This review explores imaging's crucial role in acute COVID-19 assessment. HRCT (High Resolution Computer Tomography) is especially effective in detection of lung abnormalities. Chest radiography has limited utility in the initial stages of COVID-19 infection. Lung Ultrasound (LUS) has emerged as a valuable, radiation-free tool in critical care, and MRI shows promise as a CT alternative. Typical and atypical findings of COVID-19 by each of these modalities are discussed with emphasis on their prognostic value. Considerations for pediatric and immunocompromised cases are outlined. A comprehensive diagnostic approach is recommended, as radiological diagnosis remains challenging in the acute phase.

Keywords: COVID-19; chest radiography; high-resolution computed tomography (HRCT); lung ultrasound (LUS); magnetic resonance imaging (MRI).
