Abstract:

Objective: To analyze the chest x ray findings in Covid-19 patients, presented at Nalanda Medical College and Hospital (NMCH), Patna, based on chest x-ray classification of British Society of Thoracic Imaging (BSTI)Methods: In this observational study, 87 Reverse Transcriptase-Polymerase Chain Reaction (RT-PCR) COVID-19 positive patients above 14 years of age screened at NMCH, Patna from 15th July 2020 to 30th September 2020 were included. CXR findings were classified according to BSTI classification and documented in frequencies and percentages. Results: Out of total 87 number of patients, 7 patients (8.04%) had normal chest x rays, 15(7.24%) patients had classic bilateral, peripheral and basal consolidation/Ground glass opacity (GGO), 55 (63.21%) patients had indeterminate group i.e those that did not fit in classic or non - Covid-19 or had poor quality film,10(11.49%) patients had non - Covid-19 chest x rays.Conclusion: In this study, Covid-19 chest x rays generally presented as a spectrum of pure ground glass opacity, mixed GGO to consolidation in bilateral peripheral middle and lower lung zones. BSTI chest x rays reporting classification of covid-19 is valid in our patients with addition of middle zonal involvement in classical covid-19 criteria as opposed to just lower zone involvement.
