreed to take over radiology contracts held by Envision Healthcare. Private-practice radiology continues its slow decline, as documented by a study in May that found just 50% of U.S. radiologists in private practice.
DeepHealth Drives AI Consolidation
Imaging services isn’t the only radiology market that’s consolidating – the AI sector is also seeing heightened M&A activity as algorithm developers suffer from a decline in venture capital activity and slower clinical adoption. Many of the deals are being driven by RadNet’s DeepHealth subsidiary, which continues to acquire independent AI developers, such as See-Mode Technologies in ultrasound and its proposed deal for iCAD in mammography.
Radiology VC Funding Goes Boom – Then Bust
Radiology venture capital funding appeared to be gaining momentum in the first few weeks of 2025, as January saw six funding rounds, but the good times didn’t last as economic concerns slowed investment. Radiology startups may have to get used to a more competitive funding environment, although there was positive news in the spring with funding rounds from HOPPR, DESKi, RadAI, Yunu, Aeon, Heartflow, Chipiron, Brainomix, and Brainreader.
When Will Getting Paid for AI Get Easier?
Reimbursement is one of the major stumbling blocks holding back wider adoption of clinical AI. Legislation that might grease the reimbursement skids was introduced into the U.S. Congress in April, but sources tell The Imaging Wire that it wasn’t included in the big budget bill that was just passed. In the meantime, AI developers and users will have to deal with a patchwork of AI reimbursement pathways.
Concerns Rise about CT Radiation Dose
Several studies were published in the first half of 2025 raising concerns about radiation dose from CT scans. First, researchers in April released a study that they claimed showed that all the CT scans performed in the U.S. in a single year would cause more than 100k cancers over the lives of the patients who got them. That was followed up with a paper in May linking greater CT use in European countries to a higher percentage of patients with five-year cumulative radiation dose of over 100 mSv.
Can Imaging IT Tools Help Radiologists Manage Rising Volume?
Radiology’s rising scan volume and static workforce have IT developers furiously working on tools to bridge the gap. A March paper listed the half-dozen IT tools radiologists say they want (only one was AI), but another analysis threw cold water on the idea by predicting that AI would actually increase radiologists’ workload, not reduce it. Meanwhile, multiple studies are showing that for applications like breast screening, AI can reduce workload by as much as 41%.
The Takeaway
The midpoint of the year is a great time to take stock of radiology’s progress and the issues that have bubbled to the surface over the past six months. AI dominated radiology for the first half of 2025, and odds are the trend will continue in the back half of the year.
