Study of Ct Severity Index in Covid-19 Patients in Tertiary Care Hospital of Maharashtra

ABSTRACT

Background: Covid-19 is an infection that has widely and rapidly spread all over the world and become a pandemic with significantly impacts upon the socio-political milieu and health care system. CT scan has high sensitivity in patients infected by covid-19 when other test like nasal pharyngeal swabs may be insensitive hence CT severity index has potential impact on clinical decision making for covid-19. Material(s) and Method(s) 50 patients aged between 18 to 50 years admitted at covid-19 ward were studied with CT chest scan images 120kvp automatic tube current modulation (30-70 mAS) pitch 0.99 - 1.22 mm slice thickness 10 mm, FoV=350 mmx 350 mm. All images were reconstructed with a slice interval of 0.625 to 1.250 mm opacity, (GGO), consolidation GGO with consolidation, linear opacities, and crazy paving halo sign reverse halo sign. Result(s) CT chest findings had 4 (8%) has 1 lobe affected, 6 (12%) had 2 lobes affected, 5 (10%) had 3 lobes affected, 3 (6%) had 4 lobes affected, 1 (2%) had 5 lobes affected. 4 (8%) had GGO with consolidation, 14 (28%) had GGO, 1 (2%) had consolidation. Frequency of lobe, 6 (12%) had right middle lobe, 14 (28%0 had right lower lobe, 3 (6%) had left upper lobe, 4 (8%) left lingual lobe, 15 (30%) had left lower lobe. The distribution of opacification and pattern had rounded shape, 2 (4%0 had linear opacity, 4 (8%) crazy paving pattern, 1 (2%) reverse halo sign, 4 (8%) halo sign, 13 (26%) had peripheral distribution. CT severity score was 4 (8%) severe, 32 (64%) moderate, 14 (28%) mild. Conclusion(s) CT scan study has significant role in management of severity and possible outcome of covid-19. CT severity scores can be positively correlated with inflammatory laboratory markers. Copyright © 2022 Authors.
