Abstract
Computed tomography (CT) imaging and corticosteroid therapy have played pivotal roles in the diagnosis, monitoring, and management of COVID-19. This review provides evidence-based clinical perspectives on their applications, benefits, and limitations in patient care. CT imaging has proven invaluable in assessing disease severity, identifying pulmonary involvement, and guiding treatment decisions, particularly in moderate to severe cases. Characteristic radiological features such as ground-glass opacities and bilateral infiltrates serve as key diagnostic indicators, complementing RT-PCR testing. Concurrently, corticosteroid therapy, notably dexamethasone, has emerged as a cornerstone in managing severe COVID-19, mitigating hyperinflammatory responses and reducing mortality. However, inappropriate or prolonged steroid use has been linked to secondary infections, including mucormycosis, and delayed viral clearance. This review synthesizes current clinical evidence to highlight the need for judicious steroid administration, timing, and dosage guided by imaging findings and patient profiles. Integrating CT imaging with tailored corticosteroid therapy can optimize clinical outcomes, minimize complications, and improve overall patient management during and beyond the COVID-19 pandemic.
