https://medicalxpress.com/diagnostic-radiology-news/ en-us Latest medical news and research in Diagnostic radiology In a new study published recently in the journal Nature, researchers at Vanderbilt University and Vanderbilt Health have created the first growth charts for white matter in the brain over a human lifetime. The work brings together nearly two decades of Vanderbilt research collaborations, the university's extensive MRI data collections, and an advanced AI-enabled computing platform. https://medicalxpress.com/news/2026-05-brain-reveal-lifetime-white-growth.html Thu, 28 May 2026 13:20:02 EDT news699191039 Two researchers at the Institute for Neurosciences (IN), a joint center of the Spanish National Research Council (CSIC) and the Miguel Hernández University of Elche (UMH), have developed a new strategy based on artificial intelligence and computer simulations that makes it possible to obtain detailed brain information more quickly from MRI scans using far less data than usual. The method, published in the journal Communications Medicine, can reduce the time required for certain advanced MRI scans by up to 90% while maintaining a high level of accuracy, paving the way for more efficient and accessible neuroimaging in clinical settings. https://medicalxpress.com/news/2026-05-ai-simulations-advanced-brain-mri.html Wed, 27 May 2026 17:40:03 EDT news699118742 Engineers at the University of California San Diego have created a soft, wearable ultrasound patch that can continuously monitor a fetus for hours at a time—and it can do so consistently even as the fetus and umbilical cord constantly move during pregnancy. https://medicalxpress.com/news/2026-05-wearable-ultrasound-patch-high-pregnancies.html Tue, 26 May 2026 05:00:01 EDT news698917441 A team of researchers from Carnegie Mellon University, in collaboration with Cleveland Clinic's Cardiovascular Innovation Research Center, has developed an artificial intelligence (AI) system capable of interpreting some of the most complex heart scans in medicine, cardiac magnetic resonance imaging (MRI), without the need for manually labeled training data. https://medicalxpress.com/news/2026-05-ai-cardiac-mri-manual-general.html Thu, 21 May 2026 05:00:03 EDT news698480052 Catching pancreatic cancer early can increase the five-year survival rate from 15% to 80%. Patients with pancreatic cysts, frequently detected during unrelated abdominal CT or MRI imaging, can develop malignant pancreatic cancers. In a new study, Mass General Brigham investigators showed that patients with low-risk pancreatic cystic lesions (PCLs) have approximately 14 times higher risk of developing pancreatic cancer than the general population. https://medicalxpress.com/news/2026-05-early-cysts-pancreatic-cancer-sooner.html Wed, 20 May 2026 17:00:03 EDT news698511062 Millions of people are diagnosed with Alzheimer's disease each year, comprising 60% to 70% of dementia cases worldwide. While cognitive impairment and structural brain changes are indicative of Alzheimer's disease progression, the process to accurately predict who will develop Alzheimer's is time-consuming and requires a variety of techniques, including brain imaging, blood biomarkers, and neurocognitive testing by a neuropsychologist. https://medicalxpress.com/news/2026-05-baseline-mri-ai-alzheimer-cognitive.html Mon, 18 May 2026 16:20:06 EDT news698337001 When a person first exhibits signs of having a stroke, the timing of treatment is critical to restore blood flow to the brain and support recovery. In addition to studying and implementing ways to treat patients faster, investigators have been studying how to make predicting and treating stroke more precise. A new study in the journal Stroke introduces a concept of brain imaging known as blood-brain core imaging, or "leaky core," that could potentially accelerate this progress and transform the way that many strokes are treated. https://medicalxpress.com/news/2026-05-blood-brain-barrier-scans-personalize.html Sat, 09 May 2026 05:07:55 EDT news697522019 New multiplexed imaging technology using standard clinical MRI systems can simultaneously map more than 20 biomarkers in high resolution, providing a comprehensive view of the brain with a single scan. https://medicalxpress.com/news/2026-05-mri-technology-brain-biomarkers-minute.html Wed, 06 May 2026 17:40:01 EDT news697303562 Researchers at the Champalimaud Foundation in Lisbon have for the first time managed to identify with an imaging technique whether nervous impulses in the brain of rats are flowing in a "bottom-up" (feedforward), carrying information about visual input, or a "top-down" (feedback) direction, carrying information about expectations or predictions on a given task or about the perception of the world around us. Their results, published in Nature Communications, could have important implications for understanding changes in the brains of people with hallucinations, Alzheimer's, schizophrenia, autism, and other conditions. https://medicalxpress.com/news/2026-05-ultrafast-mri-uncovers-brain-scan.html Mon, 04 May 2026 10:20:08 EDT news697107961 A Concordia-led team of researchers has developed a new AI-driven robotic system that can perform cardiac ultrasound scans autonomously. The researchers say this approach could expand access to cardiac imaging in remote or underserved areas, reduce operator fatigue, and standardize scan quality. The work is published in the journal IEEE Transactions on Medical Robotics and Bionics. https://medicalxpress.com/news/2026-04-ai-powered-robotic-heart-ultrasounds.html Thu, 30 Apr 2026 17:40:01 EDT news696779341 An AI model (REDMOD) can pick up the very early subtle tissue changes of pancreatic ductal adenocarcinoma, the most common form of pancreatic cancer, which conventional imaging and the human eye find difficult to detect, finds research published online in the journal Gut. https://medicalxpress.com/news/2026-04-ai-invisible-tissue-pancreatic-cancer.html Tue, 28 Apr 2026 18:30:04 EDT news696590420 Ultrasounds are a critical part of modern health care, helping to image soft tissue and organs, measure blood flow, and monitor fetal development. But the technique has constraints, including a limited field of view and the potential for operator error. To address current shortfalls and push the technology toward new applications, Lihong Wang, Bren Professor of Medical Engineering and Electrical Engineering, and a team of Caltech researchers have developed a system that can perform ultrasound tomography (UST) imaging on whole cross-sections of the body. https://medicalxpress.com/news/2026-04-body-ultrasound-captures-full-sections.html Fri, 24 Apr 2026 17:00:07 EDT news696249902
