3D-printed blood vessels reproduce patient clots
August 17, 2017 -- Dutch researchers have created a blood-vessel model that effectively replicates the formation of a blood clot caused by stenosis defects. The team developed a microfluidic blood-vessel model using layered stacks of CT angiography data combined with sterolithography, a light-based 3D-printing process.  Discuss
CT CAC scoring tops age for predicting heart disease risk
August 4, 2017 -- Is age just a number? Maybe, at least for predicting atherosclerotic cardiovascular disease events in older adults. Coronary artery calcium (CAC) scoring with CT is better than a patient's age for predicting risk -- particularly for coronary heart disease, according to research published online on July 26.  Discuss
How to optimize dose in hybrid operating rooms
August 2, 2017 -- A clinical team from Liverpool, U.K., has revealed a 14-point strategy for improving radiation dose awareness and protection in a hybrid operating room. The checklist could serve as a useful guide for hospitals across Europe and beyond performing image-guided minimally invasive procedures.  Discuss
Zurich team moves ahead on heart replacements
July 28, 2017 -- A Swiss group has developed a soft 3D-printed silicone heart that beats almost like a human heart. The technique, which uses CT images of a real patient to create a computer-aided design model in 3D, could provide tailor-made, soft artificial hearts in the future.  Discuss
Low CT productivity from 8 to 9 a.m. needs attention
July 25, 2017 -- There's plenty of slack in imaging departments at the start of the working day and also on Fridays. That's the main finding of a detailed analysis of CT productivity at a large university hospital, but simple changes in staffing and workflow practices can lead to major improvements.  Discuss
Radiomics helps predict NSCLC treatment outcome
July 17, 2017 -- A CT-based prognostic radiomic signature for non-small cell lung cancer can be ported for use with cone-beam CT images, according to a new study. The approach could potentially allow treatments to be monitored and adjusted in their early stages to afford better outcomes for patients, noted the researchers from the Netherlands.  Discuss
New CT technique identifies blood vessel plaque
July 13, 2017 -- A new CT technique can measure blood vessel inflammation, allowing doctors to identify and treat patients at risk for cardiovascular disease, according to a U.K. study published online 12 July in Science Translational Medicine.  Discuss
Multipurpose CT lung cancer screening more cost-effective
July 6, 2017 -- CT lung cancer screening is likely to be more cost-effective if it is used to identify other tobacco-related conditions in high-risk people, according to a study published in the Journal of Thoracic Oncology.  Discuss
Egypt releases DRLs but dose concerns remain
June 30, 2017 -- Egypt has unveiled the first national diagnostic reference levels (DRLs) for CT, but senior radiologists still have concerns about radiation dose. Areas for improvement include the selection of exposure parameters for different examinations, taking into account the image quality, with particular attention on facilities using consistently higher doses compared with DRLs.  Discuss
French group announces 9-point plan of action
June 29, 2017 -- France's national union of private radiologists (Fédération Nationale des Médecins Radiologues, FNMR) unveiled its new independent medical imaging project. The plan lists nine major areas on which urgent action is necessary, said FMNR President Dr. Jean-Philippe Masson.  Discuss
