Nonsolid lung nodules found on CT screening harbor few cancers December 18, 2014 -- Nonsolid nodules detected with CT lung cancer screening are often indolent, and even when they do harbor cancer, the long lead times before such nodules develop make it safe to follow them up less often, according to new long-term data presented at the RSNA 2014 meeting.
CT ties emphysema to mortality, independent of other risks December 15, 2014 -- CT scans show that people with emphysema are at risk of earlier death than those without the disease, even if they have no evidence of chronic obstructive pulmonary disease or airflow obstruction, according to a study published on Monday in the Annals of Internal Medicine.
Top 5 trends from RSNA 2014 in Chicago December 11, 2014 -- With RSNA 2014 in the books, now is a good time to look back on the Chicago meeting to identify the major trends affecting radiology. Top stories circulating the halls of McCormick Place included the meeting's 100th anniversary, as well as CT lung cancer screening and the rise of enterprise imaging.
ACR asks CMS to revise CT lung cancer screening guidelines December 10, 2014 -- The American College of Radiology (ACR) is one of a group of organizations asking the U.S. Centers for Medicare and Medicaid Services (CMS) to revise its proposed guidelines for low-dose CT lung cancer screening to increase the number of individuals eligible for Medicare payment for the scans.
Coronary CTA plus stress MPI nails ischemia-causing lesions December 8, 2014 -- Combined dual-energy coronary CT angiography and CT myocardial perfusion imaging (CCTA-MPI) improves both the identification and discrimination of ischemia-causing coronary artery stenoses over CCTA alone, according to a Korean study presented at last week's RSNA meeting.
Radiation protection shielding drops dose for CT patients December 5, 2014 -- CHICAGO - Although cancers in the U.S. that may be attributable to radiation from CT are low -- estimates range from 1.5% to 2% -- patients still need to be shielded as much as possible, according to a presentation at the RSNA 2014 meeting. And with reusable, lead-free shields, it's not hard to do.
Fatty liver disease occurs with risky plaque December 4, 2014 -- CHICAGO - People with nonalcoholic fatty liver disease are very likely to harbor high-risk atherosclerotic plaque as well, creating a double health hit that may have a common origin, researchers from Boston reported at RSNA 2014.
Philips displays new spectral CT, MRI technology December 3, 2014 -- CHICAGO - Philips Healthcare is highlighting a number of new technologies in its booth at RSNA 2014, including spectral CT and a new 1.5-tesla MRI scanner, as well as advancements in ultrasound, molecular imaging, and interventional x-ray.
Trauma CT experts unveil fresh data on accident fatalities December 3, 2014 -- In all trauma cases, there is a higher incidence of upper cervical fractures compared with lower ones, and pedestrians involved in fatal accidents are far more likely than cyclists to suffer a cervical fracture, Swiss researchers reported at RSNA 2014.
Texture analysis sorts out indecipherable kidney lesions December 3, 2014 -- CHICAGO - Researchers from Johns Hopkins University have found a way to differentiate benign from malignant kidney lesions with great accuracy, solving a problem that has defied solutions since the advent of CT.
