AI-based chatbot answers routine radiology questions
January 29, 2018 -- Interruptions are the bane of a radiologist's workday and can lead to interpretation errors. A chatbot based on artificial intelligence (AI) aims to reduce these disruptions while also providing information quickly to both clinicians and patients.  Discuss
AI's role in radiology evolving toward a promising future
January 25, 2018 -- Ask any radiologist about the role of artificial intelligence (AI) in medical imaging and the response will likely cover the gamut of clinical tasks. Should AI handle routine chores that take time but offer little reimbursement? Or should it provide detailed data to solve complex cases and confirm suspected conditions?  Discuss
Machine learning predicts working-memory performance
January 23, 2018 -- Can the combination of a machine-learning algorithm and diffusion MRI metrics of brain white-matter microstructure serve as a useful method for the early prediction of working-memory impairment? It appears possible, according to recent research from NYU Langone Medical Center in New York City.  Discuss
Artificial intelligence, brain MRI aid kids with hearing loss
January 15, 2018 -- U.S. and Chinese researchers have developed a machine-learning algorithm that analyzes MRI brain scans to predict how well deaf children may be able to develop language skills after receiving a cochlear implant, according to a study published online January 15 in the Proceedings of the National Academy of Sciences.  Discuss
Philips to move North American HQ to Cambridge
January 12, 2018 -- Philips plans to move the headquarters of its Philips North America business to a new site being developed in Cambridge, MA, from its current location 25 miles away in Andover, MA.  Discuss
Artificial intelligence guides lower PET tracer dose
January 11, 2018 -- In PET imaging, the amount of radiotracer dose correlates with the level of image quality. But what if artificial intelligence (AI) could enable PET to be performed using only 1% of current dose levels -- speeding exam times, decreasing radiation exposure, lowering costs, and alleviating shortages in radiotracers?  Discuss
CAD of chest tomosynthesis works best for new readers
December 26, 2017 -- Computer-aided detection (CAD) of digital chest tomosynthesis studies helped improve the diagnostic performance of inexperienced readers in a study by Japanese researchers published December 13 in Radiology. But CAD's effect was not statistically significant with physicians who had more experience.  Discuss
Quantitative analysis may help classify thyroid nodules
December 22, 2017 -- The echogenicity of solid thyroid nodules is often assessed qualitatively during evaluation on ultrasound. But this task can also be performed quantitatively, potentially offering a useful tool for determining malignancy risk, according to research presented at the RSNA 2017 meeting in Chicago.  Discuss
Deep learning analyzes PET for signs of dementia
December 22, 2017 -- A deep-learning algorithm that analyzed FDG-PET was able to differentiate between normal cognition and dementia. Such models could someday help radiologists diagnose Alzheimer's disease, especially if they don't see the condition often, according to a study presented at the RSNA 2017 meeting.  Discuss
AI can spot large pneumothoraces on chest x-ray
December 20, 2017 -- Artificial intelligence (AI) algorithms can automatically detect large pneumothoraces on chest x-ray exams -- potentially speeding up the detection and reporting of these critical findings, according to research presented at the RSNA 2017 meeting in Chicago.  Discuss
