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.
