AI can prescreen head CT studies for urgent findings
October 16, 2018 -- A set of artificial intelligence (AI) algorithms can prescreen head CT scans for urgent findings such as intracranial hemorrhage and cranial fracture, enabling triage of these cases for priority review by radiologists, according to research published online on October 11 in the Lancet.  Discuss
PET/CT rivals CT for NSCLC recurrence
October 11, 2018 -- Swiss researchers have found that FDG-PET/CT is "not superior" to contrast-enhanced CT in the detection and evaluation of non-small cell lung cancer (NSCLC) recurrence two years after follow-up curative treatment. Their study was published online on 4 October in the Annals of Thoracic Surgery.  Discuss
Dutch develop novel 3D method to track central airways
October 5, 2018 -- A group from Amsterdam has examined conebeam CT projections of a 3D-printed thorax phantom and used prototype software for template generation, template matching, and triangulation to determine bronchus motion. They think markerless 3D monitoring can help in radiotherapy.  Discuss
Survey: Clinicians still lack dose awareness
October 3, 2018 -- Over a third of clinicians have received no formal education on the risks of exposure to ionizing radiation from imaging examinations, and more than a quarter believe the impact of dose on lifetime cancer risk is either very small or negligible, a new U.K. survey has found.  Discuss
Tomosynthesis provides boost in painful prosthetic cases
October 2, 2018 -- French researchers have revealed that digital tomosynthesis has a similar diagnostic performance to x-ray for diagnosing prosthetic loosening after total hip arthroplasty, but it yields better interobserver agreement. They compared the performance of tomosynthesis with that of x-ray and also CT with metal artifact reduction.  Discuss
Augmented reality guides screw placement in spinal surgery
October 1, 2018 -- Researchers from Sweden have used augmented reality navigation technology to overlay 3D conebeam CT scans onto a real-time video of patients undergoing spinal surgery, according to a recent article in Spine. The technique improved the accuracy of implanting pedicle screws in these patients.  Discuss
NELSON gives Europeans go-ahead for CT lung screening
September 27, 2018 -- CT lung cancer screening got a big boost this week from researchers in the Dutch-Belgian Randomized Lung Cancer Screening (NELSON) trial, who at the 2018 World Conference on Lung Cancer in Toronto reported a 26% mortality reduction for men in the trial. The findings could give the green light to CT lung screening in Europe.  Discuss
Parizel quits Europe, heads Down Under
September 26, 2018 -- One of the best-known European radiologists, Dr. Paul M. Parizel, PhD, is to leave his post at Antwerp University Hospital in Belgium. From January, he will combine an academic position as a full professor at the University of Western Australia with a part-time appointment at Royal Perth Hospital.  Discuss
Dutch give fresh impetus to postmortem imaging
September 25, 2018 -- A new Dutch study has shown minimally invasive autopsy performs as well as traditional autopsy in the clinical setting -- and in some cases even better. Also, the research revealed unexpected findings in 1 in 5 postmortem patients, underlining the continuing need for autopsy.  Discuss
Coronary CT angio makes giant leap in dose reduction
September 17, 2018 -- A large international survey of radiation dose has demonstrated a huge reduction of radiation exposure in coronary CT angiography over the last decade. The study has shown doctors have reduced radiation exposure while maintaining image quality.  Discuss
