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.
Imaging detects telltale signs of Zika infection August 25, 2016 -- Radiologists reviewing medical imaging scans of babies and fetuses in cases of suspected Zika infection can expect to see a number of telltale brain abnormalities, including loss of gray- and white-matter volume and a "collapsed" appearance of the skull. That's according to a report on the devastating virus published August 23 in Radiology.
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.
Deconstructed PACS: It's not all bad news August 24, 2016 -- Next time an enterprise IT vendor asks you at a tradeshow if you want to deconstruct your PACS, interface your workflow, free your data, and enable enterprise interoperability, it might be worth sticking around, writes industry expert Stephen Holloway in his latest column.
4D flow MRI shows smallest hint of LV dysfunction August 23, 2016 -- Four-dimensional flow MRI can depict even subtle changes in left ventricular (LV) function, bringing new insight to the diagnosis of patients with mild left ventricular dysfunction and remodeling, concludes a study published on 17 August in PLOS One.
Ratib: Open-source software boosts image management August 22, 2016 -- Open-source software can be an effective way to facilitate image interpretation, archiving, and distribution, particularly in developing countries that lack the IT infrastructure and cash to adopt digital image management, according to Dr. Osman Ratib of the University Hospital of Geneva.
Navigation tool permits biopsies in closed MRI scanners August 22, 2016 -- A new investigational technique is enabling German researchers to perform MR-guided liver biopsies of lesions that can't be seen using other modalities and are inaccessible in most MRI scanners, according to a new study in the August edition of European Radiology.
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.
