The first finalist for Best Radiology Image is out of this world -- literally, it is the first x-ray taken in space.
The image was acquired during the Fram2 space mission led by 42-year-old cryptocurrency entrepreneur Chun Wang. The mission launched on March 31 from NASA’s Kennedy Space Center in Florida. On April 1, the all-civilian crew woke up, had breakfast, and “took a few x-ray images,” Wang wrote in a post on the social media platform X.

Sharp observers will note that the image bears a resemblance to the first x-ray ever taken by Wilhelm Roentgen of his wife Anna Bertha Ludwig's hand on December 22, 1895.
That was intentional.
“The crew members were informed of Wilhelm Roentgen’s first x-ray image and were excited to honor that pioneering achievement 129 years later by recreating the image in space,” said Jeanne Walter, vice president of marketing and sales for MinXray, the company that manufactured the portable x-ray machine used to acquire the image.
An analysis of the acquired data and images is still underway, and findings will be shared once the research is complete, Walter added.
PET scans identify people at early risk for cognitive decline. Image from Guilherme Kolinger, MD, of Life Molecular Imaging in Germany, et al.
The second finalist for Best Radiology Image comes from a study reporting that amyloid PET scans in individuals with early signs of Alzheimer’s disease can identify those at higher risk of cognitive decline.

The study was conducted by scientists at Lantheus subsidiary Life Molecular Imaging, with the image demonstrating how quantitative analysis can reveal additional insights beyond standard visual assessment in amyloid PET.
“To identify the region highlighted in red, an amyloid-negative population (at baseline) with subjective cognitive decline was assessed with a voxel-based analysis using standardized uptake value ratios (SUVRs). Then, the baseline SUVR images of amyloid accumulators versus nonaccumulators were compared. Amyloid accumulation status was defined using the Centiloid method and with a five-year follow-up,” lead author Guilherme Kolinger, MD, explained to AuntMinnie.
The results showed that accumulators exhibited higher baseline SUVR in the red-marked region, which corresponds to part of the precuneus, a brain area known to play a role in early Alzheimer's disease. This region overlaps with the Centiloid target region (shown in blue), underscoring the potential of this approach to enhance preclinical Alzheimer's disease assessment, Kolinger added.
Scientific Paper of the Year
Private Equity Acquisitions of Radiology Practices from 2013 to 2023: National- and State-Level Analyses. Khunte, et al, American Journal of Roentgenology, March 5, 2025. To learn more about this paper, click here.
First up in the finalists that the Minnies expert panel picked for Scientific Paper of the Year is a study that found that private equity firms acquired more than 150 radiology practices involving nearly 3,500 locations between 2013 and 2023.
Mihir Khunte and Yashaswini Singh, PhD, from Brown University in Providence, RI, were motivated by the rapid rise of private equity investment in health care in the U.S., in particular in physician practices, and a relative gap in rigorous data on how these trends affect radiology.
Compared with 2013, when 0.88% of all radiologists in the study were under private equity employment, the research duo reported that 11.7% of all radiologists nationally in 2023 were private equity-employed. The latter includes 12% of all diagnostic radiologists and 6.7% of all interventional radiologists who were under this employment.
“Private equity acquisitions may introduce efficiencies and capital improvements but also raise concerns regarding physician autonomy, higher cost of care, and shifts in clinical priorities with unclear benefit for patients,” Singh told AuntMinnie.
Projected Lifetime Cancer Risks From Current Computed Tomography Imaging. Smith-Bindman, et al, JAMA Internal Medicine, April 14, 2025. To learn more about this paper, click here.
The second finalist for Scientific Paper of the Year presented findings suggesting that cancers associated with radiation from CT scans could eventually account for 5% of all new cases annually. The fallout of the findings is included in the Minnies Most Significant News Event in Radiology category this year.
Led by Rebecca Smith-Bindman, MD, a group at the University of California, San Francisco developed a risk model based on approximately 93 million scans in 62 million patients in 2023.
The team found that approximately 103,000 radiation-induced cancers were projected to result from 93 million scans. Risks were higher in children and adolescents, yet higher CT use in adults accounted for most (93,000) radiation-induced cancers, the researchers reported.
“I would love to see radiology professional organizations step up and acknowledge the overuse [of CT scans], acknowledge the low-value imaging and try to come up with some strategies for how we can address this,” Smith-Bindman told AuntMinnie in a recent interview.
Best New Radiology Device
Magnetom Flow.Ace, Siemens Healthineers
The Magnetom Flow.Ace is an ultrapremium, wide-bore, 1.5 tesla high-performance gradient MRI system cleared for use in the U.S. in June.
The Magnetom Flow.Ace 1.5-tesla MRI scanner.Siemens Healthineers
The scanner is the company's first 1.5-tesla platform for MR imaging with a closed helium circuit and no quench pipe. The system has a 60 cm bore and is also the first Siemens MRI scanner to be marketed to the veterinary radiology community as well as for general radiology, with coils now available for both fields.
“The Flow.Ace is a combination of all the best that’s come before it. The lack of helium is what’s most exciting for us,” said Katie Grant, PhD, head of Magnetic Resonance at Siemens Healthineers North America.
The Magnetom Flow.Ace requires just 0.7 liters of liquid helium for cooling, compared with conventional MRI scanners, which require more than 1,000 liters. This feature is due to the magnet’s DryCool technology, the company said.
The system design also eliminates the need for a quench pipe. In conventional scanners, this is needed to safely allow large amounts of gaseous helium to escape directly into the atmosphere during an emergency shutdown. The company also highlighted that the Magnetom Flow.Ace reduces annual energy consumption by more than 30%, owing to the system's Eco Power Mode.
The Magnetom Flow.Ace was 17 years in the making, Grant noted.
Signa Sprint, GE HealthCare
First debuted at the International Society for Magnetic Resonance in Medicine in May, the Signa Sprint is an ultrapremium, wide-bore, 1.5-tesla high-performance gradient MRI system.

With a high-gradient performance of 65/200 per axis driving the system, the system is designed to deliver crystal-clear visualization of submillimetric structures, improved signal-to-noise ratio (SNR) on diffusion imaging, and includes deep-learning algorithms to support diagnostics and treatment response monitoring, the company noted.
“This new system supports clinicians’ shift to quantitative MRI and a deeper understanding of tissue characteristics,” said Fotis Vlachos, chief strategy, marketing, and commercial officer, MR, at GE HealthCare.
Signa Sprint features built-in AI technologies AIR Recon DL, Sonic DL, and AIR x, according to GEHC. The system aims to enable accelerated cardiac MRI through the use of deep-learning reconstruction techniques to help reduce the time and expertise needed to interpret scans and drive consistency and reliability.
As breakthrough cancer therapies get introduced and cardiac MRI becomes increasingly adopted in clinical routine, the demand for higher precision and speed in diffusion and functional imaging is driving MR beyond its current standard of care, according to the company.
The mission of Signa Sprint is to offer capabilities once available only with high-end 3-tesla MRI systems in a field strength that is considered standard for oncological and cardiological MR imaging, Vlachos noted.
Best New Radiology Software
Protect Her AI women’s health software platform, Covera Health
Our first finalist for Best New Radiology Software is an AI-powered women’s health software platform designed to identify early signs of breast cancer, cardiovascular disease, and osteoporosis on routine scans.
Making use of AI, Protect Her analyzes imaging studies that women are already undergoing, such as mammograms, chest CT exams, and x-rays. It then flags imaging signs and patterns that may otherwise be missed, according to Covera Health.
Protect Her utilizes AI-based analysis of routine imaging scans to detect early signs of breast cancer, cardiovascular disease, and osteoporosis.
For example, Protect Her can detect patterns on mammograms that can indicate early malignancies, the company said. What’s more, it can spot breast arterial calcifications on mammograms and coronary artery calcium (both markers of heart disease) on chest CT exams. It can also note signs of vertebral fractures, which are often missed in early stages and can indicate osteoporosis, according to the vendor.
"Protect Her is purposefully built around women’s imaging, supporting radiologists and their primary care partners in identifying and treating early signs of breast cancer, bone disease, and cardiovascular disease,” said Gerard Heath, MD, senior vice president and chief of staff at Covera Health.
Viz 3D CTA AI software, Viz.ai
