https://medicalxpress.com/diagnostic-radiology-news/ en-us Latest medical news and research in Diagnostic radiology Biomedical engineers at Duke University have developed a technique to noninvasively visualize the brain's waste-removal system in unprecedented detail. This new imaging approach allows researchers to examine how this system is altered by conditions including ischemic stroke, aging and anesthesia in animal models, providing new insights into a system increasingly linked to neurodegenerative disease and brain health. This work is published in the journal Science Advances. https://medicalxpress.com/news/2026-06-tracking-cerebrospinal-fluid-reveals-unprecedented.html Tue, 23 Jun 2026 17:20:07 EDT news701447584 A group of researchers from the Technion and the United States reports a breakthrough in MRI scanning in a paper published in Nature Communications. The researchers developed an innovative method that accelerates and enhances MRI scans for breast cancer imaging, a disease diagnosed in approximately 2.3 million people each year, most of whom are women. https://medicalxpress.com/news/2026-06-faster-breast-mri-ai-image.html Tue, 23 Jun 2026 16:00:02 EDT news701440741 A liver cancer diagnosis frequently leads to surgery, with the goal of completely removing all malignant tissue. To ensure that no tumor remains in the organ, the resected tissue is subjected to frozen-section analysis during the procedure. This analysis takes time: Patients remain under general anesthesia throughout, operating room staff are occupied, and with every passing minute the risk of complications increases. https://medicalxpress.com/news/2026-06-ai-based-tissue-anomaly-duration.html Mon, 22 Jun 2026 15:20:03 EDT news701358601 Rudolf Virchow fundamentally changed medicine when he formulated his cell theory of disease in the 19th century: Diseases do not arise inexplicably within the organism, but rather in specific cells and tissues. To this day, pathology—the study of disease processes—is essentially based on the time-consuming examination of thin tissue sections, which are stained and then viewed under a microscope. https://medicalxpress.com/news/2026-06-ct-tissue-images-virtually-3d.html Sun, 21 Jun 2026 11:00:01 EDT news701017573 Alzheimer's disease is commonly known for its symptoms—memory loss, cognitive impairment, difficulty with daily tasks—but it can only be definitively diagnosed by looking at the brain. A scan must show the abnormal buildup of two distinct brain proteins, beta-amyloid and tau, and the presence of both distinguishes the disease from other forms of dementia. https://medicalxpress.com/news/2026-06-experimental-tau-tracer-alzheimer-linked.html Thu, 18 Jun 2026 18:00:02 EDT news701014121 Physicians and researchers at the Netherlands Cancer Institute have developed an AI model that outperforms physicians in evaluating treatment response in pleural mesothelioma. Far more accurate than the current international standard criteria (RECIST), the model provides patients with greater certainty and tailored treatments. It changes how physicians assess tumors and could accelerate the development of new treatments by making clinical trials more reliable and efficient. https://medicalxpress.com/news/2026-06-ai-heavyweight-tumor-mesothelioma-patients.html Wed, 17 Jun 2026 18:30:04 EDT news700900981 Canadian scientists have demonstrated for the first time that a noninvasive brain-monitoring technique could help medical teams predict the future development of premature babies. https://medicalxpress.com/news/2026-06-premature-babies-simple-gauges-neurocognitive.html Wed, 17 Jun 2026 12:00:09 EDT news700910521 Researchers at the State University of Campinas (UNICAMP) in São Paulo, Brazil, have identified a new biomarker that may help determine the prognosis for patients with gastric cancer, the fifth most common type of cancer worldwide. The team identified a variable that combines data on the radiodensity of visceral fat and muscle by analyzing images from computed tomography (CT) scans, a routine examination for these patients. This variable can distinguish those at higher risk of unfavorable disease progression. https://medicalxpress.com/news/2026-06-marker-tomography-refine-gastric-cancer.html Wed, 17 Jun 2026 11:40:05 EDT news700905601 Embolization of abnormal blood vessels using rapidly resorbable gelatin-based microspheres is safe and provides significant, lasting pain relief and functional improvement for patients with osteoarthritis-related knee pain, according to a new study published in Radiology. https://medicalxpress.com/news/2026-06-nonsurgical-procedure-relief-knee-pain.html Tue, 16 Jun 2026 10:00:03 EDT news700735021 Interpreting medical ultrasound images is a difficult task, requiring a technician to look at 2D images and mentally arrange them into a 3D representation of what the tissue looks like. To make that job easier, MIT researchers have developed a new approach to ultrasound imaging that allows the user to visualize a 3D augmented-reality image of the object being scanned. Using a virtual-reality headset, they can see a precise 3D digital representation of what the object actually looks like, making it easier to identify and analyze. https://medicalxpress.com/news/2026-06-augmented-reality-medical-ultrasounds-easier.html Wed, 10 Jun 2026 05:00:04 EDT news700237861 It might soon be "game over" for the video game controller. Yale researchers have developed a new kind of brain-computer interface (BCI) that lets humans play video games directly with their brains. Using real-time fMRI (functional MRI), they confirmed that the technology could help humans control a computer with their brain activity in a highly efficient way. The study appears in the journal Nature Neuroscience. https://medicalxpress.com/news/2026-06-brain-interface.html Tue, 09 Jun 2026 15:00:02 EDT news700235475 Three commercially available radiology AI systems have shown the potential to flag early signs of breast cancer up to six years before a diagnosis, according to a study published in Radiology. https://medicalxpress.com/news/2026-06-ai-early-breast-cancer-years.html Tue, 09 Jun 2026 10:00:04 EDT news700126983 Penn Engineers have developed an open-source algorithm that combines the speed of AI with the precision of geometry to compare complex medical images quickly and accurately, helping detect subtle changes that, over time, can signal disease. In some cases, the new algorithm can accomplish in minutes what would have taken prior techniques an entire week. https://medicalxpress.com/news/2026-06-fireants-faster-medical-image-analysis.html Tue, 09 Jun 2026 05:00:14 EDT news700150501 Women with abnormal mammograms often have to wait for weeks to find out whether they have breast cancer. Now, researchers at UC San Francisco and UC Berkeley have found a way to help reduce the wait and the worry by using AI to quickly identify those who are most likely to have the disease. By triaging these patients, the AI-guided workflow takes women with abnormal scans through the diagnostic process—from imaging to evaluation and sometimes even biopsy—in a single day. https://medicalxpress.com/news/2026-06-ai-breast-cancer-diagnosis-high.html Tue, 02 Jun 2026 18:00:05 EDT news699632762 Researchers at the USC Mark and Mary Stevens Neuroimaging and Informatics Institute (Stevens INI) at the Keck School of Medicine of USC have created one of the largest reference models ever developed for the human brain, using diffusion MRI scans from more than 54,000 people to chart how the brain's communication pathways develop, mature, and decline across the lifespan. https://medicalxpress.com/news/2026-06-brain-growth-white-human-lifespan.html Tue, 02 Jun 2026 13:40:04 EDT news699620087 Scientists at Johns Hopkins Medicine say they used a form of magnetic imaging to track cell therapy injections commonly used to treat certain autoimmune diseases and cancers. The findings, from a study of mice, add to a growing body of evidence that magnetic particle imaging (MPI), a new technique that allows scientists to visualize therapeutic cells as they inject them, may eventually help researchers personalize cell therapy treatments for individual patients. The study is published in Science Advances. https://medicalxpress.com/news/2026-06-magnetic-particle-imaging-tailor-cell.html Mon, 01 Jun 2026 15:20:06 EDT news699543045 Osteoporosis is a silent disease where bone loss develops gradually before fractures occur. Current clinical screening recommendations mainly focus on older women and selected high-risk groups, leaving some men, younger adults, and individuals with normal body weight completely outside routine screening pathways. https://medicalxpress.com/news/2026-05-ai-repurposes-routine-chest-rays.html Sat, 30 May 2026 17:00:02 EDT news699274705
