The role of lung ultrasonography in evaluation of COVID-19 pneumonia

After a few months it emerged in Wuhan (China), Coronavirus Disease 2019 (COVID-19) caused by novel coronavirus (2019-nCoV) was declared as pandemic the World Health Organization (WHO). Diagnosis of disease is mainly based on real time polymerase chain reaction (PCR) test nasopharyngeal swab. However, due to excess numbers false-negative PCR results, chest computed tomography (CT) commonly used supplementary modality. CT has some disadvantages. Firstly, normal scan does not exclude diagnosis COVID-19 pneumonia. Additionally, radiation exposure and weak diagnostic value are other challenges. When infection limited upper respiratory system or performed early stage, results may be obtained scan. Recently lung ultrasonography (LUS) easy-to-use, cost-effective radiation-free tool diagnosis, management follow-up In this narrative review, our aim clarify utility LUS pneumonia with its advantages We also aimed guide clinicians use practical tool.
