Abstract
The clinical status, i.e. oxygen need, of adult COVID-19 infection cases were linked with the 25 Point CT severity score in this investigation. An observational case control study after institutional research review board approval (NKPSIMS & RC and LMH / IEC-RADIOLOGYY/ 06/2020) including 123 case record of symptomatic cases presented to our hospital and who were RTPCR positive for COVID-19 infection, was collected for 3 months (August 2020 to Oct 2020). All patients underwent non-contrast HRCT scan on TOSHIBA Activion 16 slice CT (computed tomography). In our study, the mean age amongst the cases was ranging from 51-60 years [69.9% males, 30.1% females]. The oxygen requirements, as well as other variables such as age and sex, were found to be strongly correlated with CT severity score. CT severity score shows positive correlation with requirement of oxygen in cases with COVID-19.
