The 2019 novel coronavirus (SARS-CoV-2) caused a global pandemic, initially reported in Wuhan, China. It was named COVID-19 by the World Health Organization (WHO) in February 2020. Chest CT scans are crucial for early diagnosis and monitoring of COVID-19 pneumonia, as they show characteristic findings such as ground-glass opacity (GGO) and patchy consolidation, often involving the peripheral and lower lobes of the lungs. These findings help in assessing disease progression and guiding treatment. While RT-PCR is the gold standard for diagnosis, its limitations in early detection and availability have made chest CT an essential tool. The CT findings are non-specific but highly indicative of COVID-19, especially in patients with a history of exposure to Wuhan or close contact with infected individuals. Chest CT is also useful for tracking the disease's progression and monitoring treatment response. The typical CT features include multiple GGOs with consolidation, often distributed in the peripheral regions of the lungs. The number, extent, and density of GGOs on CT scans correlate with disease severity. CT is particularly effective in early detection and monitoring of the disease, playing a vital role in the control and management of the pandemic. The use of CT in clinical diagnosis was significant during the initial stages of the outbreak, especially in Wuhan, where it was used as a primary diagnostic criterion. The integration of CT findings with clinical and epidemiological data is essential for accurate diagnosis and effective public health response.The 2019 novel coronavirus (SARS-CoV-2) caused a global pandemic, initially reported in Wuhan, China.
