Abstract
Coronavirus disease 2019 (COVID-19) was reported for the first time in the Chinese province of Wuhan and then rapidly spread worldwide, to be declared a pandemic on March 11, 2020. It is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) .This virus can be transmitted via droplets and progress to severe acute respiratory distress syndrome, sepsis, and septic shock, which may require intensive care especially in patients with comorbidities.
Since the beginning of the COVID-19 outbreak, many diagnostic approaches were attempted to early and reliably identify patients suspected of infection and to stratify them according to disease severity. In this context, chest CT played a key role because of its high sensitivity.
Lung ultrasound (LUS) has emerged as a potential imaging technique with low costs and widespread availability. Although chest CT is considered gold
standard to assess lung involvement, with specificity
superior even to that of the nasopharyngeal swab for diagnosis, LUS examination can be a valid alternative to
CT scan, with certain advantages, for pregnant women in particular. Ultrasound can be performed directly at the bed-side by a single operator, reducing the risk of spreading the disease among health professionals. It is a radiation-free and repeatable exam as well.
The aim of this study was to determine the correlation between LUS and CT findings in SARS-CoV-2 infection, to assess the performance of LUS to classify lung abnormalities and to evaluate the possibility of using this technique to provide a quantitative assessment of pulmonary involvement in COVID-19 patients.
The plan was to do lung ultrasound (LUS) to assess the lung involvement for thirty patients proven to be PCR +ve for COVID – 19 in the Radiology department at Ain Shams University Hospitals and National Hepatology and tropical medicine research institute after full history, clinical examination and laboratory investigations CT chest done. CT results were compared with LUS findings and scoring system.
This study showed that in a sample of patients with PCR proven COVID-19, Patients with respiratory symptoms or comorbidities tended to have more changes on LUS and more extensive disease on CT. There was a relationship between the abnormalities detected by the imaging modalities; In addition, LUS score is associated with severity as assessed by chest CT scan and clinical features
