With the world experiencing another wave of the coronavirus pandemic that threatens to overwhelm hospitals and testing capacity, the ability to quickly diagnose COVID-19 based on alternative methodologies has become increasingly important. For patients with respiratory symptoms, review of CT scans emerged as a relatively reliable indicator of infection with SARS-CoV-2 from the first days of its emergence, but the need for more accurate readings remains.
An artificial intelligence-based system can accurately detect COVID-19 using thoracic CT scans in patients with respiratory symptoms, according to a preprint study published on arXiv.org. The system can also help monitor patients with the disease. Other teams have employed AI to speed diagnosis and develop clarity on the signature appearance of the disease in the lungs of symptomatic patients.
