PET/CT of calcium forewarns of adverse cardiac event November 15, 2016 -- Patients with a normal stress test but evidence of calcium in coronary arteries on PET/CT scans are not immune from a serious adverse cardiac event within a year, according to a study presented on Monday at the American Heart Association annual meeting in New Orleans.
Can deep learning characterize breast tumors on SWE? November 15, 2016 -- Deep learning can accurately differentiate benign and malignant breast tumors on ultrasound shear-wave elastography (SWE) and outperform methods typically used in computer-aided diagnosis software, according to research published in the December issue of Ultrasonics.
4D CT of subtalar joint aids ankle instability assessment November 14, 2016 -- Dynamic quantitative CT with a 320-detector-row scanner of the subtalar joint offers detailed analysis of joint motion with a tiny radiation dose, revealing strong potential for the assessment of ankle instability, the authors of a new study conclude in the American Journal of Roentgenology.
PACS can shorten hospital stays, but challenges remain November 14, 2016 -- PACS not only improves efficiency and clinical decision-making but also shortens hospital stays, a study from Saudi Arabia has found. Major challenges to PACS usage remain, however, particularly the time taken to find images, recurrent system downtime, and insufficient training.
EQUIP: The FDA's new breast image quality program November 14, 2016 -- In its ongoing efforts to improve breast cancer detection rates, the U.S. Food and Drug Administration (FDA) has announced that it plans to use its Mammography Quality Standards Act inspection program to increase mammography image quality through a new venture it's calling Enhancing Quality Using the Inspection Program (EQUIP).
Math functions add color, detail to ultrasound images November 11, 2016 -- Can mathematical functions from 19th-century France help improve the quality of ultrasound images today? Researchers from the University of Rochester in Rochester, NY, say they can, serving as the basis for a method that uses color coding to reveal fine details that have previously been obscured.
MRI signals may show residual GBCA effects in the brain November 11, 2016 -- As researchers explore the potential long-term effects of gadolinium-based contrast agents (GBCAs), the direct measurement on MRI scans of T1 and T2 signal intensities in the brain may become a reliable method, according to a study published online October 31 in Radiology.
