Initial CT Findings and CO-RADS Stage in COVID-19

Comparison of Initial CT Findings and CO-RADS Stage in COVID-19 Patients With PCR, Inflammation and Coagulation Parameters in Diagnostic and Prognostic Perspectives

This study aims to determine whether patients with different real-time reverse transcriptase-polymerase chain reaction (PCR), chest computed tomography (CT) and laboratory findings have different clinical outcomes.

This study aims to determine the rates of PCR positivity and CT findings in hospitalized patients with a diagnosis of COVID-19, to determine whether there is a difference in mortality and need for ICU between patients grouped according to the PCR positivity and presence of CT findings, and to evaluate the effect of the CO-RADS stage on these outcomes. Moreover, it is to compare the effects of inflammation and coagulation markers and CO-RADS stage on the severity of the disease

Inclusion Criteria:

Exclusion Criteria:

• Patients with negative SARS-CoV-2 PCR test, pneumonia on CT but not given Covid-19 treatment by not considering Covid-19 by their doctor will not be included.
