Abstract

Coronavirus disease-2019 (COVID-19) is spreading throughout the world. Chest radiography and computed tomography play an important role in disease diagnosis, differential diagnosis, severity evaluation, prognosis prediction, therapeutic effects assessment and follow-up of patients with COVID-19. In this review, we summarize knowledge of COVID-19 pneumonia that may help improve the abilities of radiologists to diagnose and evaluate this highly infectious disease, which is essential for epidemic control and preventing new outbreaks in the short term.

Keywords: Coronavirus infection, Pneumonia, Radiology, Lung, Diagnosis

Core Tip: Viral nucleic acid testing is the gold standard of coronavirus disease-2019 (COVID-19), while chest radiography and computed tomography play an important role in disease diagnosis, differential diagnosis, severity evaluation, prognosis prediction, therapeutic effects assessment and follow-up of patients with COVID-19. Combining imaging manifestations with the epidemiology, etiology, pathology, pathogenesis, clinical manifestations, laboratory examinations and pathogen test is required for a radiologist to make an early diagnosis of COVID-19 pneumonia and monitor the course of disease. We herein elaborate on what radiologists need to know about COVID-19.
