The Protecting Access to Medicare Act (PAMA) mandating the use of a clinical decision support (CDS) system when ordering advanced imaging tests could affect up to six million emergency department visits annually, according to estimates published in a Jan. 29 Radiology study. The law is set to go into effect in January 2020.

Researchers from Stanford University in California have published a large, public dataset containing more than 224,000 chest x-rays from more than 65,000 patients to train AI algorithms. The team also announced a competition inviting developers to submit their chest x-ray interpretation models to detect pathologies more accurately than certified radiologists. 

Using fMRI, a team of researchers discovered combat veterans with severe post-traumatic stress disorder (PTSD) demonstrate distinct patterns in how their brain and body respond to learning danger and safety. The study may help explain why some experience more severe symptoms than others.

In 2018, the FDA approved a total of 106 new medical devices including medical imaging technologies—surpassing their record in 2017 of 99 novel device approvals, according to a recent statement from FDA Commissioner Scott Gottlieb, MD, and Jeff Shuren, MD, director of the Center for Devices and Radiological Health.

Researchers at Northwestern University in Evanston, Illinois have developed a noninvasive, three-dimensional (3D) imaging tool able to capture blood flow and oxygenation within the capillaries of a human, according to research published in the journal Light: Science & Applications. The technique could help detect conditions from headaches to cardiovascular disease, sooner.

A radiologist who runs a private practice in Florida was arrested in Auburn, Massachusetts, Sunday for illegal possession of a handgun and for allegedly offering to pay for sex, according to a report by the Boston Globe.

In an effort to destigmatize mental illness and help patients find better treatments, researchers from Virginia Tech’s Fralin Biomedical Research Institute in Roanoke, Virginia trained a machine learning algorithm with brain fMRI scans to diagnosis mental disorders more accurately than standard methods, according to a recent report by The Verge.

Jeffrey S. Klein, MD, will be stepping down as editor of the Radiological Society of North America (RSNA)’s journal RadioGraphics. In the wake of the announcement, the journal is now looking for a new editor.

A pair of specialists recently took on the topic of the word "cancer" in a Jan. 23 viewpoint published in The BMJ, arguing that changing the terminology could ease patient anxiety or create more fear.

New research involving breast cancer patients in the U.S. Military Health System found that black women wait longer to undergo breast cancer surgery after being diagnosed with the disease than white women, according to a study published Jan. 23 in JAMA Surgery.  

A team of national researchers has identified a set of multiparametric MRI-based guidelines and clinical features which can help clinicians easier determine a patient’s risk that their prostate cancer will spread, according to a Jan. 22 study published in Radiology.

“Students rely on us to understand how radiology is incorporating new technology and what the future of the field will look like for them, but many of us are ill prepared to teach the younger generation about this, mostly because we ourselves are not sure,” Allison Grayev, MD, wrote in an editorial published in Academic Radiology.
