But what is it that, for example, allows an experienced birdwatcher to identify an uncommon species rapidly, at a distance and against a chaotic background in the wild? And what separates the gaze of a qualified brain surgeon from that of a first-year medical student? How is that kind of visual expertise acquired? https://medicalxpress.com/news/2026-07-surgeon-code-visual-expertise-ai.html Mon, 27 Jul 2026 07:40:01 EDT news704356501 The first photographs many parents have of their children are sonograms, used to check on the health of developing fetuses. These sonograms use noninvasive ultrasound technology, but the grainy, gray images they produce can lack diagnostic clarity. https://medicalxpress.com/news/2026-07-smarter-sonograms-generative-ai-advance.html Sat, 25 Jul 2026 11:00:04 EDT news703943557 Researchers in Korea have developed a new near-infrared (NIR) fluorescent dye with significantly improved photostability, overcoming the rapid signal fading that has long limited fluorescence imaging during surgery for cancer, lymph node mapping and other medical procedures.

In a cohort of more than 900 FUO patients, molecular imaging directly influenced clinical management in nearly 75%, contributing to improved patient outcomes, increased patient safety and reduced health care costs. https://medicalxpress.com/news/2026-07-molecular-imaging-diagnosis-fever-unknown.html Thu, 23 Jul 2026 19:20:04 EDT news704045701 The Pulmonary Embolism Reporting and Data Systems (PE-RADS) framework for diagnosing and classifying acute pulmonary embolism using CT and magnetic resonance (MR) angiography was published in Radiology. https://medicalxpress.com/news/2026-07-framework-pulmonary-embolism-patient.html Tue, 21 Jul 2026 10:00:10 EDT news703748665 Researchers presented an artificial intelligence (AI)-guided technique at the Society of NeuroInterventional Surgery's (SNIS) 23rd Annual Meeting that may improve the accuracy of delivering experimental therapies directly to malignant brain tumors. https://medicalxpress.com/news/2026-07-ai-technique-delivery-brain-tumor.html Tue, 21 Jul 2026 09:00:21 EDT news703842373 One of the biggest challenges in cancer research has been linking the "big picture" seen in medical scans with the microscopic biology that drives tumor growth and dictates how patients respond to treatment. Now, by combining multiple imaging techniques (PET scans, bioluminescence and fluorescence), scientists can detect tumors across the whole body simultaneously, pinpoint key targets and then examine those tumors in detail, including the surrounding cells and tissue. https://medicalxpress.com/news/2026-07-imaging-method-tracks-cancer-body.html Fri, 17 Jul 2026 15:40:04 EDT news703498329 A new study published in the Journal of the American College of Radiology (JACR) suggests that venture capital (VC) is playing a significant and growing role in driving innovation in radiology. The study, "Venture Capital Investments in Radiology from 2000–2023," found that a total of $11.4 billion was invested across 646 companies, with funding especially concentrated in medical devices, artificial intelligence health care software, and biotechnology and drug discovery. https://medicalxpress.com/news/2026-07-venture-capital-investments-radiology.html Fri, 17 Jul 2026 07:00:01 EDT news703482721 A study using positron emission tomography (PET) imaging has found that patients with schizophrenia had significantly lower muscarinic acetylcholine M1 receptor availability (about 13%–19%) across multiple brain regions than healthy individuals. Reduced M1 receptor availability affects several brain regions involved in cognition, learning, memory and executive function.

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.
