NEWS FROM RSNA 2018
Snoring Poses Greater Cardiac Risk to Women
Obstructive sleep apnea (OSA) and snoring may lead to earlier impairment of cardiac function in women than in men, according to a study presented at RSNA 2018. Moreover, the findings suggested that OSA may be vastly underdiagnosed among snorers. A common but dangerous sleep disorder, OSA causes an increased risk for left ventricular and, more rarely, right ventricular dysfunction in the heart.
OSA is the most common type of sleep apnea. It occurs when the throat muscles intermittently relax and block the airway while a person sleeps. While there are several symptoms of OSA—such as gasping for air during sleep, waking with a dry mouth, morning headache, and irritability—loud snoring is a common sign. Complications of OSA may include daytime fatigue and sleepiness, complications with medications and surgery, and cardiovascular problems.
Researchers investigated cardiac function in relation to diagnosed OSA and self-reported snoring from data available through UK Biobank. A national and international health resource, UK Biobank is open to researchers and follows the health and well-being of 500,000 volunteer participants. Its aim is to improve the prevention, diagnosis, and treatment of a wide range of serious and life-threatening illnesses.
For this study, data from 4,877 UK Biobank participants who had received a cardiac MRI were analyzed. The patients were allocated to three study groups: those with OSA (118 patients), those with self-reported snoring (1,886 patients), and those who are unaffected—without OSA or snoring (2,477 patients). There were 396 individuals who did not meet research criteria.

Miniaturized Pipe Organ Could Aid Medical Imaging
Researchers at the University of Strathclyde in Glasgow, Scotland, used high-resolution 3D printing to construct miniature pipe organs based on the musical instruments found in churches. The researchers say these small wonders may have applications for ultrasound imaging and offer the potential for higher-resolution scans.
Screen Time Study Shows Differences in Kids' Brains
An analysis from the National Institutes of Health of 4,500 9- and 10-year-olds found differences in brain structures between kids who spent seven or more hours a day on smartphones and mobile devices and kids who spent less time. Although the findings are notable, the researchers emphasize that it will take time to understand their significance.
Advanced Probes for High-Field MRI
A recent study from Michigan Technological University found that the continuity of magnetic fields in high-field MR imaging can be improved by changing the shape of the radio probes that are used. The technology was partially borrowed from one of the researchers’ work on cloaking devices.
CT Reconstruction Offers Clues to Ancient Human Anatomy
A team of researchers performed a 3D virtual reconstruction on the thorax of a Neandertal skeleton to learn more about how it moved and breathed. They used CT scans of the vertebrae, ribs, and pelvic bones of the 60,000-year-old specimen, the most complete Neandertal skeleton that has been found. The researchers say the scans reveal important features that shed light on how the evolutionary paths of Neandertals and Homo sapiens diverged. |

“Our study shows that diabetic patients are having changes within their deltoid muscles, demonstrated by a bright appearance on ultrasound, indicating that maybe earlier treatment is warranted. And patients who may be undiagnosed and missed, such as prediabetics or diabetics who haven’t been diagnosed yet, may be able to be diagnosed earlier.”
— Steven Soliman, DO, of Henry Ford Hospital in Detroit, on his organization’s research suggesting that an ultrasound of the deltoid muscle could serve as a predictor of type 2 diabetes |
