COVID-19 pandemic : CT chest in COVID-19 infection and prediction of patient’s ICU needs Osman, Ahmed M.; Abdrabou, Ahmed M.; Hashim, Reham M.; Khosa, Faisal; Yasin, Aya
Abstract
Background: With the tremendous rise in COVID-19 infection and the shortage of real-time reverse transcriptionpolymerase chain reaction (RT-PCR) testing, we aimed to assess the role of CT in the detection of COVID-19 infection and the correlation with the patients’ management. A retrospective study was conducted on 600 patients who presented with symptoms suspicious for COVID-19 infection between March and the end of June 2020. The current study followed the RSNA recommendations in CT reporting and correlated with the RT-PCR. CT was reviewed and the severity score was correlated with the patient’s management. Results: Four hundred sixty-six patients were included with a mean age of 46 + 14.8 years and 63.3 % were males. Three hundred forty patients were confirmed positive by RT-PCR. CT sensitivity was 92.6% while the RT-PCR was the reference. The CT specificity showed a gradual increase with the CT probability reaching 97.6% with high probability CT features. Ground-glass opacities (GGO) was the commonest findings 85.9% with a high incidence of bilateral, peripheral, and multilobar involvement (88%, 92.8%, and 92.8% respectively). Consolidation was found in 81.5% of the ICU patients and was the dominant feature in 66.7% of the ICU cases. CT severity score was significantly higher in ICU patients with a score of ≥ 14. Conclusions: COVID-19 infection showed typical CT features which can be used as a rapid and sensitive investigation. Two CT phenotypes identified with the predominant consolidation phenotype as well as severity score can be used to determine infection severity and ICU need.

Background: With the tremendous rise in COVID-19 infection and the shortage of real-time reverse transcriptionpolymerase chain reaction (RT-PCR) testing, we aimed to assess the role of CT in the detection of COVID-19
infection and the correlation with the patients’ management. A retrospective study was conducted on 600 patients
who presented with symptoms suspicious for COVID-19 infection between March and the end of June 2020. The
current study followed the RSNA recommendations in CT reporting and correlated with the RT-PCR. CT was
reviewed and the severity score was correlated with the patient’s management.
Results: Four hundred sixty-six patients were included with a mean age of 46 + 14.8 years and 63.3 % were males.
Three hundred forty patients were confirmed positive by RT-PCR. CT sensitivity was 92.6% while the RT-PCR was the
reference. The CT specificity showed a gradual increase with the CT probability reaching 97.6% with high
probability CT features. Ground-glass opacities (GGO) was the commonest findings 85.9% with a high incidence of
bilateral, peripheral, and multilobar involvement (88%, 92.8%, and 92.8% respectively). Consolidation was found in
81.5% of the ICU patients and was the dominant feature in 66.7% of the ICU cases. CT severity score was
significantly higher in ICU patients with a score of ≥ 14.
Conclusions: COVID-19 infection showed typical CT features which can be used as a rapid and sensitive
investigation. Two CT phenotypes identified with the predominant consolidation phenotype as well as severity
score can be used to determine infection severity and ICU need.
