This project explains reverse transcription polymerase chain reaction tests (RT-PCR), how they are used to test patients for coronavirus disease (COVID-19), and how chest computed tomography (CT) imaging can assist in diagnosis. False negatives in RT-PCR testing, ground glass opacities (GGOs), pros and cons of using CT and RT-PCR tests together for diagnosis, and the use of artificial intelligence to diagnose COVID on a CT image are also discussed. COVID is a respiratory disease discovered in December of 2019 in Wuhan, China and has spread to the entire world. RT-PCR tests are the main form of diagnosis of COVID and chest CT imaging can show the damage the virus can cause to the lungs. Chest CT can show signs of COVID in the lungs in the case of a false-negative RT-PCR test, but COVID may also appear similar to other lung diseases on a chest CT. New artificial intelligence technology may have the ability to differentiate COVID from other lung diseases on a chest CT image, allowing for the possibility to rely on CT for COVID diagnosis.
