Can local use guidelines reduce inappropriate imaging?
November 12, 2018 -- Imaging utilization rules based on national guidelines may not cover all clinical circumstances. Appropriate use criteria based on local best practices can fill this gap, however, and help avoid inappropriate imaging, according to research published online November 7 in the American Journal of Roentgenology.  Discuss
CT tumor evaluation criteria may need to be reworked
November 9, 2018 -- Current guidelines used to determine the effect of cancer treatment on metastatic tumors often yield inconsistent results, say researchers from Germany, who uncovered notable differences in tumor selection on CT among radiologists. Their findings were published online November 6 in Radiology.  Discuss
IASLC advocates CT lung cancer screening
October 26, 2018 -- The International Association for the Study of Lung Cancer (IASLC) has emphasized again its support for CT lung cancer screening as a tool for identifying early-stage lung cancer and reducing the mortality rate of high-risk smokers.  Discuss
CT reveals heart enlargement differs in men, women
October 25, 2018 -- Is CT a viable alternative to cardiac MRI for assessing heart chamber enlargement? Yes, say researchers from Canada, who discovered that the condition was much more common in men than women. Their findings were published in the November issue of the American Journal of Roentgenology.  Discuss
Machine-learning CCTA helps characterize heart plaques
October 24, 2018 -- Researchers from Japan have developed a method that uses machine learning to characterize plaques on coronary CT angiography (CCTA) scans with an accuracy exceeding that of standard techniques, according to an article published online October 20 in the Journal of Cardiovascular Computed Tomography.  Discuss
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
Special Feature
Ultrahigh-resolution CT enhances image quality twofold

A new ultrahigh-resolution CT scanner -- boasting two times the spatial resolution of conventional CT -- significantly enhanced the image quality of in-stent restenosis in blood vessel phantoms without altering radiation dose. Read more
