A study conducted at the Shanghai Public Health Clinical Center evaluated 51 patients with laboratory-confirmed 2019-nCoV infection using chest CT scans. The study aimed to characterize the clinical, laboratory, and imaging features of 2019-nCoV pneumonia. Most patients (98%) had a history of contact with individuals from Wuhan, China. Common symptoms included fever (96%) and cough (47%). Laboratory findings showed normal or reduced white blood cell and lymphocyte counts in most patients. Chest CT findings revealed that 77% of patients had pure ground-glass opacity (GGO), 75% had GGO with reticular and/or interlobular septal thickening, and 59% had GGO with consolidation. Pure consolidation was present in 55% of patients. Bilateral lung involvement was common, with lesions predominantly in the posterior and peripheral parts of the lungs. Lesions increased in size and density over time, with more consolidation observed in patients with a longer interval between disease onset and CT scan. Older patients had more consolidated lesions than younger patients. Follow-up CT scans showed improvement in 54% of patients and progression in 31%. The study concluded that patients with fever and/or cough, GGO lesions in the peripheral and posterior lungs on CT, and a history of exposure to Wuhan are highly suspected of having 2019-nCoV pneumonia. The study highlights the importance of CT in diagnosing 2019-nCoV pneumonia and the need for further research to understand the disease's progression and treatment.A study conducted at the Shanghai Public Health Clinical Center evaluated 51 patients with laboratory-confirmed 2019-nCoV infection using chest CT scans.
