In response to the COVID-19 pandemic in Japan, the Japan Radiological Society made recommendations and issued early stage chest CT examinations guidelines to maintain an appropriate clinical practice. Surveillance on diagnostic imaging of viral pneumonia was conducted using computed tomography to detect the occurrence of COVID-19 pneumonia in Japan. The surveillance was proven to be essential, especially when the PCR testing system was inadequate in the early stages. In April of 2020, during the spread of COVID-19 infections in Japan, we collected chest CT images and created teaching data of COVID-19 pneumonia using the Japan Medical Image Database. Using the data, we then developed AI in diagnostic radiology in collaboration with the National Institute of Informatics.
