Germany orders 20% reduction in DRLs for radiation dose
August 25, 2016 -- Stating that more progress is needed in reducing patient exposure to radiation dose, German regulatory authorities on Tuesday announced a 20% reduction in diagnostic reference levels (DRLs) for radiation from medical imaging procedures. The move could require some facilities to replace aging equipment.
Total scans at Rio Olympics exceeded 1,500
August 24, 2016 -- On the final day of the Olympics in Rio, the number of imaging procedures burst through the 1,500 barrier, said Chief Medical Officer Dr. João Grangeiro. By 5 p.m. Brazil time on Sunday, 862 MRI, 460 x-ray, and 178 ultrasound exams had been performed.
Germans support single-source dual-energy CT for gout
August 19, 2016 -- Good news: In patients with gouty arthritis, single-source dual-energy CT has good sensitivity and high specificity to detect uric acid depositions, obviating the need for digital radiography or conventional CT, German researchers have found.
How low can CT radiation dose go for lung screening?
August 18, 2016 -- We're making progress in the race to reduce radiation dose for CT lung cancer screening to ever-lower levels. But as dose drops, image noise grows. Fortunately, researchers are refining image processing techniques that can improve image quality while driving CT dose down to the level of a chest x-ray.
Thorax: Lung screening leaves no lasting harm
August 17, 2016 -- Fear can lead to avoidance of lung cancer screening, but a welcome boost has come from a new study analyzing the long-term effects of low-dose CT examinations in the U.K. Lung Cancer Screening trial. It found that patients randomized to the imaging arm did not experience unnecessary long-term anxiety.
3D imaging helps diagnose 1.7-million-year-old cancer
August 11, 2016 -- Cancer is often thought to be a product of modern times and lifestyles, but researchers have discovered what they believe is the earliest case of malignancy -- in a fossil from an early human ancestor who lived about 1.7 million years ago. The key to diagnosing this ancient cancer was advanced 3D imaging technology.
7 top tips for reporting cervical spine CT
August 9, 2016 -- To help eliminate mistakes by radiology trainees reporting out-of-hours cervical spine trauma CT scans, it's crucial to bear in mind seven key learning points, U.K. researchers reported at the 2016 congress of the European Society of Musculoskeletal Radiology.
Rio 2016 polyclinic opens its doors
August 3, 2016 -- The Rio Olympics begin on Friday. Two MRI systems, plus three digital x-ray and four ultrasound units, will be housed in the 3,500-sq-m polyclinic, which stays open until 18 September. We take a peep inside the building.
Medical physics: Future directions and current status
July 29, 2016 -- Where is medical physics now, and where might it be in 60 years' time? And what have been the key moments in the evolution of medical physics? These questions were addressed in a symposium at London's Imperial College.
Interventional radiology from head to toe
July 27, 2016 -- Interventional radiologists are like strikers in a football match: Both depend on other players passing the ball to them, says Dr. Christian Stroszczynski, the new head of the German Society for Interventional Radiology and Minimally Invasive Therapy. In this interview, he reveals his aims during his term in office.
