The relationship between the severity of pulmonary involvement in the CT scan of patients with Covid-19 and the threshold cycle of SARS-CoV-2
INTRODUCTION: there is no clear relationship between the threshold cycle of COVID-19 and severity of pulmonary involvement in the CT scan of patients. Methods: 254 patients were included. The number of cycle of threshold virus, was extracted. The severity of pulmonary involvement was categorized bas...

| description | INTRODUCTION: there is no clear relationship between the threshold cycle of COVID-19 and severity of pulmonary involvement in the CT scan of patients. Methods: 254 patients were included. The number of cycle of threshold virus, was extracted. The severity of pulmonary involvement was categorized based on the percentage of involvement of each lobe Based on CT scan. The relationship between the CT number and the involvement in the CT scan, was measured.Results: 254 patients with COVID-19 such as 158 (62.2%) men and 96 (37.8%) women with a mean age and standard deviation of 17.785 ± 60.99 years. The average threshold cycle (CT Value) is 5.912 ± 19.38 and it’s minimum and maximum are 9 and 36. The percentage of right lung involvement was 29.7±46.7% and the percentage of left lung involvement was 29.8±47.8%. The number of people without conflict is 6 (2.4) %, with mild conflict 39 (15.4) %, moderate 65 (25.6%) and severe 144 (56.7%). The number of people without involvement of the right lobe is 11 (4.3%), score 1, 42 (16.5%), score 2, 75 (29.5%), score 3, 51 (20.1%), involvement Score 4, 75 (29.5%).The number of people without left lobe involvement is 12 (4.7%), score 1, 46 (18.1%), score 2, 71 (28%), score 3, 48 (18.9%), involvement Score 4, 77 (30.3%) .Conclusion: With the increase of lung involvement, the amount of threshold cycle has decreased, which can indicate the inverse relationship of threshold cycle with the severity of disease involvement. |
