Chest CT finding and associated clinical factors of patients with COVID-19 pneumonia in Mahasarakham hospital

Abstract

Objective : To study chest computed tomography (CT) findings and associated clinical factors in patients with COVID-19 pneumonia in Mahasarakham hospital.

Methods : A retrospective study was conducted in patients with confirmed COVID-19 infection with pneumonia who underwent chest CT scan at Mahasarakham hospital from May 1, 2021 to December 31, 2021. Clinical information and laboratory finding including radiological reports, were retrospectively evaluated.

Results : Thirty patients with COVID-19 pneumonia and underwent chest CT were included (56.7% male and 43.3% female). The mean age of the patients was 60.6±10.7 yrs. The most common underlying disease in the study was diabetes (70.0%). Mixed ground-glass opacities with consolidation (46.7%) and pure ground-glass opacities (43.3%) were the most common main chest CT finding. CT abnormalities included bilateral lungs involvement (93.3%), lower zone predominance (56.7%) and peripheral distribution (86.7%). CT severity score was significantly correlated with CRP level and a CT score of ≥ 18 was associated with patient outcome.

Conclusion : Chest CT findings of confirmed COVID-19 pneumonia patient in this study were consistent with those of previous studies in other countries. In addition, CT severity score can aid in predicting COVID-19 disease outcome.
