Unsupervised AI yields automated COVID-19 survival predictions
August 5, 2021 -- An "unsupervised" artificial intelligence (AI) model -- that is, one trained without image annotations -- can yield accurate predictions of a COVID-19 patient's survival based on their chest CT exams, according to research published online in Medical Image Analysis. Read More
LVO stroke patients benefit from going directly to angiography suite
August 2, 2021 -- Patients with suspected large vessel occlusion (LVO) stroke can have better long-term outcomes if they are transferred directly to the angiography suite for diagnosis upon admission, according to research published online August 2 in JAMA Neurology. Read More
