Background: Reverse transcription polymerase chain reaction (RT-PCR) is the standard gold for COVID-19 detection; however, results often require 5-6 h, whereas CT examination results can be obtained much faster. Chest computed tomography (CT) has a potential role in diagnosing, detecting complications, and prognostication of COVID-19. Objectives: The aim of the study was to evaluate the effectiveness of CT as a diagnostic method for detection of COVID-19 in asymptomatic patients and to compare the diagnostic validity of CT with RT-PCR test. Materials and Methods: This retrospective and observational study analyzed patients without respiratory symptoms who underwent computed chest tomography as hospitalization protocol from April 2021 to June 2021. A total of 399 CT scans were performed. Results: Considering the typical findings by tomography, there is a poor concordance between the two diagnostic methods. There was no relationship between the negative findings and the negative CT scans, even in the negative findings. Conclusion: We do not recommend performing tomography together with RT-PCR as a detection method in asymptomatic patients since no concordance was observed between the tests. We recommend only detecting COVID-19 in asymptomatic patients using the PCR test.
