RadGPT Simplifies Radiology Reports for Patients

Posted on by Brian Casey

When it comes to informing patients of their imaging results, radiologists are caught between a rock and hard place. A new study in JACR shows how generative AI can help by drafting patient-friendly reports that are simple but accurate.

Patients must be informed immediately of their medical results according to a 2021 final rule under the 21st Century Cures Act that prevents medical information blocking. 

  • And while the technology exists to do that through tools like email and electronic patient portals, rapid notification can create confusion because the language physicians use to communicate with each other isn’t easily understood by anyone outside medicine.

Sure, radiology reports could be rewritten manually for patients, who typically read at about the eighth-grade level.

  • But given today’s workforce shortages, who’s going to do that?

Generative AI and large language models offer a solution. In the new JACR paper, researchers from Stanford University led by senior author Curtis Langlotz, MD, PhD, described their development of RadGPT, an LLM designed to improve patient communication.

  • To develop RadGPT, researchers started with OpenAI’s GPT-4 model and the RadGraph concept extraction tool to create an LLM that analyzes patient radiology reports and generates concept explanations and question-and-answer pairs.

How well did RadGPT work? The researchers tested it on 30 radiology reports generated at Stanford from 2012 to 2020, including different modalities and clinical applications. 

  • The LLM was asked to generate reports at a fifth-grade reading level (the level recommended by the Joint Commission for patient-facing healthcare materials).

Five radiology-trained physicians then rated the quality of RadGPT’s responses, finding …

  • The average rating of RadGPT-generated concept explanations was 4.8 out of 5.
  • 95% of concept explanations had an average rating of 4 or higher.
  • 50% of concept explanations were rated 5, the highest possible rating.
  • Questions and answers generated by RadGPT were also rated highly, with an average rating of 3.0 on a three-point scale..

The Stanford researchers told The Imaging Wire that their goal is to make RadGPT more widely available as part of a prospective evaluation with real patients.

  • They are also developing a user-friendly interface in which patients can receive hyperlinked radiology reports.

The Takeaway

RadGPT and solutions like it fill a desperate need for tools that can save time for radiologists while helping patients better understand their reports and get more engaged in their care. The next step is to get technology like this into the hands of practicing radiologists.

Reporting Rules at SIIM 2025

Posted on by Brian Casey

The annual meeting of the Society for Imaging Informatics in Medicine offered a great opportunity to take stock of the imaging IT segment. At SIIM 2025, radiology reporting solutions – many powered by AI – were among the most exciting technologies under discussion at Portland’s Oregon Convention Center. 

As we mentioned in our video highlights roundup, attendance seemed a bit lighter at SIIM 2025, perhaps due to the Portland location and timing before a holiday weekend. 

  • But the number of vendors exhibiting at SIIM 2025 cracked 100 for the first time in years, underscoring the meeting’s importance as well as the overall growth of the imaging IT segment as the rise of AI spurs startup creation.

Every SIIM conference provides a fascinating early look at the trends and technologies that will shape radiology’s future, and this year’s meeting was no exception … 

  • Radiology Reporting Rules. The report is the radiologist’s final product, and SIIM 2025 presentations highlighted how important it is to improve this process, especially with AI. An entire track on May 21 was devoted to AI-enhanced reporting solutions, and on the exhibit floor companies showed AI-enhanced solutions that interpret radiologist findings and create structured reports from them. 
  • Questions about AI Adoption. As with past SIIM conferences, questions persist about the pace of AI adoption as well as the FDA’s regulatory direction since the Trump Administration took over. In SIIM 2025’s keynote address, health policy expert Rohini Kosoglu urged SIIM and the radiology community to take a more active role in self-regulation of AI in the absence of stronger direction from the federal government. 
  • Cloud Adoption Gains Steam. There are no such doubts about cloud-based image management, as providers are getting over past concerns about the technology. One enterprise image management vendor told The Imaging Wire that 100% of their new system orders included some form of cloud component. On the other hand, imaging IT expert Herman Oosterwijk sees some imaging sites having “second thoughts” about cloud hosting. 

The Takeaway

The growing prominence of radiology reporting software at SIIM 2025 illustrates the heightened interest in imaging IT solutions that enhance radiologist productivity rather than assist them with interpreting images – a job many feel they can do well enough on their own. 

Intelerad’s Reporting Play

Posted on by Jake Fishman

Intelerad continued its M&A streak, acquiring radiology reporting company, PenRad Technologies, in a relatively small deal that might have a much bigger impact than some think.

PenRad has a solid share of the breast and lung cancer screening reporting segments, making it a target of a number of PACS vendors in recent years.

The acquisition is another example of Intelerad using its private equity backing to complete its informatics portfolio, following a series of deals that allowed its expansions into new clinical areas (cardiac, OB/GYN), regions (UK), technologies (cloud), and functionalities (image sharing, cloud VNA).

Adding PenRad will immediately give Intelerad three proven cancer screening reporting solutions to offer to its PACS customers, while bringing Intelerad into an untold number of PenRad accounts that it didn’t work with before now. 

The deal’s long-term impact will likely be dictated by how well Intelerad integrates and enhances its new PenRad technologies. If Intelerad is able to seamlessly integrate its PACS/worklist with PenRad’s dictation/reporting, it could create a truly unique advantage — especially if Intelerad expands its reporting capabilities beyond just cancer screening. 

Intelerad’s PenRad acquisition and Sirona’s unified radiology platform also highlight the differentiating role that integrated reporting might play in future enterprise imaging portfolios, although there aren’t many more reporting companies still available for acquisition.

The Takeaway

Informatics veterans might point out that it’s much easier to acquire a portfolio of companies than it is to integrate all that software — and they’d be correct. That said, most would also agree that Intelerad has assembled a uniquely comprehensive enterprise imaging portfolio and it would be extremely well-positioned if/when that portfolio becomes fully integrated.

Radiology’s Smart New Deal

Posted on by Jake Fishman

A new Journal of Digital Imaging editorial from UCLA radiology chair Dieter R. Enzmann, MD proposed a complete overhaul of how radiology reports are designed and distributed, in a way that should make sense to radiology outsiders but might make some folks within radiology uncomfortable.

Dr. Enzmann’s “Smart New Deal” proposes that radiology reports and reporting workflows should evolve to primarily support smartphone-based usage for both patients and physicians, ensuring that reports are:

  • Widely accessible 
  • Easily navigated and understood 
  • Built with empathy for current realities (info overload, time scarcity, mobility)
  • And widely utilized… because they are accessible, simple, and understandable

To achieve those goals, Dr. Enzmann proposes a “creative destruction” of our current reporting infrastructure, helped by ongoing improvements in foundational technologies (e.g. cloud, interoperability) and investments from radiology’s tech leaders (or from their future disruptors).

Despite Dr. Enzmann’s impressive credentials, the people of radiology might have a hard time coming to terms with this vision, given that:

  • Radiology reports are mainly intended for referring physicians, and referrers don’t seem to be demanding simplified phone-native reports (yet)
  • This is a big change given how reports are currently formatted and accessed
  • Patient-friendly features that require new labor often face resistance
  • It might make more sense for this smartphone-centric approach to cover patients’ entire healthcare journeys (not just radiology reports)

The Takeaway

It can be hard to envision a future when radiology reports are primarily built for smartphone consumption.

That said, few radiologists or rad vendors would argue against other data-based industries making sure their products (including their newsletters) are accessible, understandable, and actionable. Many might also recognize that some of the hottest imaging segments are already smartphone-native (e.g. AI care coordination solutions, PocketHealth’s imaging sharing, handheld POCUS), while some of the biggest trends in radiology focus on making reports easier for patients and referrers to consume.

Smartphone-first reporting might not be a sure thing, but the trends we’re seeing do suggest that efforts to achieve Dr. Enzmann’s core reporting goals will be rewarded no matter where technology takes us.
