Dr Chandrakant Manmath Shetty | Dr Mahima Rishabh Kapoor
Abstract: Background: A wide variety of computed tomography (CT) findings in COVID-19 have been reported in different studies, and the CT findings differ according to the stage of the disease and disease severity and associated co-morbidities. The study aimed to determine the role of HRCT chest in the evaluation of COVID 19 patients. Methods: This is a retrospective study done at K. J. Somaiya Medical College & Hospital, Sion, Mumbai. The Present Study was on 160 hospitalized patients who underwent HRCT CHEST with symptoms of COVID 19. Results: Most of the patients in the fifth and sixth decade of age group with a mean age of 58.36?15.36 years. There was a male preponderance (68.13% male and 31.88% female). Out of 160 patients, 145 patients (90.6%) were symptomatic, while 15 patients (9.4%) were asymptomatic. 53.8% of patients had some or the other underlying comorbid disease in the sample population. HRCT chest of the study population showed the variety of opacity characteristics. Out of 160 patients, 61 (38.13) patients had pure Ground glass opacities (GGO) while another 82 (51.25) patients had both mixed GGO. In early phase of the CT scan, 66.67% patients had GGO while in the intermediate phase high percentage of (56.1%) of the patients had mixed GGO & consolidation. The lobe involvement was measured using the Ct severity scoring system. In this study majority (59.38%) of the patients had a CT severity score between 1-7 indicating mild disease, 35.63% patients had CT score 8-15 indicating moderate disease while only 5.00% had CT severity score 16-20 indicating severe disease. Conclusion: HRCT chest in COVID-19 patients had significant diagnostic and prognostic importance as positive CT findings more prominent in symptomatic patients and comorbid patients. CT imaging was found to be useful in predicting a patient?s clinical recovery or disease progression.
