Chest CT detects minor lung lesions in patients at an early stage of disease, demonstrating its utility in guiding the diagnosis. In a patient with a history of close contact with a SARS-CoV-2-infected patient, early manifestation of bilateral, multifocal, and peripheral ground glass opacities on a chest CT scan might be a sign of a 2019 novel coronavirus infection. Thus, chest CT is suggested as an important tool for SARS-CoV-2 infection diagnosis.
