Royal Victoria Hospital Belfast Introduces Photon-Counting CT, Becoming Ireland's First Hospital to Adopt the Technology
Royal Victoria Hospital Belfast recently introduced the Siemens Healthineers NAEOTOM Alpha.Prime photon-counting CT scanner, becoming the first hospital in Ireland to adopt this next-generation CT imaging technology. The hospital is part of the Belfast Health and Social Care Trust, and this installation is part of a long-term value partnership between the hospital and Siemens Healthineers. According to reports, the NAEOTOM Alpha.Prime photon-counting CT delivers ultra-high-resolution images and spectral data at lower radiation doses. Its 0.2 mm slice thickness helps clinicians visualize small blood vessels, fine anatomical structures, and early pathological changes, enabling more diagnostic information to be obtained in a single scan...

South Korean Study Confirms Low-Dose CT Arthrography Reduces Radiation Exposure in Shoulder Examinations
A research team led by Professor Choi Jeong-ah from the Department of Radiology at Hallym University Dongtan Sacred Heart Hospital in South Korea has recently confirmed that low-dose CT arthrography can reduce patient radiation exposure by approximately 31% while maintaining high diagnostic accuracy, with diagnostic performance comparable to 3T magnetic resonance imaging (3T MRI). The findings have been published in the international musculoskeletal imaging journal *Skeletal Radiology*. Rotator cuff tears and superior labral anterior-posterior (SLAP) lesions are significant causes of shoulder pain; if not diagnosed and treated in a timely manner, they may lead to arthritis or decreased shoulder joint function. Currently, 3T MRI is commonly used for precise examinations, but it has drawbacks such as high cost, long examination times, and the potential for claustrophobia in some patients;...
