Imaging Informatics

 

Free-text radiology reports can be automatically classified by convolutional neural networks (CNNs) powered by deep-learning algorithms with accuracy that’s equal to or better than that achieved by traditional—and more labor-intensive—natural language processing (NLP) methods.

Researchers in the radiology department at the University of California, San Francisco (UCSF)—led by of Sabrina Ronen, PhD, director of the Brain Research Interest Group (RIG) and professor in the department of radiology and biomedical imaging at UCSF—are in the process of developing new, non-invasive imaging biomarker indicators to address multiple types of cancer, according to a recent UCSF press release

Many radiologists use Twitter and LinkedIn for staying up on matters related to their work. A study published online Nov. 12 in the Journal of the American College of Radiology shows they’d do well to tap, for the same purposes, the social-media platform that’s commonly thought of as a purely personal online space.

A group of German researchers has developed a nuclear medicine test that can detect infections in kidney transplant tissue, according to a study published in Journal of Nuclear Medicine

Members of the online radiology community, take note: Personally tweeting links to articles posted ahead of print in online medical journals doesn’t increase overall pageviews of these articles. It just increases the number of people who find their way to any given “article in press” via Twitter.

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.

IR team uses active dosimetry to reduce workers’ radiation exposure

Interventional radiology (IR) staffers at 189-bed Lawrence General Hospital in Massachusetts have shown that a commercially available real-time dosimetry system works well in reducing occupational radiation exposures.

First fruits arrive from the HIMSS-SIIM enterprise-imaging workgroup

If enterprise imaging refers to visual clinical data acquired in nearly every corner of a healthcare institution’s realm—meaning not only radiology and cardiology but also pathology, ophthalmology, dermatology and maternal-fetal medicine, just to name a few—then enterprise-imaging governance refers to the people charged with putting all that data together to render it useful for clinical, financial and administrative end users. 

Enterprise innovations at SIIM 2016

Change is in the air, can you feel it? Of course you can! You work in healthcare, change is what you do.

Working together across the enterprise

Communication technology has long been credited with making the world “smaller.” But even today, some of the challenges with working across a healthcare enterprise seem quite large.

MR goes beyond imaging concussion to fleshing out its features, case by case

When it comes to imaging the brains of concussed patients, CT is the workhorse plowing the field and MRI the thoroughbred mastering the equine obstacle course.
