With patient safety top of mind these days, radiology professionals are correct to focus on performing CT scans with less radiation. To that end, three recently published research studies highlight new protocols to do just that.
Radiation safety has been one of the top radiology stories in 2025 following several studies underscoring the links between medical radiation and cancer.
- The irony is that patient radiation exposure can be reduced dramatically using protocols that already exist – it’s just a matter of applying them consistently in the real world.
In the first paper, published in European Journal of Radiology, researchers share their MINDS-CAD protocol for coronary CT angiography.
- MINDS-CAD relies on tailoring contrast dose to patient weight and CT scanner tube voltage using a five-step process.
MINDS-CAD was tested with 112 obese patients getting clinically indicated CCTA with Siemens Healthineers’ Somatom Force dual-source CT scanner and Bayer’s Ultravist 370 contrast agent. Researchers found that compared to a conventional tube voltage-adapted protocol, MINDS-CAD…
- Achieved superior image quality according to cases rated “good” or “excellent” (86% vs. 75%).
- Generated fewer poor-quality scans (3.5% vs. 8.8%).
- Produced sharply lower radiation dose (99 vs. 386 mGy•cm).
- Saw no link between vascular attenuation and BMI or tube voltage.
In a second EJR paper, researchers from India tested the ability of an AI-based reconstruction algorithm to reduce dose in cerebral CTA exams.
- They used Philips’ Precise Image AI-based reconstruction protocol, which produces images resembling traditional filtered back projection scans while reducing noise like advanced iterative reconstruction methods.
In tests with 68 patients who got cerebral CTA at 100 kVp, compared to iterative reconstruction, Precise Image…
- Improved contrast-to-noise ratio 26%, signal-to-noise ratio 22%, and visual noise 16%.
- Generated higher image quality scores from radiologists.
- Generated an extremely low median effective dose of 0.785 mSv.
Finally, a third study – this one in Clinical Radiology – used a “double low” technique of low-energy 50 keV images on GE HealthCare’s Revolution Apex dual-energy CT scanner with TrueFidelity deep learning image reconstruction on 60 patients with cirrhotic liver disease.
- Compared with a conventional protocol, the double-low technique had 48% lower radiation entrance dose (4.10 vs. 7.88 mSv) and 32% lower contrast dose (67.3 vs. 99.1 mL), while image quality was rated higher.
The Takeaway
Taken together, the new papers show that radiology’s radiation dose challenge is eminently solvable thanks to the ingenuity of clinicians and researchers who are pioneering new ways to scan.

- AI Collaboration Network Launches: A Swiss startup is launching a new technology infrastructure that enables different AI developers to connect their algorithms into AI suites that function like integrated AI platforms. HealthCare Konnect’s TEO MultiLink is a collaboration layer that connects disparate AI algorithms to create networks that give clinicians access to a broader array of models than if they contracted with developers individually. The network also makes it possible for AI developers to cross-sell and co-distribute each other’s algorithms.
- Mental Health to Dominate DHAC Discussion: The next meeting of the FDA’s Digital Health Advisory Committee on November 6 will be dominated by a discussion of digital mental health technologies. The FDA last week released an agenda for the DHAC meeting that includes presentations on generative AI and digital mental health devices, regulatory considerations, and other issues. DHAC’s first meeting a year ago concentrated on generative AI regulation – especially post-market monitoring – with strong representation from radiology.
- Sirona Adds PET/CT to Viewing Suite: Sirona Medical received FDA clearance for Sirona Advanced Imaging Suite, which adds features supporting PET/CT exams to its diagnostic viewing software. The new package includes quantitative SUV analysis, image fusion, MIP generation, and multiplanar reconstruction. As with other Sirona solutions, Advanced Imaging Suite is cloud-based and can be deployed without the need for site-by-site installations.
- Lantheus Advances PET Radiotracers: Lantheus is reporting regulatory progress with a pair of PET radiopharmaceuticals it is developing. The company said the FDA accepted its New Drug Application for MK-6240, a fluorine-18 PET agent targeting tau in Alzheimer’s disease. Lantheus obtained MK-6240 through its 2023 acquisition of Cerveau Technologies. Separately, Lantheus reported the FDA set a target date of March 2026 for its review of NTH-2501 (gallium-68 edotreotide) for PET imaging of somatostatin receptor-positive neuroendocrine tumors.
- Opportunistic Detection of Liver Disease: Add liver disease to the list of clinical conditions that could be detected opportunistically from CT scans. In a new paper in eBioMedicine, researchers tested their liver adipose radiomic index algorithm for detecting early-grade hepatic steatosis, also known as metabolic dysfunction-associated steatotic liver disease. In a study of 859 people, LARI outperformed other CT-derived measures (AUC = 0.91 vs. 0.77-0.88). LARI analysis could be added to CAC or CT lung screening exams for early MASLD detection.
- How EggNest Protects the Cath Lab: Egg Medical presented real-world results at TCT 2025 showing that its EggNest Complete Radiation Protection System dramatically reduces occupational radiation exposure during cardiovascular procedures. Operators averaged only 0.16 mrem per case, requiring over 31k procedures to approach annual limits, while nurses and technologists received just 0.03 mrem per case. The system protects entire interventional teams from scatter radiation’s cancer and cataract risks while eliminating heavy lead aprons that cause orthopedic injuries.
- Mixed Results for Mammography Misses: A project testing whether digital reminders like text messages and videos would reduce missed screening mammography appointments had mixed results in a new study in JACR. Across 18.7k appointments, the overall rate of missed appointments fell slightly (from 29% to 27%), but missed exams rose in those who got text messages that didn’t require responses (35% vs. 22%). Patients who confirmed they got text messages had lower miss rates than those who didn’t respond (22% vs. 40%), perhaps a sign that digital literacy affected screening completion.
- CMS Finalizes 2026 MPFS with Cuts: CMS on Friday finalized its 2026 Medicare Physician Fee Schedule, which includes a controversial 2.5% cut in payment rates. CMS issued a proposed MPFS schedule in July, which, taken with other changes, would result in cuts of 3.8% for imaging and 1.8% for hospitals according to an analysis by Healthcare Administrative Partners. CMS said some HCPCS codes would be exempt from the efficiency adjustment, however.
- CIVIE Updates Texas Imaging Chain: Radiology operations software developer CIVIE received a contract to add RIS to its existing billing software installed at 14 Texas imaging centers operated by North Star Diagnostic Imaging. CIVIE believes a unified billing/RIS platform has workflow and efficiency benefits compared to using applications from different vendors. CIVIE was formed earlier this year after PE firm WindRose Health acquired Collaborative Imaging and rebranded the company.
- Biparametric MRI for Prostate Cancer: Another new study supports the use of a faster biparametric MRI protocol without contrast rather than multiparametric MRI for patients with suspicious prostate cancer lesions. Italian researchers in Current Problems in Diagnostic Radiology found that in 196 patients with at least one PI-RADS 3 lesion, there was no statistically significant difference in the overall diagnostic performance of three readers between bpMRI and mpMRI, and no patient progressed to metastatic disease or needed systemic therapy during follow-up.
- Medical-Grade AR Glasses Debut: German advanced visualization developer Snke OS is debuting its SnakeXR augmented reality glasses for medical applications. Unlike consumer AR technology that’s adapted for medical use, SnakeXR is built from the ground up for clinical use in areas such as orthopedics, neurosurgery, and interventional radiology. It includes technology such as surgical trackers, a built-in depth camera, an integrated headlight, and display transparency.
- Prostate MRI Software Scores CE Mark: Bot Image’s ProstatID AI solution for analyzing prostate MRI scans received CE Mark certification under the EU’s MDR framework. ProstatID identifies, quantifies, and classifies prostate lesions found on MRI scans, and could play a role in prostate cancer screening and patient management by helping providers determine which patients with elevated PSA levels should receive biopsy. Bot Image is working with European distributors and clinical partners for a launch of the software, which the FDA cleared in 2022.
- Fracture Detection AI Gets CE Mark: Czech AI developer Carebot received MDR CE Mark certification for Carebot AI Bones, its algorithm for detecting fractures on X-rays. Carebot is highlighting studies showing that AI Bones led to a 16% sensitivity increase in junior radiologists interpreting radiographs. The algorithm is available as part of the Horizon portfolio of AI applications that Carebot launched in September.
- Mammography Scandal in Spain: A scandal has erupted in the southern Spanish region of Andalusia after revelations that some 2.3k women with suspicious screening mammograms did not receive follow-up care. The scandal has led to public protests as well as the resignation of the region’s health minister, and has exacerbated political tensions between the regional and central governments. Spain’s health ministry has launched a review of cancer screening programs nationwide in response.
