Neuroimaging in the ED increased by 72% in recent years, with CTA a top contributor

Computed tomography and CTA for head and neck indications shot up by nearly 50% in patients 65 and older, according to patient-level claims data spanning 2007-2017.

Flexible X-ray detector made with lead-free materials performs well in early tests

Researchers think their work could play an important role in the future of imaging technology.

Disproportionate CT use for minor injuries is pushing emergency spine imaging utilization skyward

More than 800,000 of the 40 million annual ED visits in the U.S. now involve spine injuries, and imaging use for these traumas has tripled in some populations.

Doctors hope X-ray comparisons can boost COVID-19 vaccination rates

Can imaging results encourage more people to get vaccinated?

Society of Interventional Radiology issues guidance for minimally invasive lung cancer treatments
