ARRS: Do NLST results translate to the real world?
May 4, 2017 -- NEW ORLEANS - When the National Lung Screening Trial (NLST) in 2011 reported a 20% lung cancer mortality reduction for high-risk smokers who were screened annually with low-dose CT, professional organizations lined up behind CT lung screening. But does the patient population studied in the NLST reflect the real world?
Contrast image processing boosts ultrasound performance
May 4, 2017 -- An image processing technique applied to contrast-enhanced ultrasound can deliver sharp, spatially compounded images without the need for additional transmit and receive cycles that can damage microbubble contrast, researchers have concluded.
