Is visual or automated analysis best to assess Alzheimer's?
February 10, 2016 -- Should visual or automated analysis be used with PET imaging to predict a person's progression from mild cognitive impairment to dementia due to Alzheimer's, based on a two-year follow-up evaluation? It could depend on the radiotracer involved.
Cardiac perfusion PET/MRI may be more accurate than SPECT
January 25, 2016 -- Perfusion imaging with PET/MRI could offer a "comprehensive myocardial ischemic evaluation" with shorter scan times than SPECT and a lower radiation dose for patients, according to a pilot study from Washington University and Barnes-Jewish Hospital in St. Louis.
Study finds U.S. nuclear cardiology doses are too high
January 5, 2016 -- Radiation doses for myocardial perfusion imaging exams in the U.S. are significantly higher than those in the rest of the world. Few U.S. sites adhere to best practices for dose reduction, and the U.S. fee-for-service model also contributes to the disparity, according to articles published online December 28 in JAMA Internal Medicine.
Weight-based protocols reduce PET/CT radiation dose
December 28, 2015 -- Patient-specific, weight-based imaging protocols for FDG-PET/CT can significantly reduce CT radiation dose without compromising diagnostic image quality, according to a study from American University of Beirut in Lebanon.
MBI: The unsung hero of dense breast imaging?
December 18, 2015 -- Is molecular breast imaging (MBI) the unsung hero for women with dense breast tissue? Researchers from the Mayo Clinic in Rochester, MN, believe it might be due to its ability to image tumor function. They presented their work with the modality at RSNA 2015.
PET/MRI shows value for cardiac sarcoidosis
December 14, 2015 -- Simultaneous cardiac PET/MRI is better than PET/CT for detecting cardiac sarcoidosis, offering diagnostic image quality and less radiation dose, according to a study presented at RSNA 2015.
Imaging for coronary artery disease on the decline
December 2, 2015 -- CHICAGO - The utilization rates of noninvasive imaging in patients with suspected coronary artery disease show a precipitous decline, with coronary CT angiography greatly underused, according to a study presented on Wednesday at RSNA 2015.
App-based US, spectral CT pace Philips RSNA launches
December 2, 2015 -- CHICAGO - New technologies being highlighted by Philips Healthcare at RSNA 2015 include its novel Lumify app-based ultrasound model, as well as a CT scanner designed to make spectral scanning more routine.
Big-data cloud launch spearheads GE RSNA news
December 2, 2015 -- CHICAGO - The launch of a new service for analyzing healthcare data in the cloud is spearheading the product introductions by GE Healthcare at this week's RSNA 2015 meeting. Other introductions include new ultrasound and CT systems.
Siemens RSNA launches range from x-ray to PET/CT
December 1, 2015 -- CHICAGO - At this week's RSNA 2015 meeting, Siemens Healthcare is unveiling a range of new imaging technologies, from a robotic x-ray room to a new entry-level PET/CT scanner. The firm is also talking up a regulatory clearance for CT lung cancer screening that it received just before the show opened.
