Abstract
<i>Background</i>: COVID-19, which is predominantly transmitted by contact between people, turns out to be a public health emergency of international concern and it lacks specificity in both clinical manifestations and laboratory tests. It mainly causes inflammatory lesions in the lungs and can also cause injury to other major organs. Imaging methods have an important role in the diagnosis and evaluation of treatment strategies for COVID-19. Computed tomography plays an important role in the diagnosis and evaluation of the severity in compliment with the RT-PCR test. Comprehensive analysis of the patient's epidemiological history, clinical symptoms, laboratory test and imaging manifestations are necessary in order to early detection, early isolation, and early management. <i>Objective</i>: The purpose of this review was to summarize the radiographic, CT patterns and ultrasonographic features of COVID-19 pneumonia in order to help health professionals for reliable basis for early diagnosis and management of COVID-19. <i>Methods</i>: The literature search for this document was carried out comprehensively by accessing PubMed, Google scholar, Web-of-Science and other data bases. In addition helpful documents were added. <i>Result and conclusion</i>: The most common CT features of COVID-19 are peripherally distributed ground glass opacities, crazy paving pattern and patchy consolidation. Lung ultrasound has a key role in the clinical management of patients with COVID-19 associated lung injury.

Coronavirus Disease 2019 (COVID-19), which is mainly transmitted by contact between people, turns out to be a public health emergency of international concern
The type and size of computed tomography (CT) abnormalities are related to disease severity
B lines are visualized in all their possible forms and COVID-19 pneumonia can be described as storm of clusters of B lines giving the appearance of shining white lung [38]
Summary
Coronavirus Disease 2019 (COVID-19), which is mainly transmitted by contact between people, turns out to be a public health emergency of international concern. The COVID-19 pandemic brings to a huge burden on healthcare services, in patients with comorbidities [1]. It lacks specificity in both clinical manifestations and laboratory tests. The diagnosis of COVID-19 depends on reverse transcription-polymerase chain reaction (RT-PCR) or gene sequencing of throat swab, sputum or lower respiratory tract secretion [4, 5]. These methods are time-consuming, high false negative rate and do not allow assessing the disease severity. I tried summarize the radiographic, CT patterns and ultrasonographic features of COVID-19 using available evidence pneumonia in order to help health professionals for reliable basis for early diagnosis and management of COVID-19
