Dense breast notification (DBN) laws that require recommending supplemental tests and cancer diagnosis after screening mammography boosted ultrasound use and cancer detection rates in a recent study of more than 1 million women across the U.S.

Interventional radiologists at UC-San Francisco have adopted the popular smart-speaker system Google Home (aka “Hey Google,” “OK Google”) for use in the surgical suite.

Using resting-state functional MRI (fMRI) to image the brains of human fetuses in utero, researchers have confirmed that functional connectivity differs between the sexes from very early on in neurodevelopment.

The Nashville region’s largest health-tech company, Change Healthcare, filed for a $100 million IPO March 15 in preparation for going public, according to the Nashville Business Journal.

Nearly half of CT scans ordered for patients presenting with dental infections are unnecessary, according to work published in the Journal of Oral and Maxillofacial Surgery, exposing patients to excess costs and physical risk where a more low-impact exam would have been sufficient.

It’s well established that widely used CPAP devices help give a good night’s rest to people with obstructive sleep apnea. Now an MRI-based study has shown the breathing assistance provided by continuous positive airway pressure also increases blood flow to, and blood volume in, the brain. 

A preliminary study published in Academic Radiology March 15 suggests dynamic contrast-enhanced MRI (DCE-MRI) can add value to the diagnosis of acute pancreatitis (AP) while subverting the use of perfusion CT, potentially paving the way for more irradiation-free analysis.

Compared to using standard or full-field digital mammography (FFDM), administering mammograms with digital breast tomosynthesis (DBT) reduces the risk of benign biopsies while maintaining a favorable cancer detection rate, according to research out of the U.K.

Google’s AI research group has shown that deep-learning algorithms can fine-tune ophthalmologists’ diagnosis of diabetic retinopathy on retinal fundus photographs, according to a study slated for publication in Ophthalmology. In the study, the physicians using the algorithm bested both AI alone and unassisted physicians on accuracy.

Researchers can more accurately and comprehensively study the brain with a novel concept known as diattenuation imaging (DI)—a neuroimaging method that allows scientists to measure the polarization-dependent attenuation of light throughout different parts of the brain—according to a study published in Scientific Reports.

When manually corrected by radiologists, an AI system for automatically detecting and segmenting colorectal metastases in the liver can improve interpretative efficiency, according to a study published online March 13 in Radiology: Artificial Intelligence.

A three-month joint investigation by Kaiser Health News and Fortune magazine has painted a disturbing picture of the state of electronic health records across the United States. The reporters spoke with more than 100 sources and found EHRs not only falling far short of their announced aims but also, in some cases, doing considerable harm.
