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.
1,000th scan performed at Rio 2016 polyclinic August 17, 2016 -- As the Olympic flame continues to burn brightly in Rio, the 1,000th imaging exam was performed at the Olympics yesterday. An impressive 610 MRI scans were carried out on the first 12 days of the games, surpassing the total number completed throughout London 2012.
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.
New neural network outperforms CAD for mammography August 16, 2016 -- A convolutional neural network trained on a large dataset of mammographic lesions outperformed a conventional mammography computer-aided detection (CAD) scheme, according to a new Dutch study published this month. These networks can be fine-tuned based on radiologists' knowledge.
Newspeak in radiology August 15, 2016 -- Do radiologists communicate with themselves and their colleagues in such a way that everybody gets the same message? Perhaps not. New nomenclature gets coined by some ignoramuses that is plainly wrong, the Maverinck contends. Read more about his thoughts on language in this latest column.
Mammography in Malta: Room for improvement August 12, 2016 -- How well is mammography performed in Malta? No one knows for sure because image-quality studies haven't been conducted -- until now. New research found that the average reject rate for the nation fell within acceptable levels, but there is still room for improvement, particularly at individual centers.
