The team's paper is published in the journal Proceedings of the National Academy of Sciences. https://medicalxpress.com/news/2026-07-brain-imaging-reveals-neural-networks.html Thu, 09 Jul 2026 16:50:01 EDT news702831222 A study provides significant evidence in the field of advanced cardiac imaging and clinical cardiology. It shows that the damage resulting from a myocardial infarction is not confined solely to the affected area, but may also extend functionally to remote regions of the ventricle. Identifying this dysfunction could have important implications, including improved prognostic assessment of patients, earlier detection of cardiac deterioration before symptoms or more evident changes appear, and the implementation of earlier and more personalized therapeutic strategies. The study was conducted by the INCLIVA Health Research Institute, the Clinical University Hospital of València, the University of Valencia (UV), the Universitat Politècnica de València (UPV), the Cardiac Imaging Unit of Ascires Biomédico Group, and the Ascires-UPV Joint Research Unit. https://medicalxpress.com/news/2026-07-myocardial-infarction-remote-regions-ventricle.html Wed, 08 Jul 2026 13:00:02 EDT news702724600 One of the uncomfortable truths about multiple sclerosis is that the part of the brain likely to reveal the most about the disease and how a patient will be affected has been mostly invisible to clinicians. https://medicalxpress.com/news/2026-07-ai-previously-invisible-cortical-lesions.html Tue, 07 Jul 2026 05:00:16 EDT news702543202 A study conducted by the Sant Pau Research Institute (IR Sant Pau) and Hospital de Sant Pau has identified for the first time in living individuals a brain pattern related to the tau protein that changes according to the stage of Huntington's disease.

The investigative team highlights that access can be influenced by service-time deserts in addition to traditional equipment deserts. The findings are published in the Journal of the American College of Radiology's (JACR) July issue. https://medicalxpress.com/news/2026-07-breast-imaging-facilities-high-deprivation.html Thu, 02 Jul 2026 13:20:03 EDT news702216421 For people at high risk of developing breast cancer, yearly mammograms may not be enough to detect tumors early.

Lower-income and safety-net participants experienced higher testing-related burden, with factors such as insurance and employment status associated with more discomfort or anxiety. The findings in the Journal of the American College of Radiology highlight opportunities to improve equity in screening. https://medicalxpress.com/news/2026-06-socioeconomic-patients-lung-cancer-screening.html Wed, 24 Jun 2026 20:20:02 EDT news701522965 The procedure was "remarkably" successful. That's how Cynthia Schraf-Fletcher, 74, describes her experience with genicular artery embolization (GAE), a minimally invasive procedure that treats chronic knee pain. Nearly a year after the outpatient surgery on her right knee, Schraf-Fletcher says the outcome is nearly identical to the total knee replacement she previously had on her left knee. https://medicalxpress.com/news/2026-06-chronic-knee-pain-genicular-artery.html Tue, 23 Jun 2026 22:20:01 EDT news701419068 A risk model that combines a mammographic artificial intelligence (AI) risk score with polygenic and clinical risk scores more accurately identifies women at high risk of developing breast cancer than clinical risk scores used alone, finds a new Kaiser Permanente study.

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.
