Patient Selection
Chest Computed Tomography of patients who admitted to our hospital’s emergency department with suspicion of COVID-19 between March and June 2020 were enrolled. Among these, patients who have RT-PCR tests performed via nasopharyngeal and oropharyngeal swap specimens were selected. PCR tests had been finalized within 24 to 96 hours at the first days of the epidemic in our country. Patients whose CT scans performed with a time gap longer than 48 hours with PCR testing were excluded from the study.
Ethics committee approval was received for this study both from the institutional Ethical Committee and The Ministry of Health.
