BI-RADS breast density estimates as good as automated
February 16, 2017 -- Which is better when it comes to assessing breast tissue density -- man or machine? Turns out radiologists do just fine evaluating dense tissue using BI-RADS measures, compared with the performance of automated software, according to a new study published in the February edition of Radiology.
#MyRadGirlfriend No. 27: Good job on that case
February 16, 2017 -- Positive reinforcement can be an effective motivational tool in any workplace. The radiology reading room is no different, as Andy and Ruchi discover in the next installment of #MyRadGirlfriend.
Machine learning in radiology targets efficiency
February 16, 2017 -- While artificial intelligence is unlikely to replace radiologists any time soon, a new breed of software applications based on machine learning is poised to take on many of their tedious, repetitive, and time-consuming tasks -- improving productivity and freeing up more time.
MRI opens early window into autism
February 16, 2017 -- MRI scans in combination with a computer algorithm helped researchers predict which infants with older autistic siblings would exhibit autistic characteristics themselves by age 2, according to a study published online February 15 in Nature.
CMS: U.S. health spending to near 20% of GDP by 2025
February 15, 2017 -- The U.S. will see a modest increase in healthcare spending between 2016 and 2025, but that growth means the country will spend nearly 20% of its gross domestic product (GDP) on healthcare by 2025, according to a new analysis from the U.S. Centers for Medicare and Medicaid Services (CMS).
MRI start-up Alzeca takes aim at Alzheimer's disease
February 15, 2017 -- A new start-up company called Alzeca Biosciences is developing an MRI contrast agent that the company hopes will become an alternative to PET for early-stage diagnosis of Alzheimer's disease. The firm has hired imaging industry veteran Carlo Medici to leverage his experience in the contrast market.
DBT use inconsistent across the U.S.
February 15, 2017 -- Despite the demonstrated clinical benefits of digital breast tomosynthesis (DBT) for finding breast cancer, use of the technology for mammography is still inconsistent across the U.S., according to a study published online February 7 in Academic Radiology.
Do MRI scans cause genetic damage? Probably not
February 14, 2017 -- Should patients undergoing MRI scans be concerned about genetic damage? It's a relatively novel question, but one that's percolated to the surface in the past several years. Fortunately, a new literature review found little evidence to support the idea that MRI can cause genetic damage.
How should small papillary thyroid cancers be treated?
February 14, 2017 -- Patients with low-risk papillary thyroid cancer up to 1.5 cm in size can be safely managed by active surveillance, avoiding unnecessary surgery and any associated expense and potential complications, according to research published online in Thyroid.
CT better than echo for aortic annulus before TAVR
February 13, 2017 -- Aortic valve replacement may be more accurate when measurements are made with CT versus echocardiography, according to a January 24 paper in Academic Radiology. Coronary CT angiography measurements correlated well with 3D echocardiography results by most measures, making CT a suitable replacement for echo in planning transcatheter aortic valve replacement (TAVR) surgery.
