Fewer lung cancer patients meet CT lung screening criteria
February 27, 2015 -- It's the ultimate irony: The success of public health efforts to get people to stop smoking is resulting in fewer individuals being eligible for CT lung cancer screening. In fact, some people are continuing to smoke just to be eligible for CT scans, according to new research in the Journal of the American Medical Association.
Vertebral CAD aces detection of compression fractures
February 26, 2015 -- A new computer-aided detection (CAD) scheme can robustly detect vertebral compression fractures on spine CT images. The algorithm was developed by a team led by Dr. Ronald Summers, PhD, from the U.S. National Institutes of Health.
CT scanner in the ED cuts patient waiting times
February 20, 2015 -- Substantial time can be saved by siting CT scanners in the emergency department (ED) rather than transporting patients to the radiology department hundreds of meters away, according to a new study in the Journal of the American College of Radiology.
Results of European CT screening trial can be widely applied
February 19, 2015 -- Individuals scanned with CT in the Nederlands-Leuvens Longkanker Screenings Onderzoek (NELSON) lung cancer screening trial had a similar risk of cancer as people who did not participate in the study, meaning the research can be generalized to a wider population.
CMS data show wide variations in CT, MR use across U.S.
February 18, 2015 -- Newly available data from the U.S. Centers for Medicare and Medicaid Services (CMS) show that wide variations in the use of brain CT and lumbar MR imaging exist across the U.S., according to a study published online in Radiology. The findings could help policymakers tailor interventions to curb overuse among providers.
Mobile stroke unit with CT scanner speeds care in Cleveland
February 12, 2015 -- A mobile stroke treatment unit with a CT scanner and medical personnel aboard is dramatically cutting time-to-treatment decisions for Cleveland stroke patients. Clot-busting drugs were provided in nearly half the usual time, according to a study presented at this week's 2015 International Stroke Conference.
Koning positions breast CT scanner as 1-stop diagnostic shop
February 11, 2015 -- With approval from the U.S. Food and Drug Administration now in hand for its breast CT scanner, Koning plans to market the 3D system as the ultimate one-stop diagnostic workup tool. Breast screening applications will have to wait, however, pending further study.
Lung-RADS cuts false positives in CT lung screening -- at a price
February 10, 2015 -- The Lung-RADS classification system for dealing with suspicious findings on CT lung cancer screening exams may be a double-edged sword, reducing false positives but also sensitivity, according to a new study published February 10 in the Annals of Internal Medicine.
Primary care providers slow to order CT lung cancer screening
February 9, 2015 -- Primary care providers are often unaware of current guidelines on CT lung cancer screening, and they are ordering few scans for their patients at risk, according to a new survey in Cancer Epidemiology, Biomarkers and Prevention. Countering this trend is key if CT screening is to reduce lung cancer mortality.
