{ "title": "Study Evaluates Diagnostic Accuracy of Photon-Counting Detector CT in Coronary Angiography", "excerpt": "Research finds photon-counting detector CT offers high sensitivity, specificity, and accuracy for detecting coronary artery stenosis. ", "body": "A recent study published in the American Journal of Roentgenology examined the diagnostic performance of standard resolution (SR) and ultra-high resolution (UHR) modes in coronary computed tomography angiography (CCTA) using photon-counting detector CT (PCD CT). Researchers analyzed data from 122 inpatients, totaling 1,613 segments for evaluation. The findings indicate a segment-level sensitivity and accuracy rate consistently above 89.6 percent for diagnosing coronary artery stenosis.\n\nThe study assessed images from 61 patients using SR (total of 788 segments) and 61 patients utilizing UHR (total of 825 segments). The image reconstructions included SRnormal and SR virtual non-calcium (SRVNCa) images for the SR exams, while UHR exams were categorized into UHRnormal and UHRthin images.

A large-scale study, presented today at UEG Week 2026, has identified distinct antibody patterns up to 10 years before the diagnosis of inflammatory bowel disease (IBD), potentially opening new avenues for earlier risk detection and providing insights into future disease course. IBD is a group of chronic conditions, including Crohn's disease (CD) and ulcerative colitis (UC), in which abnormal immune responses contribute to ongoing inflammation and damage in the digestive system. Although IBD is increasingly recognized to develop over a prolonged period before diagnosis, relatively little is known about the immune changes that occur during this time.

Antibiotic use from childhood through early adulthood was associated with higher odds of irritable bowel syndrome (IBS) at age 24, with the odds increasing as the number of antibiotic prescriptions rose, according to a new study presented today at UEG Week 2026. IBS is a common digestive disorder that affects more than 60 million people across Europe, causing symptoms such as abdominal pain and changes in bowel habits. Whilst previous research has suggested a link between antibiotic use and IBS, evidence on whether childhood exposure is associated with IBS in adulthood remains inconsistent. Much of the existing evidence relies on people recalling past antibiotic use, with a lack of population-based studies using objectively recorded antibiotic data across childhood.

AN EXPERIMENTAL vaccine designed to prevent invasive Escherichia coli infections in older adults has failed to demonstrate clinical efficacy in a large Phase III trial, despite generating robust and sustained immune responses. The E.mbrace trial, involving 17,701 participants across 20 countries, found no demonstrated protective benefit from the nine-valent ExPEC9V vaccine compared with placebo. Following a prespecified futility analysis, the study was terminated early, and development of the vaccine has been discontinued.
