Thorax CT protocol
CT imaging was performed in the supine position with raised arms, and at
the end of inspiration.Two radiologists experienced in the field of
thorax CT reviewed the thin-section and thick-section CT images
respectively and the decision was made. Radiologists have identified the
dominant appearances on CT images: ground glass density, crazy-paving
pattern, consolidation, and other findings.
All thorax CT images were classified as normal, non-COVID lung findings,
compatible with low probability COVID-19, intermediate probability
COVID-19, high probability-definite COVID-19 as previously defined
(13,21).
