MRI detects cause of vision problems in astronauts
May 5, 2017 -- MRI scans of astronauts who spent time at the International Space Station confirm that increased orbital and ventricular cerebrospinal fluids cause vision problems that worsen with extended time in space and linger after the travelers have returned to Earth.
Diagnostic reference levels reduce CT doses
May 5, 2017 -- Establishing diagnostic reference levels (DRLs) for radiation dose is a powerful tool for reducing radiation exposure in CT, according to a study by Canadian researchers published in the May issue of the American Journal of Roentgenology.
Study: Reject pelvic x-rays if axial rotation exceeds 10┬░
May 5, 2017 -- Researchers from Lebanon have found they can estimate the pelvic axial rotation of children and adults during x-ray acquisition, and any x-rays in which the axial rotation exceeds 10° should be discarded.
U.S. House passes bill to repeal and replace ACA
May 4, 2017 -- The U.S. House of Representatives today narrowly passed a bill to repeal and replace the Patient Protection and Affordable Care Act (ACA). The bill gives states more control over the essential health services they cover, but it also raises the specter of large-scale disruption in insurance coverage, particularly for individuals with pre-existing conditions.
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.
