Research presented at this year’s Society of Interventional Radiology conference in Austin, Texas, suggests virtual reality (VR) could be useful to interventional radiologists, improving treatments using real-time 3D images from inside a patient’s vessels.

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. 

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.

On scans from several different MRI techniques, regular alcohol consumption correlates with regional changes in the brain as well as with various cognitive abilities. And those most sensitive to alcohol’s viewable and observable effects are men and individuals whose faces blush upon intake.

Family physicians as well as medical students appreciate the opportunity to bone up on radiology via online classrooms using the popular Second Life platform. And while doctors tend to immerse themselves in the process with somewhat lower intensity, all seem to readily take to radiology training with avatars and other features of the virtual world. 

Whole-body PET/CT with the standard radiotracer 18F-FDG is a dependable screening tool for catching many metastases, distant as well as regional lymphatic, according to researchers at the University of Minnesota.

Kinematic quantitative 4D CT can help differentiate patients with subtalar joint stiffness and chronic ankle instability, reported authors of a March 5 study published in the European Journal of Radiology. The technique may better personalize care for patients with ankle joint pain.

The research team also found combining 4D CT and technetium-99m sestamibi SPECT/CT did not improve diagnostic performance compared to 4D CT alone.

Individual language is significantly impacted by what we hear, and a team of researchers from New York University used various imaging methods to determine that our brain’s pathways play a central role in speech development.

The technique, which combines MRI with a manganese-based contrast agent, could help researchers better understand how neurons communicate in the brain, according to the study published online Feb. 22 in Nature Communications. 

Royal Philips and Microsoft recently unveiled their latest technological collaboration for the "operating room of the future," which combines Philips’ Azurion image-guided therapy platform and Microsoft’s newly released HoloLens 2 holographic augmented reality (AR) headset to help create novel AR applications for image-guided minimally invasive therapy. 

The new platform, affectionately called ‘Herman,' analyzes complex patterns in images of pathogen and human cell interactions, and can do so in a fraction of the time normally required.
