Autosegmentation of head and neck CT aids treatment planning
August 25, 2014 -- Dutch researchers looked into automated segmentation of head and neck CT for treatment planning, and found it fast and accurate enough for daily clinical use -- dozens of times faster, in fact, than the manual technique it aims to replace.
Specialist certification gets easier in Germany
August 22, 2014 -- Changes to the training system are having major implications for radiologists in Germany. In this interview, Dr. Reinhard Loose, PhD, head of the Radiological Protection Commission Working Group of the German Radiological Society, discusses the certification requirements introduced in summer 2012.
Conebeam CT pinpoints tricky scaphoid fractures
August 20, 2014 -- Conebeam CT is a highly effective, low-dose technique for detecting scaphoid fractures, and can demonstrate concomitant fractures that are notoriously difficult to see on radiographs, according to a prize-winning Belgian study presented at Europe's leading musculoskeletal congress.
U.K. group issues report on CT radiation dose
August 18, 2014 -- A U.K. government group has issued a report on CT radiation dose that documents the population's rising exposure to medical radiation, and makes recommendations for reducing the cancer risk from that exposure.
Interventional radiologists need to follow shielding protocols
August 15, 2014 -- Patients must be protected from unnecessary radiation exposure, but what about radiologists who perform interventional exams, particularly CT-guided procedures? German researchers found that radiologists have a low risk of overexposure -- if appropriate precautions are taken.
EJR: Everything you need to know about CT dose
August 12, 2014 -- All healthcare staff have a responsibility to avoid unnecessarily high radiation dose, but the key players remain diagnostic radiologists who can and should integrate the necessary information and decide upon scan protocols, according to an article published by European Journal of Radiology.
Lung CAD scheme aces preliminary test
August 11, 2014 -- A newly revamped lung computer-aided detection (CAD) algorithm has shown outstanding accuracy in a study of lung lesions from a database and generated few false positives, according to a study published online on 24 July by European Radiology.
CT proves value for pulmonary embolism in pregnancy
August 7, 2014 -- A relatively large U.K. study has provided fresh evidence that CT pulmonary angiograms result in positive outcomes when diagnosing pulmonary embolism in pregnant women, for whom the incidence of venous thromboembolism is four times greater than in the nonpregnant population.
ICR 2014 organizers use new tactics to lure 5K delegates
August 6, 2014 -- For the first time in its almost 90-year history, the International Congress of Radiology (ICR) will benefit from a fully integrated scientific program with global participation in every session, according to the event organizers. An estimated 5,000 delegates are expected at ICR 2014, to be held in Dubai in September.
Radiology interpretation performance may slip late in sessions
July 30, 2014 -- Radiologists may take less time to interpret images and see changes in their performance over the course of a long reading session, according to analysis from Warwick, U.K. But it's not clear if that dynamic represents an actual clinical concern or merely effects attributable to the study designs.
U.K. team scoops top prize for chest wall deformities study
July 24, 2014 -- Developing a keen awareness of the radiological features of congenital chest wall deformities is a useful clinical skill, and imaging can also illustrate pre- and postsurgical appearances for more conditions requiring surgical correction, according to award-winning research from a top facility in London.
Scots get set for Usain Bolt, Mo Farah, et al
July 23, 2014 -- The Commonwealth Games begin today and is the largest sporting event ever held in Scotland. Musculoskeletal radiologist Dr. David Ritchie and his team of volunteers are prepared for everything and have already been keeping busy in the state-of-the-art polyclinic in Glasgow.
New-generation dual-source CT heart scans prove fast and sharp
July 22, 2014 -- Operating the new third-generation dual-source CT scanner 24/7 has revealed a rapid system with robust imaging capabilities and an array of new features to perform heart scans at low doses, according to researchers from a leading German facility.
'Tiered' CT approach shows promise in coronary disease
July 22, 2014 -- In patients with stable angina and suspected coronary disease, a "tiered" approach to CT imaging finds -- so far at least -- that calcium scoring is all many patients need. That's right, for most patients there's simply no need to start with the big imaging guns, researchers in Rotterdam report.
4D peripheral CT often beats dynamic MRI
July 21, 2014 -- Pinpointing flow problems in the peripheral arteries is a task that is typically handed over to dynamic MR angiography. But often, bone-subtracted 4D CT angiography can do a better job, according to German researchers.
Rotterdam group helps gauge coronary disease severity
July 14, 2014 -- At the same time that a validated fractional flow reserve CT angiography application seems to be nearing U.S. Food and Drug administration approval, a new contender for gauging the severity of coronary disease at CT is pushing its way into the ring. Furthermore, it promises to be a simpler solution, according to a team of Dutch researchers.
