Just how good is digital breast tomosynthesis, anyway?
May 16, 2022 -- It's been more than 10 years since the U.S. Food and Drug Administration cleared digital breast tomosynthesis (DBT) for marketing. But has DBT delivered on its much-anticipated promise? Experts weighed in on May 16 at the Society for Breast Imaging annual meeting. Read More
Potential for racial bias raises concerns for radiology AI
May 16, 2022 -- A preprint study that raised troublesome questions last year about potential bias in radiology artificial intelligence (AI) algorithms has now been formally published in the Lancet Digital Health with the same conclusions. Read More

Video from ISMRM 2022: Thoralf Niendorf on MRI field strength
May 16, 2022 -- Is the future all about low-field MRI, or will high-field scanners continue to have an important role to play in clinical imaging? For answers, we caught up with Prof. Thoralf Niendorf, PhD, at the International Society for Magnetic Resonance in Medicine (ISMRM). He remains an enthusiastic supporter of ultrahigh-field MRI.

How can radiology best cope with the contrast shortage?
May 13, 2022 -- How can radiology best cope with interruptions in the supply of iodinated contrast? Imaging facilities are scrambling to conserve contrast until supplies get back to normal, and a variety of sources are offering advice on how to conserve a material that up to now may have been taken for granted.

Can AI help target breast screening at high-risk women?
May 13, 2022 -- What's the most effective breast cancer screening strategy for women ages 40 to 49? Perhaps no screening at all for those deemed to be low risk by an artificial intelligence (AI) algorithm, according to research based on a simulation model published online May 6 in BMC Cancer.
