New audit pinpoints causes of 'wasteful' unnecessary scans
May 17, 2017 -- Radiologists' failure to check the validity of requests for CT and MRI scans, along with ignorance among referring doctors of appropriateness criteria for imaging examinations, are the most important reasons for costly inappropriate requests of radiological exams, a new study from Saudi Arabia found.
Why all the fuss about artificial intelligence?
May 10, 2017 -- There's been a lot of talk recently about artificial intelligence in radiology. The question on everybody's mind is: "Will artificial intelligence replace radiologists?" Imaging informatics columnist Dr. Neelam Dugar is convinced it will add value by making radiologists smarter and better diagnosticians.
German experts assess impact of new radiation law
May 9, 2017 -- Radiation protection and cancer imaging feature prominently on the agenda for the 98th German Radiology Congress, which takes place in Leipzig from 24 to 27 May. As part of our buildup to the conference, we have interviews on these two topics.
CAD, 3D rendering give boost to surgical planning
May 8, 2017 -- Virtual simulations of interventional and surgical procedures using open-source computer-aided detection (CAD) software is improving the accuracy of preoperative planning in corrective jaw surgery, German researchers have found.
Women may need less frequent CT lung cancer screening
May 2, 2017 -- Women may need less frequent CT lung cancer screening than men, according to a study to be presented on 6 May at the European Lung Cancer Conference in Geneva. The finding could enable physicians to reduce CT screening frequency (and thus exposure to radiation) in women.
Photon-counting breast CT shows promise
May 1, 2017 -- Tests of a prototype photon-counting detector breast CT scanner show that the system could be useful as an adjunct to low-dose breast CT by separating the energy levels of different types of materials within the breast to assess tissue composition and improve cancer diagnosis.
Radiology mourns Dr. Helen Carty, 1944-2017
April 28, 2017 -- Tributes are being paid to Dr. Helen Carty, the leading pediatric radiologist from Liverpool, U.K., who died peacefully at home on 23 April at the age of 72. She was a world expert in imaging of child abuse, the president of ECR 2004, and a gold medalist at ECR 2009.
Dutch present strategic vision for 2020
April 28, 2017 -- The Radiological Society of the Netherlands has devised a roadmap to help reach its main goals for the future. Dr. Hildo Lamb provides the background to the project and explains why information technology and multidisciplinary cooperation both will have a crucial role to play.
Lung-RADS category 4X helps diagnose lung cancer
April 27, 2017 -- The addition of category 4X lesions in the Lung CT Screening Reporting and Data System (Lung-RADS) imaging scheme adds value and increases malignancy yields among experienced radiologists, according to a Dutch study in Radiology. The 4X nodules turn out to be malignant in half of cases.
Low doses can make DSCT cardiac perfusion routine
April 25, 2017 -- The latest generation dual-source CT (DSCT) scanner cuts the radiation dose of cardiac CT perfusion enough to make it suitable for daily practice, according to new research. Expanded z-axis coverage and better signal-to-noise ratios can offer more information on myocardial blood flow.
