Early diagnosis of coronavirus disease of 2019 (COVID-19) can help restrict the disease by allowing infection control measures to be implemented quickly, limiting the disease's spread. Although nasopharyngeal swab nucleic acid testing is the gold standard for diagnosis, proper sampling and collecting methods are critical for improving diagnostic sensitivity. A number of thoracic imaging modalities with a characteristic feature have been recorded since the first occurrence of the disease in Wuhan, China in December 2019. The goal of this review paper is to provide insight into the diagnostic and prognostic features of chest X-ray, chest computed tomography, and lung ultrasonography in COVID-19 patients.
