Imaging

 

According to a new study published in Academic Radiology, in ultra-high-resolution computed tomography (U-HRCT) scans, a large matrix size maintains the spatial resolution and improves the image quality and assessment of lung diseases when compared to a 512-matrix size.  

Sitting for long periods of time may contribute to greater amounts of fat deposited around one's internal organs, according to a new study published in December issue of Obesity.  

The U.S. Food and Drug Administration (FDA) issued a new guidance on Jan. 9 warning that the lowest radiation dose possible should be used for pediatric patient X-ray exams. 

One unmistakable topic at RSNA 2017 was virtual and augmented reality—and how advancements will affect medicine. With numerous presentations and interactive booths at the annual conference in Chicago, the technologies are clearly growing in popularity in interventional radiology and health imaging. 

Researchers in China have discovered that depression and social anxiety cause noticeable structural abnormalities in the brain, according to a recent release from the Radiological Society of North America (RSNA).
