This study was conducted to assess patterns and severity of COVID-19 pulmonary disease based on radiological imaging.\r\nMethods: A prospective observational study was conducted in a large tertiary care public sector teaching hospital of Karachi, Pakistan from June 2020 till August 2020. All confirmed and suspected COVID-19 patients referred for chest X-rays and computed tomography (CT) scans were evaluated along with RT-PCR results. Suspected patients were followed for RT-PCR. Radiological features and severity of imaging studies were determined.\r\nResults: Of 533 patients in whom X-rays were performed, majority had severe\/critical findings, i.e., 304 (57.03%). Of 97 patients in whom CT scan was performed, mild\/moderate findings were observed in 63 (64.94%) patients. Of 472 patients with abnormal X-rays, majority presented with alveolar pattern 459 (97.2%), bilateral lung involvement 453 (89.6%), and consolidation 356 (75.4%). Moreover, lobar predominance showed lower zone preponderance in 446 (94.5%) patients. Of 88 patients with abnormal CT findings, ground-glass opacity (GGO) 87 (98.9%) and crazy paving 69 (78.4%) were the most common findings. An insignificantly higher association of PCR positive cases was observed with severe\/critical X-rays (p-value 0.076) and CT scan findings (p-value 0.431).\r\nConclusion: Most common patterns on CT scans were GGO and crazy paving. While on chest radiographs, bilateral lung involvement with alveolar pattern and consolidation were most common findings. On X-rays, majority had severe\/critical whereas CT scan had mild\/moderate findings.\r\ndoi: https:\/\/doi.org\/10.12669\/pjms.37.5.4290\r\nHow to cite this:Khan SA, Manohar M, Khan M, Asad S, Adil SO.
