RSNA 2025 is wrapping up this week in what’s been a cold and snowy Chicago. While many attendees experienced travel delays getting into the show on Sunday, the disruptions didn’t slow the blistering pace of radiology innovation on display.
As has been the case all year in radiology, AI has been a hot topic at McCormick Place, both in the presentation rooms and on the technical exhibit floor.
- Much of the conversation is shifting away from individual point sources of AI – such as for analyzing images – and toward solutions that provide operational efficiencies such as faster radiology reporting.
But big iron has always been RSNA’s bread and butter, and RSNA 2025 didn’t disappoint.
- Major new product launches took place in the vendor exhibits, especially in helium-free MRI, photon-counting and spectral CT, and angiography, showing that vendors continue to invest in hardware development. Check out our coverage of the major OEMs in The Wire section below.
What were the other trends at RSNA 2025? They included…
- Growing buzz around new AI technologies like foundation and vision language models.
- Real-world clinical applications of AI such as triaging mammography screening.
- Growing momentum of CT lung cancer screening, both internationally and in the U.S.
- Use of generative AI to improve radiology reporting.
- Imaging’s contribution to greenhouse gas emissions – and how to reduce them.
- Imaging-based biomarkers that can predict future disease incidence.
- Opportunistic screening with imaging tests that can detect multiple diseases in one exam.
The Takeaway
Despite weather-related challenges, RSNA 2025 once again showed the importance of radiology’s showcase annual conference for bringing together academics, private-practice providers, vendors, and allied health professionals to meet, exchange ideas, and work together toward providing better patient care. It was great seeing everyone in Chicago – safe travels home!

- Early RSNA Attendance Figures: Attendance figures for RSNA 2025 show the meeting had 37.5k total attendees through Wednesday afternoon, of whom 19.4k were professionals (the category that includes radiologists). That compares to 39k total attendees through the end of the week at RSNA 2024. Given that a few more attendees typically show up in the last few days, it means that this year’s attendance is mostly on pace with a year ago, despite travel interruptions caused by the Chicago snowstorm.
- RSNA Scientific Session Highlights: There were a number of other highlights from the scientific sessions at RSNA 2025. Researchers found ultrasound can help detect vascular complications like occlusion that may occur after cosmetic surgery procedures. A Canadian team linked exposure to air pollution to early signs of cardiovascular disease based on cardiac CT exams. And another group correlated obesity with elevated levels of blood biomarkers and amyloid PET scans indicating a higher burden of Alzheimer’s disease.
- Predicting Patient No-Shows: Why do some patients never show up for their imaging exam – and can no-shows be predicted? That was one of the intriguing talks in a Tuesday afternoon session on noninterpretive skills (T7-SSNPM02). Researchers found a 15% no-show rate that they reduced 55% through an automated confirmation system. Another talk presented an online model for predicting CT volume and adjusting radiologist capacity, while nonphysician practitioners had higher repeat exam rates than radiologists for X-ray, ultrasound, and MRI. Finally, a study found higher malpractice rates in radiology for outpatient imaging.
- Imaging-Based Cardiac Biomarkers: RSNA 2025 attendees on Tuesday morning learned about imaging-based biomarkers that can predict cardiovascular disease (T3-SSCA05). Cardiac MRI detected patients with hypertrophic cardiomyopathy based on late gadolinium enhancement, while measuring epicardial adipose tissue on low-dose CT lung screening exams predicted major adverse cardiovascular events. The CCTA-based AI-CVD algorithm from HeartLung Technologies predicted cardiac events over 19 years by measuring cardiac chamber volume ratios, and German researchers correlated BMI and waist-to-hip ratios to cardiac structure and function on MRI scans.
- Issues in Emergency Radiology: Trending topics in emergency radiology were explored in another Tuesday morning session (T3-SSER01). Two presentations revealed how imaging can help detect victims of intimate partner violence, while another talk disclosed that jurors in a mock malpractice case were more likely to side with radiologists using AI if an image was read twice – with and without AI – rather than once with AI. Use of CT angiography for emergency cervical fracture evaluation grew from 2010 to 2022 (6.1% to 24%), while another study found that one-third of emergency exams for unhoused people had clinically significant findings.
- Focus on Radiology Reporting: Improving radiologist efficiency through better radiology reporting tools was the focus of a Tuesday afternoon series (T7-SSIN04). The Gaze2Report project uses visual-gaze tracking to guide large language models for report generation, while researchers presented their in-house LLM-based tool for tracking the performance of commercial AI algorithms for CT scans. AI-based reporting integrated into PACS worked well for chest X-ray and CT exams, while another group presented a method for extracting metadata from AI algorithms to use in structured databases of available models.
- Sessions Explore Screening Mammography: A series of Monday afternoon sessions explored the latest research in mammography screening (M7-SSBR04). An 11-year review of breast cancer trends at one institution found that 24% of cancers occurred in women under 40, while a Canadian study found women aged 40-49 had the lowest screening participation rates, with lower socioeconomic status depressing participation. New data from the ScreenTrustCAD study found radiologists using Lunit’s Insight MMG algorithm found more cancers than double-reading, and an AI model was used to detect breast arterial calcification on screening mammography and its connection to peripheral artery disease.
- Imaging and Sustainability: Imaging and sustainability was the subject of another Monday afternoon session (M6-SSNPM01). Short-term exposure to heat waves increased emergency imaging use by 3.3% in a Canadian study, while another paper found low-value lumbar spine MRI exams at one hospital produced greenhouse gas emissions equal to 32.5k miles driven in a gas vehicle annually. Meanwhile, research connected outdoor weather events to indoor particulate exposure caused by increased use of imaging equipment, and another study found radiology contributed 25% of one hospital’s total carbon footprint.
- Breast Density and Cancer Risk: The link between breast density and cancer risk was explored in a Monday afternoon session (M7-SSBR03). In one study, AI-based breast cancer risk scores began rising as early as six years before an eventual cancer diagnosis, while other research found volumetric breast density changes over time were more accurate than one-time measurements. The Mirai AI risk model predicted breast cancer better than BI-RADS breast density, and finally, the use of AI at multiple screening stages found more cancer in women with dense and nondense breasts.
- United Imaging Enters Ultrasound: United Imaging announced its entry into the ultrasound market at RSNA 2025 by launching the uSonique family of scanners. The company showed nine systems, ranging from cardiovascular to women’s health to general radiology; most are pending 510(k) clearance.
