Deep-learning model detects cerebral microbleeds on MRI
May 28, 2019 -- A deep-learning algorithm can accurately detect cerebral microbleeds -- with few false-positive results -- by analyzing brain MR images, according to research published online May 20 in NeuroImage.  Discuss
AI can optimize risk stratification of thyroid nodules
May 24, 2019 -- An artificial intelligence (AI) algorithm improved the specificity of the American College of Radiology Thyroid Imaging Reporting and Data System, while also making the thyroid nodule risk-classification system easier for radiologists to use, according to research published online May 21 in Radiology.  Discuss
CAD software helps avoid contrast use in MS patients
May 23, 2019 -- Using computer-aided detection (CAD) software, 3D laboratory radiologic technologists can determine if patients with multiple sclerosis (MS) need a contrast agent for their brain MRI exam while they're still in the scanner, according to research posted online May 16 in the Journal of the American College of Radiology.  Discuss
Google AI accurately assesses CT lung screening scans
May 22, 2019 -- An artificial intelligence (AI) model developed by Google can assess cancer risk on CT lung cancer screening studies as well as, or even better than, experienced radiologists -- potentially enabling automated evaluation of these exams, according to research published online March 20 in Nature Medicine.  Discuss
