Neural networks read mammograms as well as radiologists
March 3, 2017 -- VIENNA - Deep artificial neural networks can read mammograms as well as radiologists, according to research from Switzerland presented at ECR 2017 on Thursday. Neural networks can also be trained with a relatively small amount of data, the group found.
CAD beats readers for subsolid lung nodules
March 3, 2017 -- VIENNA - A computer-aided detection (CAD) scheme outperformed experienced human readers in detecting subsolid nodules as well as cancers in data from more than 2,000 lung cancer screening subjects, researchers reported on Thursday at ECR 2017.
Software quantifies emphysema on MDCT images
March 2, 2017 -- VIENNA - An automated software algorithm can be used to quantify emphysema on MDCT studies, offering radiologists a useful tool for diagnosis and follow-up of chronic obstructive pulmonary disease, according to research presented on Thursday at ECR 2017.
Artifact reduction algorithm boosts utility of 4D CT
February 27, 2017 -- Four-dimensional CT images can improve radiation therapy planning in the upper thorax and abdomen, but motion artifacts often make the images nondiagnostic. New algorithms that provide deformable registration and respiratory motion simulation clear up the picture.
Machine-learning analysis of heart motion predicts survival
February 9, 2017 -- A machine-learning survival model based on 3D cardiac motion predicts outcomes beyond conventional risk factors in patients with pulmonary hypertension, according to a new study from the U.K. and Singapore. Semiautomated analysis of the cine MR images could potentially be used to guide patient management.
Virtual coaching takes on x-ray training
February 3, 2017 -- A New Zealand start-up called Virtual Medical Coaching aims to reinvent radiographer and radiologic technologist training by making it more virtual, more personalized, more flexible, and above all more relevant for students.
CAD finds vertebral lung cancer metastases
January 27, 2017 -- Readers using an original computer-aided detection (CAD) algorithm that subtracts thoracic 3D CT images from follow-up images found more vertebral metastases than readers working unaided, according to a study in PLOS One.
PET/CT CAD finds common spinal metastases
January 23, 2017 -- A new multipurpose computer-aided detection (CAD) algorithm was able to detect and characterize different kinds of spinal metastases in PET/CT images automatically and accurately, say researchers from two U.S. institutions. The fully automated system could help doctors diagnose and manage patients with the most common musculoskeletal metastases.
Top 10 healthcare 3D printing events of 2016
January 18, 2017 -- 2016 was an exciting year for 3D printing in healthcare. Big investments, mergers and acquisitions, and strategic partnerships from front-runners of the industry seem to mark the beginning of an exciting new era. Neuroradiologist Dr. Jenny Chen of 3DHeals lists the 10 events she thinks were most important in 2016.
3D-printed kidneys change preop surgical planning
January 16, 2017 -- Even experienced nephrologists can improve their preoperative planning when 3D-printed kidneys are available, according to the results of a new study in Abdominal Radiology. 3D models can shift some surgeries to less-invasive options after the translucent printed models are used for planning.

3DHeals conference explores 3D printing and more

3D printing is revolutionizing medicine -- and radiology with it. But what's the best way to learn about this emerging discipline? The 3DHeals International Conference, being held in San Francisco on April 20, will explore 3D printing in healthcare with an eye on virtual reality, augmented reality, and artificial intelligence.
