Current Status of Etiology, Epidemiology, Clinical Manifestations and Imagings for COVID-19

Coronavirus disease 2019 (COVID-19) is a transmissible respiratory disease that was initially reported in Wuhan, China in December 2019. With the alarming levels of COVID-19 spread worldwide, the World Health Organization characterized COVID-19 as a pandemic. Over the past several months, chest CT has played a vital role in early identification, disease severity assessment, and dynamic disease course monitoring of COVID-19. The published data has enriched our knowledge on the etiology, epidemiology, clinical manifestations, and pathologic findings of COVID-19. Additionally, as the imaging spectrum of the disease continues to be defined, extrapulmonary infections or other complications will require further attention. This review aims to provide an updated framework and essential knowledge with which radiologists can better understand COVID-19.

Infection Control and Management Strategy for COVID-19 in the Radiology Department: Focusing on Experiences from China

Coronavirus disease 2019 (COVID-19) is a new infectious disease rapidly spreading around the world, raising global public health concerns. Radiological examinations play a crucial role in the early diagnosis and follow-up of COVID-19. Cross infection among patients and radiographers can occur in radiology departments due to the close and frequent contact of radiographers with confirmed or potentially infected patients in a relatively confined room during radiological workflow. This article outlines our experience in the emergency management procedure and infection control of the radiology department during the COVID-19 outbreak.

Chest CT--The gatekeeper to COVID-19 / 医学研究生学报

In December 2019, an outbreak of pneumonia associated with a novel coronavirus (SARS-CoV-2）emerged in Wuhan and spread rapidly throughout China and beyond. As the first-line imaging modality, thin-section chest CT is easy to perform, fast, available. Combined with epidemiological history and clinical manifestations, positive CT findings can highly suggest the early diagnosis of Coronavirus Disease 2019 (COVID-19) with high sensitivity, so that timely isolation and intervention can be implemented for suspected and confirmed patients. CT can also help assess the disease severity, and surveil disease course, so as to guide clinical decision and provide prognostic information. This paper outlines the CT imaging features of COVID-19 and highlights the value of chest CT in its diagnosis and treatment with the reference to the official documents and latest researches.
