Integrated circuit detector cuts noise, dose in CTC
April 23, 2014 -- More efficient detector circuitry can reduce image noise in CT colonography (CTC) images by about 10% -- or, alternatively, reduce radiation dose by about 20% if noise levels were to remain unchanged -- according to a study of nearly 400 individuals.
Commentary: Coronary CT angiography doses must be public
April 21, 2014 -- It's high time to start down the path to radiation dose transparency for coronary CT angiography -- as a mark of service quality, according to a hard-hitting guest editorial by a top U.K. cardiac imaging specialist writing in the British Journal of Radiology.
Swedish project helps uncover secrets of ancient Egypt
April 16, 2014 -- Visualization experts and radiologists from Sweden are contributing to a pioneering project designed to shed new light on ancient Egyptian mummies and improve education of museum visitors. The team behind the project shares their experiences and give tips on how to get the best results.
Profile of medical physicists looks set to rise sharply
April 15, 2014 -- The new European Union directive on the safety of ionizing radiation in medicine requires closer involvement of medical physics experts in radiology. This interview with Dr. Horst Lenzen discusses how this requirement can be met without placing excessive demands upon hospitals.
Think deeply to cut out mistakes, urge Dutch prizewinners
April 9, 2014 -- Beware the dangers of intuitive thinking. That's the central message of new award-winning research from the Netherlands about cognitive errors, which includes 20 practical tips on how to avoid typical mistakes.
Proton CT can improve stopping power accuracy
April 7, 2014 -- The fine-tuning of proton therapy plans to maximize tumor dose and minimize dose to healthy tissue is held back by significant uncertainties in the stopping power estimates used to calculate proton range. Danish researchers have boosted the accuracy of these estimates with an image reconstruction technique combining x-ray cone-beam CT data with a proton CT scan.
3D planning proves value in facial reconstructions
April 4, 2014 -- Facial reconstructive surgery appears to have turned a corner, judging by a recent case in the U.K. that would have challenged even the most experienced and skilled surgeon. A patient's face was rebuilt after a horrific motorbike accident, and 3D visualization techniques made the difference.
U.K. issues new guidance on cancer imaging
April 1, 2014 -- The U.K. Royal College of Radiologists (RCR) has published updated recommendations for cross-sectional imaging in cancer management. They can be downloaded free of charge from the RCR's website.
Mobile application brings images into autopsy room
March 31, 2014 -- Mobile devices can be used as an effective tool to link a radiology department and a forensic pathology institute at two different locations with a common workflow, enabling forensic pathologists to view CT images and reports offline during autopsies, German researchers have found.
Swedish radiologist wins award for 3D dual-energy CT image
March 31, 2014 -- A Swedish researcher has received the top prize in a prestigious image competition for his 3D dual-energy CT scan of a patient who received a mechanical heart pump while waiting for a heart transplant.
CT perfusion useful for evaluating small esophageal tumors
March 21, 2014 -- CT perfusion can be used to evaluate esophageal cancers with small tumor diameters that are not amenable to assessment with PET/CT, according to a new study by Turkish researchers presented at ECR 2014 earlier this month.
Making the invisible, visible: Meeting EU requirements on dose
March 20, 2014 -- Implementing an effective dose management system will help hospitals meet the new European Union legislative requirements and enable radiologists to meet their ethical responsibility to maximize patient safety, writes Dr. Jan Casselman.
CT's golden days are gone, as focus shifts to cost cutting
March 18, 2014 -- The worst of the pain in the CT sector appears to be over, and the modality has emerged smarter, leaner, and more efficient, but this in no way signals another golden era of booming sales. The next five years will see more consolidation and stringent management of advanced imaging resources.
Heart rate jumps with CT contrast agent
March 10, 2014 -- VIENNA - Faster heart rates are the last thing radiologists want with coronary CT angiography. But that's apparently what they get when using a contrast agent with a slightly higher iodine concentration, according to a Monday presentation at ECR 2014.
Study finds PET/CT can help diagnose CUP syndrome
March 10, 2014 -- VIENNA - FDG-PET/CT can identify a possible primary tumor in patients with carcinoma with unknown primary tumor (CUP) syndrome at a rate comparable to that found in autopsy studies, German researchers reported on Monday at ECR 2014.
CT saddled as 'workhorse' for evaluating post-op complications
March 10, 2014 -- VIENNA - For suspected late postoperative complications in the abdomen, CT can provide swift and accurate diagnoses in what may be life and death situations, ECR 2014 delegates heard at Sunday's session on gastrointestinal tract imaging.
