Imaging Informatics

 

Researchers from the Eindhoven University of Technology in the Netherlands recently presented in Nature Communications a newly developed spectrometer small enough to be inserted into a smartphone, according to an Eindhoven University of Technology release.  

As cyberattack become increasingly common incidents, healthcare professionals must push security to the forefront. In a presentation given at the annual meeting of the Radiological Society of North America (RSNA) in Chicago, Jim Whitfill, CMO of innovation Health Partners and President of Lumetis, described the current cybersecurity environment and detailed how professionals can take steps toward improving privacy.

Nicole Murphy, MS, a medical physicist at Northwestern Memorial Hospital in Chicago, and Christina Sammet, PhD, research assistant professor of Radiology at the Northwestern Feinberg School of Medicine and medical physicist at Ann and Robert H. Lurie Children's Hospital of Chicago, targeted three main objectives in relation to radiation dose management at RSNA 2017. 

Artificial intelligence (AI) is here to stay in radiology—and so are radiologists.

An analysis of nearly three million radiologic exams has confirmed prior research showing that physicians’ concentration tends to fall off toward the tail end of on-duty shifts. And yes, the diminishment in radiologists’ accuracy may be increased when they’re working especially long shifts and/or plowing through long worklists.

Columbia researchers map out calcium-moving proteins associated with cancer

A new study by researchers at Columbia University describes a newly understood way that calcium gets into the human body. The channel is directly related to the aggressiveness levels of certain types of cancer, so understanding the channel better could help physicians find new ways to understand or fight cancer.

 
Anti-CASPR2 antibodies found in different areas of the body in differently diagnosed patients

new study in the Journal of the American Medical Association Neurology set out to examine the implications of the presence of a certain type of antibody in some people’s cerebrospinal fluid.

 
Differences in brain activity could predict responses to stress

new study shows that the more a person’s brain can amplify neuroactivity during times of stress, the more resilient that person may be when trying to cope with trauma.

 
Patients using portals for imaging results are not interested in radiation risk

With patient-portal technology slowly but surely headed toward ubiquity—half of U.S. hospitals and 40 percent of physician practices now offer their patients such access—the time was right to ask what patients are doing, specifically with respect to radiology, on all those portals. 

Easy being green? Chlorophyll could be used in medical imaging

Photosynthesis isn’t just for plants anymore, researchers say. In a new study published in the journal Advanced Materialsdoctors argue that the green pigment in chlorophyll could help physicians peek inside human digestive tracts with certain kinds of imaging procedures.

 
Study: Aging memories not worse, just different

Aging and middle-age people’s forgetfulness might not mean their cognition is waning or even that their memories are slowing down or fading—just that they’re spending their cognitive energies elsewhere, in places that don’t happen to be “where did I leave the keys?” and “what’s that word again?”

 
Drinking more water could produce a satiated feeling in the brain

New research by the Society for the Study of Ingestive Behavior shows that people whose stomachs are more physically full feel more satiated during and after a meal.

 
Combining screening approaches could lead to earlier Alzheimer's detection

Using a combination of screening methods, it might be possible to diagnose Alzheimer’s disease earlier than ever before, according to a new study.

 
NIH’s Summers: Hype may be outpacing reality now, but AI really will improve patient care

In the July edition of the American Journal of Roentgenology, Ronald Summers, MD, PhD, senior investigator in the NIH Clinical Center’s laboratory for imaging biomarkers and computer-aided diagnosis, updated radiology watchers on the state of the art in fully automated abdominal CT interpretation. On July 7, he took questions on the material from HealthImaging.

Radiologists sharing more abdominal duties with computers

Notwithstanding the serious concerns raised by a recent fatal accident involving a Tesla car running on autopilot, self-driving cars are probably here to stay—but that doesn’t mean humans won’t still be driving. The same goes for fully automated abdominal CT image interpretation. It too is likely here to stay—but that doesn’t mean radiologists won’t still be reading.
