Abstract
ABSTRACT
Background
Coronavirus disease (COVID-19) is the recent global health emergency making it
crucial for rapid diagnosis and intervention. Computed tomography (CT) is important
for screening, diagnosis and evaluating severity and disease progress.
Objective
To assess the CT changes in COVID patients and study its relationship with various
factors.
Method
A retrospective study was conducted at Norvic International hospital from August
2020 to November 2020 among RT-PCR positive symptomatic COVID cases who had
positive CT changes. CT imaging data were analyzed by radiology expertise. Statistical
analysis was carried out with the help of SPSS 16.
Result
Out of 120 patients, 75% were males and mean age was 54.70±15.56 years. The
mean CT severity score was 18.35±6.87. Pure ground glass opacities was seen in
74(61.7%), reticulations 89(74.2%) and crazy-paving pattern 28(23.3%). CT scans
with bilateral 118(98.3%) and peripheral involvement 109(90.8%) in all five lobes.
CT- severity score was positively correlated with oxygen and mechanical ventilation
requirement (P-value < 0.05 and 0.011 respectively).
Conclusion
CT findings including pure ground glass opacities, reticulations, bilateral and
peripheral involvement involving all five lobes were more frequent. Our data suggest
that CT-severity score significantly correlates with oxygen and mechanical ventilation
requirements.
