High-resolution computed tomography (HRCT) has emerged as a valuable tool in diagnosing and stratifying COVID-19 patients, especially where RT-PCR results are delayed. The modified CO-RADS classification system helps standardize reporting and assess the likelihood of COVID-19 infection based on imaging findings. Objective: To evaluate the spectrum of HRCT chest findings in confirmed COVID-19 patients using the modified CO-RADS classification and assess the association of radiological severity with clinical outcomes. Methods: This cross-sectional study included 110 COVID-19 patients categorized using the modified CO-RADS system. HRCT findings such as ground-glass opacities, consolidation, and crazy-paving were documented. Clinical variables including oxygen requirement, ICU admission, and hospital stay were compared across CO-RADS categories. Data were analyzed using SPSS version 26. Results: Most patients were categorized as CO-RADS 5 (42.7%) and CO-RADS 6 (21.8%). Ground-glass opacities (82.7%) and consolidation (61.8%) were the most common findings. Patients in CO-RADS 5–6 had significantly higher oxygen needs (69%), ICU admissions (19.7%), and hospital stays >7 days (52.1%). Logistic regression showed CO-RADS 5–6 (OR 6.8, p<0.001), age >50 years (OR 2.9, p=0.004), and comorbidities (OR 3.2, p=0.002) as strong predictors of severe disease. Conclusion: Modified CO-RADS classification effectively reflects both the radiological and clinical severity of COVID-19. Its integration into routine clinical workflow can improve early identification of high-risk patients and guide timely intervention.
