How Artificial Intelligence is Helping Brazil Doctors Fight Deadly Covid-19

News 18  

Under-testing remains a huge problem in the sprawling South American country, but AI is helping fill the gap, thanks to a system called RadVid-19 developed using algorithms from German company Siemens and Chinese firm Huawei. "The software identifies those areas and estimates the probability of a case of COVID-19," says Marcio Sawamura, deputy head of the radiology center at the University of Sao Paulo Clinical Hospital. But it can help doctors decide what treatment to pursue during the sometimes long wait for lab results to come back, in a country where no large-scale testing campaign has been launched and President Jair Bolsonaro faces criticism for downplaying the pandemic. - Creativity in crisis - "Since Brazil is testing less than it should, CT scans and X-rays end up being used as diagnostic tools," says Arthur Lobo, a radiologist in the northern city of Belem.
