Lead protects pacemakers from radiation January 15, 2016 -- Lead shields provide a simple and inexpensive way to reduce radiation delivered to pacemakers during radiation therapy, according to a new study. The protection is modest in many instances, but can in some cases reduce radiation by 40%, cutting the risk of pacemaker failure.
PACS software benefits from real-world feedback January 14, 2016 -- Radiologists frequently discover usability issues on workstations during clinical use, so it's important for vendors to continue evaluating their software after deployment, according to new research from the University Medical Center Groningen in the Netherlands.
Functional MRI algorithm maps brain function January 14, 2016 -- An algorithm that generates reproducible, personalized maps of neural networks in the brain using functional MRI has been demonstrated by an international collaboration. The noninvasive approach could enable more efficient planning of neurosurgery for brain tumors and disorders such as epilepsy.
Social media 'minefield' requires extreme care January 13, 2016 -- Social media is a minefield for unwary medical professionals, and it's vital to be fully aware of your local guidance, particularly on anonymization of images and consent issues, a group of U.K. radiologists warned at RSNA 2015 in Chicago.
Analysis finds variation in how radiologists use PACS January 12, 2016 -- Individual radiologists may not always go about interpreting an imaging study in the same manner on PACS as their colleagues, but these variations don't typically result in differences in reading times, according to research presented at the recent RSNA 2015 meeting in Chicago.
MR-Eye work scoops top prize at RSNA 2015 January 11, 2016 -- A pioneering exhibit about the role of microscopy coil MRI for the assessment of the orbit and periorbital structures led to a U.K.-Australian team collecting a prestigious Magna Cum Laude award at last month's RSNA 2015 meeting in Chicago.
Global survey puts renewed emphasis on dose January 8, 2016 -- European hospitals perform nuclear cardiology at lower doses than the rest of the world, and they use more of the best practices that have been identified, according to the results of a global survey published in the European Journal of Nuclear Medicine and Molecular Imaging.
Automated technique compares lung screening priors January 7, 2016 -- A new technique uses digital subtraction imaging to detect temporal changes in lung cancer screening scans between baseline and follow-up. The method could make screening follow-up easier by quickly identifying new or growing nodules.
CTC excels in matchup with FIT, colonoscopy January 6, 2016 -- In the first randomized trial to pit CT colonography (CTC) against the fecal immunochemical test (FIT) and conventional optical colonoscopy, FIT yielded a higher participation rate than CTC but found fewer cancers and advanced lesions, according to results published in the Journal of the National Cancer Institute.
CT breaks new ground in assessing heart valves January 5, 2016 -- Third-generation dual-source CT scanners can now provide fast, comprehensive, and complementary information in the evaluation of mechanical heart valves, award-winning Dutch researchers reported at last month's RSNA meeting in Chicago.
