CT radiomics improves management of bile duct cancer
October 19, 2018 -- Researchers from China have developed a radiomics model that can determine the malignancy of lymph node metastases in patients with bile duct cancer by analyzing features on CT scans, according to an article recently published online in Radiology. They believe the model can predict the survival rate of patients.  Discuss
Cinematic rendering enhances ovarian cancer evaluation
October 12, 2018 -- The photorealistic detail provided by cinematically rendered CT scans helped researchers from China characterize and stage ovarian tumors better than they could with traditional volume rendering and multiplanar reconstruction, according to an article published online in the Journal of Ovarian Research.  Discuss
Report predicts plunge in U.S. lung cancer mortality
October 9, 2018 -- In a new paper, researchers from the U.S. National Cancer Institute and other U.S. institutions predict mortality from lung cancer will plunge through 2065, largely due to the success of smoking-control efforts. Lung cancer screening may also help reinforce this trend, according to the article, published online October 8 in the Annals of Internal Medicine.  Discuss
CT lung cancer screening foiled by low adherence
October 8, 2018 -- More than 20% of U.S. military veterans who had a negative baseline CT lung cancer screening exam did not return for their follow-up exam, according to a study presented at the 2018 American College of Chest Physicians meeting in San Antonio.  Discuss
EPA proposal may lead to looser radiation regulations
October 4, 2018 -- The U.S. Environmental Protection Agency (EPA) has proposed a rule change that could pave the way for less-stringent regulations limiting population-level radiation exposure, including from medical imaging, according to an October 2 report from the Associated Press.  Discuss
New decision aids may revamp CT lung cancer screening
October 4, 2018 -- Are current decision aids used to guide CT lung cancer screening biased against the exam? A proponent for lung screening has developed two new decision aids that he believes more accurately reflect the benefits and harms of the exam -- and could boost screening uptake in eligible individuals.  Discuss
Calcium scores on CT colonography predict cardiac events
October 2, 2018 -- In another side benefit to CT colonography screening, researchers have discovered that the technique can measure abdominal aortic calcification, which could be more effective than traditional measures for estimating a person's risk of heart attack, death, and other cardiovascular events, according to an October 2 article in Radiology.  Discuss
CT lung screening reduces cancer mortality in men by 26%
September 27, 2018 -- New results from the Dutch-Belgian Randomized Lung Cancer Screening (NELSON) trial have reaffirmed that CT lung cancer screening can significantly reduce mortality for high-risk smokers, producing a 26% mortality reduction in men, according to a Tuesday presentation at the 2018 World Conference on Lung Cancer in Toronto.  Discuss
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
