Study: CT screening would cut lung cancer deaths in China
July 25, 2017 -- Using a statistical model, Chinese researchers found that CT screening could reduce deaths from lung cancer in China by 24% compared with no screening, mostly by reducing deaths among smokers, according to a paper published July 14 in the Chinese Journal of Cancer.
8 strategies to optimize radiation dose in CT
July 14, 2017 -- How can imaging providers optimize CT dose to maximize the risk-benefit ratio and deliver better patient care? In this article, Priscilla Butler from the American College of Radiology offers eight actionable strategies for managing radiation dose while still providing diagnostic quality and accuracy.
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.
Insurance coverage for CTC boosts screening
July 11, 2017 -- Patients who have insurance coverage for CT colonography (CTC), also known as virtual colonoscopy, are much more likely to receive any form of colorectal cancer screening -- even a different screening test such as colonoscopy, according to research published online July 11 in Radiology.
Multipurpose CT lung cancer screening more cost-effective
July 3, 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.
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.
Subsolid lung nodule assessment with CT evolves
June 28, 2017 -- As their experience with subsolid nodules at CT grows, radiologists are learning more about their characteristics and potential risk of malignancy. Overall, the past several years have seen nodule size and growth rise in importance relative to CT density, a less reliable predictor of malignancy.
Is postmortem imaging acceptable to Muslims?
June 27, 2017 -- Muslims living in both Europe and the Middle East prefer postmortem imaging over conventional autopsy, believing it preserves the dignity of the corpse, but they prefer autopsy in cases of homicide or suicide, new research has found.
Fujitsu develops AI to analyze CT studies
June 27, 2017 -- Fujitsu Laboratories has unveiled artificial intelligence (AI)-based technology that can find and retrieve CT studies of patients who have similar diseases.
AI can yield patient-specific radiation dose estimates
June 22, 2017 -- A machine-learning algorithm shows potential for facilitating the holy grail of real-time, patient-specific radiation dose estimates from CT scans, according to research presented at the Society for Imaging Informatics in Medicine annual meeting earlier this month in Pittsburgh.
