Article blasts LNT theory of radiation harm February 5, 2016 -- An article in the American Journal of Clinical Oncology calls for the abandonment of the linear no-threshold (LNT) model, which holds that even low levels of radiation -- similar to those used in medical imaging -- can be harmful.
Extracolonic findings on CTC are rare but often important February 1, 2016 -- Extracolonic findings are relatively uncommon in CT colonography (CTC) screening, but the few that require follow-up tend to be highly significant to the patient's health, according to a new report in the American Journal of Roentgenology.
More former smokers should get CT lung screening January 28, 2016 -- Low-dose CT lung cancer screening should be expanded to include smokers who gave up the habit long ago, concludes a new study published in the February issue of the Journal of Thoracic Oncology.
Colorectal cancer patients diagnosed younger than screening age January 25, 2016 -- Many colorectal cancer patients are being diagnosed when they are younger than 50 years old, the age at which most guidelines say screening should begin, according to a new analysis of U.S. patients in Cancer. The findings raise questions about how -- and whether -- screening should be addressed in younger adults.
Societies issue imaging guidelines for chest pain January 22, 2016 -- New guidelines for the appropriate use of diagnostic imaging for chest pain have been released by the American College of Cardiology, the American College of Radiology, and several other societies, according to a report published online January 22 in the Journal of the American College of Cardiology and the Journal of the American College of Radiology.
Study finds CT use has doubled for minor injuries January 19, 2016 -- The use of CT for minor injuries has doubled in the past decade, according to a study of more than 8.5 million California patients in the Journal of Surgical Research. The increase may indicate that it's time to redouble efforts to ensure that radiation is used appropriately.
Emphysema-related COPD on CT signals higher malignancy risk January 18, 2016 -- Individuals who have certain types of emphysema may also be at higher risk of cancer if they have suspicious nodules found on CT lung cancer screening scans, according to new research. The findings could help researchers better determine which suspicious nodules warrant further workup.
