AI uses features outside nodules to predict malignancy
December 19, 2018 -- An artificial intelligence (AI) algorithm was able to distinguish benign from malignant nodules in cases of suspected non-small cell lung cancer on CT scans by analyzing the area immediately outside of the nodule, according to a December 18 paper in Radiology by researchers from Case Western Reserve University.  Discuss
AI could bring ultralow-dose imaging to amyloid PET
December 18, 2018 -- With the help of artificial intelligence (AI), researchers have developed a way to generate diagnostic-quality images from PET/MR scans to detect amyloid deposits with considerably less radiotracer dose. Their findings were published online December 11 in Radiology.  Discuss
New algorithm overcomes imaging AI challenges
December 17, 2018 -- Researchers have developed a new artificial intelligence (AI) algorithm designed to address two of the biggest challenges in imaging AI: its "black box" nature and the need for large amounts of image data to train the models, according to a study published online December 17 in Nature Biomedical Engineering.  Discuss

December 12, 2018 -- A new mammography technique that uses an artificial intelligence (AI) algorithm to map the biological tissue composition of tumors on dual-energy mammography images could help reduce unnecessary biopsies, according to a study published online December 11 in Radiology.  Discuss
AI algorithm detects all intracranial hemorrhage types
December 6, 2018 -- An artificial intelligence (AI) algorithm can detect all types of intracranial hemorrhage on noncontrast head CT studies, showing potential for use in all clinical scenarios that involve detecting and tracking this critical condition, according to research presented at the recent RSNA 2018 meeting in Chicago.  Discuss
Beyond the black box? AI algorithm explains decisions
December 5, 2018 -- Yale University researchers have developed an artificial intelligence (AI) algorithm for classifying liver lesions on MRI scans that explains the reason for its decisions. The algorithm could address concerns about the "black box" nature of AI, according to research presented at last week's RSNA 2018 meeting.  Discuss
Survey finds German medical students don't fear AI
November 29, 2018 -- CHICAGO - While the majority of medical students in Germany are aware of the discussion of artificial intelligence (AI) in radiology, most are unafraid of being replaced by AI and are optimistic that it will improve radiology as well as medicine in general, according to research presented on Thursday at the RSNA 2018 meeting.  Discuss
