Phase-contrast CT captures microscopic details of mummy
September 25, 2018 -- What can today's radiology professionals learn from CT scans of the ancient past? Plenty, according to Swedish researchers, who used a technique called phase-contrast CT to reveal micron-sized details in a mummified hand and published their findings online September 25 in Radiology.  Discuss
Imaging-based autopsy matches traditional approach
September 25, 2018 -- Rates of autopsy are declining, for a variety of cultural and economic reasons. But autopsy still offers valuable information about an individual's cause of death. Could an imaging-based approach replace traditional autopsy? Dutch researchers investigated this question in a study published September 25 in Radiology.  Discuss
CT decision aid cuts follow-up imaging in kids with trauma
September 21, 2018 -- Shared decision-making using a decision aid did not reduce the use of head CT for children with minor head injury, but it did improve parental knowledge and engagement and ultimately decrease downstream imaging, according to an article published online September 21 in JAMA Network Open.  Discuss
ISCT: Machine-learning FFR-CT expedites heart evaluation
September 19, 2018 -- Machine-learning fractional flow reserve CT (FFR-CT) may help clinicians overcome key barriers to conventional FFR-CT, including the lengthy amount of time required to obtain measurements, according to a presentation at the 2018 International Society for Computed Tomography (ISCT) symposium.  Discuss
ISCT: 5 ways DECT can improve the value of imaging
September 17, 2018 -- SAN DIEGO - What are the top clinical applications of dual-energy CT (DECT), and in what ways does the technique add value to diagnostic imaging? Radiologists from Stanford and Duke University tackled these and similar questions in a session at the 2018 International Society for Computed Tomography (ISCT) symposium.  Discuss
ISCT: Should CT be first for evaluating chest trauma?
September 14, 2018 -- SAN DIEGO - What's the best first-line diagnostic technique for assessing penetrating chest trauma? Dr. Savvas Nicolaou made the case for CT as the imaging modality of choice in a Friday presentation at the 2018 International Society for Computed Tomography (ISCT) symposium.  Discuss
3 CTA signs show which stroke patients can skip surgery
September 13, 2018 -- There are three key characteristics evident on CT angiography (CTA) scans that show clot-busting drugs are working to restore blood flow in stroke patients, according to a September 11 article in the Journal of the American Medical Association. These patients can thus avoid referral for surgical clot removal.  Discuss
Deep learning can accurately stage liver fibrosis on CT
September 7, 2018 -- Deep-learning software can accurately stage liver fibrosis on contrast-enhanced CT studies, according to an article published online September 4 in Radiology. In a new study from South Korea, the software outperformed four radiologists as well as two serum fibrosis markers calculated from laboratory tests.  Discuss
Access to CT lung screening varies by population density
September 7, 2018 -- Smokers in densely populated regions in the U.S. live significantly closer to a CT lung cancer screening facility than those residing in more sparsely populated areas, according to an article published online September 1 in the Journal of the American College of Radiology.  Discuss
High rate of pediatric head CT persists despite efforts
September 5, 2018 -- U.S. emergency departments continue to rely on CT to routinely evaluate children presenting with head trauma, despite long-standing efforts -- such as the Image Gently initiative -- to reduce overuse of the exam, according to an article published online September 4 in Pediatrics.  Discuss
