Abstract
During the COVID-19 pandemic, diagnostic imaging and pharmacological interventions have played vital roles in disease management. However, the misuse of computed tomography (CT) scans and corticosteroids has raised concerns regarding patient safety, radiation exposure, and secondary infections. This review consolidates evidence from international and Indian sources (WHO, ICMR, AIIMS, 2020–2024) to evaluate the clinical rationale, risks, and best practices in the use of CT scans and steroid therapy for COVID-19. Findings indicate that while CT imaging supports disease severity assessment and complication monitoring, its routine use in mild cases is unjustified. Similarly, corticosteroids such as dexamethasone significantly reduce mortality in severe cases but are harmful when administered prematurely or at high doses. Proper adherence to evidence-based guidelines is essential to balance diagnostic efficacy and treatment safety.
