A new study of a large pediatric cohort, including children younger than 6, found that combining PET/MRI findings with EEG results and a structured presurgical evaluation improved the identification of seizure-causing brain tissue and informed treatment decisions. This research was published in the August issue of The Journal of Nuclear Medicine. https://medicalxpress.com/news/2026-09-petmri-presurgical-lesion-pediatric-epilepsy.html Fri, 11 Sep 2026 23:20:02 EDT news708346804 Pelvic organ prolapse is a common but often overlooked condition that affects millions of women. It occurs when the tissues that support the pelvic organs weaken, allowing organs such as the bladder, uterus or rectum to shift from their normal position. Doctors can assess how severe the prolapse is, but existing tools do not provide much information about what's happening inside the tissue itself. https://medicalxpress.com/news/2026-09-based-scans-uncover-hidden-tissue.html Fri, 11 Sep 2026 13:40:07 EDT news708345061 An artificial intelligence model that analyzes women's past and recent annual 3D mammograms is more effective at predicting the five-year risk of developing breast cancer than a tool that uses only the most recent 3D mammogram, as well as an AI model that analyzes 2D mammograms, a new study shows. https://medicalxpress.com/news/2026-09-ai-imaging-tool-breast-cancer.html Thu, 10 Sep 2026 17:20:09 EDT news708268824 Researchers at Johns Hopkins Medicine have demonstrated a new approach to brain imaging that enables continuous monitoring of brain activity and the physiologic changes associated with neurological disease progression for more than 24 hours in freely moving mouse models.

By accurately mapping the extent of endometriosis, FAP-targeted PET/MRI has the potential to enable more personalized management and improve patient outcomes. https://medicalxpress.com/news/2026-09-petmri-approach-endometriosis-difficult-areas.html Thu, 03 Sep 2026 20:20:01 EDT news707652841 The recent flood of artificial intelligence (AI) models and content has undoubtedly introduced an unwelcome flaw from the human-made content it scrapes: bias. AI has been shown to form, copy and amplify harmful stereotypes of already marginalized groups. This phenomenon has far-reaching effects as AI becomes a normal part of everyday life. https://medicalxpress.com/news/2026-09-fragmented-bias-commercial-medical-ai.html Wed, 02 Sep 2026 09:20:01 EDT news707557114 Demand for medical imaging in the U.S. keeps rising, but the number of radiologists available to read those images has barely budged relative to the population, according to a study published in the Journal of the American College of Radiology. https://medicalxpress.com/news/2026-09-radiology-pipeline-slower-medicine.html Tue, 01 Sep 2026 19:20:05 EDT news707499662 When the brain is stimulated, blood flow increases. For 30 years, functional magnetic resonance imaging (fMRI), one of the most powerful windows into the human brain, has operated on the basis of this connection. fMRI doesn't actually see neurons firing; it tracks changes in blood oxygenation. https://medicalxpress.com/news/2026-09-brain-blood-differently-pain-mouse.html Tue, 01 Sep 2026 12:20:06 EDT news707475541 More than 40% of American women ages 40 and older have dense breast tissue, according to the National Cancer Institute. This type of tissue can make cancer harder to spot on mammograms and is itself associated with a higher risk of cancer. For some, additional screening may be appropriate. https://medicalxpress.com/news/2026-08-breast-density-laws-linked-higher.html Mon, 31 Aug 2026 11:20:02 EDT news707391121 A newly developed radiotheranostic pair, 68Ga/177Lu-NYM096, can identify tumors and effectively deliver targeted radiotherapy to patients with metastatic clear cell renal cell carcinoma (ccRCC).

This could help patients, families and clinicians know what to expect and plan future caregiving and living arrangements. Results are published in Neurology, an official journal of the American Academy of Neurology. https://medicalxpress.com/news/2026-08-mri-early-onset-alzheimer-disease.html Wed, 26 Aug 2026 16:00:04 EDT news706880274 Rhabdomyosarcomas are a rare form of cancer; however, the disease is responsible for about 60% of all soft-tissue sarcomas in children. Rhabdomyosarcomas are aberrant, malignant forms of muscle tissue. Early detection of bone marrow infiltration by tumor cells is crucial when planning treatment. https://medicalxpress.com/news/2026-08-alternative-bone-marrow-sampling-children.html Tue, 25 Aug 2026 17:00:02 EDT news706894681 Researchers have developed a tiny optical imaging probe designed for optical coherence tomography (OCT) inside blood vessels in the brain. With further development, the tiny probe—which is about the width of a pencil lead and the length of a grain of rice—could be used to acquire detailed information about vascular disease and devices such as stents implanted in the brain. https://medicalxpress.com/news/2026-08-tiny-rotating-probe-degree-optical.html Tue, 25 Aug 2026 14:00:10 EDT news706883042 MRIs are among the most accurate imaging tests used to diagnose brain tumors, and MRI-based monitoring of tumors guides critical treatment decisions. The clinical standard for measuring tumors often relies on either subjective evaluation or simplified two-dimensional (2D) measurements. However, for tumors with slow or irregular growth patterns, such as meningiomas, these 2D metrics can fail to capture the true tumor burden, with studies showing that 3D spatial analysis provides a more accurate picture of tumor progression. https://medicalxpress.com/news/2026-08-confidence-ai-brain-tumor-imaging.html Mon, 24 Aug 2026 15:00:09 EDT news706800254 Scoliosis is a condition characterized by an abnormal sideways curvature of the spine and most commonly develops during adolescence.
