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.

CT artifact-reduction software gets put through its paces

An independent review of four CT vendors’ metal artifact-reduction (MAR) solutions has shown that all four appreciably improve image quality. However, the reviewers noted additional artifacts and degradation of image quality, leading them to recommend carefully evaluating each software package’s algorithm case by case in clinical practice.

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.

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.
