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.

Imaging library launched for traumatic brain injury

The American College of Radiology is working with the nonprofit research organization Cohen Veterans Bioscience to create a reference library for neuroradiologists, neurologists, emergency docs and all others diagnosing, treating or researching mild traumatic brain injury (TBI). 

New pediatric heart MR faster, more adaptable to remote care

A newly proposed technique for contrast-enhanced 3D MR angiography is not substantially better on image quality than standard sequential 2D for planning the care of children with congenital heart disease. However, the 3D approach allows faster and offline planning, thereby reducing scan times significantly.

Rounding radiology residents improve patient care, referrer communication—and their specialty’s status

Members of a large academic radiology department have shown the value that resident-driven imaging rounds can add to patient care in a multidisciplinary care-delivery model. In the process, they’ve demonstrated a way the specialty can spotlight its contributions in the era of bundled payments and outcomes-oriented incentives. 

Cancer guidelines after active treatment have low specificity, consistency

In a retrospective cross-sectional analysis, a group of researchers examined the specificity and consistency of recommendations for cancer surveillance after effective treatment across guidelines.

Q&A: Southers sheds light on brain imaging being used to combat mental health stigma

A recent study using MRI found that ADHD is a disorder of the brain. Barry Southers, MRI program director at University of Cincinnati Advanced Medical Imaging Technology (AMIT) Program, spoke with Health Imaging about how brain imaging can fight the stigma associated with mental health.

Mayo Clinic: What's the role of tumor sequencing in women with breast cancer?

In a new study published in the Journal of the National Cancer Institute, researchers from Mayo Clinic reported results of a prospective tumor sequencing study in women receiving chemotherapy prior to breast surgery.

Deep learning expected to expand exponentially in radiology

The worldwide market for radiology-specific deep learning will soar from around $40 million next year to some $300 million by 2021, largely on the wings of increasing demand for imaging combined with radiologist shortages like the one Scotland is facing.

Exercising can help 'attenuate age-related neurodegeneration'

Assistant professor of psychiatry at Boston University School of Medicine, Scott Hayes, PhD, and his research team, were prompted to do research on cardiac fitness and brain health in older adults after serveral animal studies that showed physical activity positively impacting memory performance and brain regions critical for memory. 

UCLA neuros: Let imaging be the birthing, raising ground for cerebrovascular health

The HHS department, collaborating with various private-sector partners, launched the Million Hearts initiative to fight heart attacks and strokes back in 2011. The Precision Medicine Initiative and BRAIN Initiative followed, both with stroke as a key target. Well and good, but the concerted stroke-busting efforts to date have mostly stressed genomics, novel biomarkers and innovative data. Where’s the imaging? 

Hospital staff prepares for potential failure of electronic imaging services

Imagine the electronic management system for imaging services fail, leaving radiologists with delayed bookings and examinations of images. Would a hospital's administration, medical staff and/or patients be ready for something like this?
