AI-based image reconstruction poses challenges
May 15, 2020 -- The use of deep learning to enhance image reconstruction has been considered to be a key application for artificial intelligence (AI) in radiology. A multinational team of researchers is warning, however, that the technology is prone to instability issues that could potentially even lead to a wrong diagnosis.  Discuss
Stroke scans drop by 40% during COVID-19 outbreak
May 8, 2020 -- The number of patients evaluated for stroke with imaging fell by 40% during the COVID-19 outbreak, according to a research letter published May 8 in the New England Journal of Medicine. The findings could be a sign that many stroke cases are not receiving appropriate medical care.  Discuss
