There is one clinical trial.
Ultrasound imaging of the lung (LUS) and associated tissues has demonstrated clinical utility in COVID-19 patients. The aim of the present study was to evaluate the possibilities of a portable pocket-sized ultrasound scanner in the evaluation of lung involvement in patients with COVID-19 pneumonia, in comparison with a high end ultrasound scanner. Statisical analysis will be performed with Stata for Windows V 16 (Stata corp, Texas College, TX). Power size estimation using Medcalc 19.3.1, (MedCalc Software Ltd, Ostenda, B) showed that hat 34 patients would be required for the comparison of the two methods using the Bland-Altman method assuming a mean difference in total score of 1±1, a false positive rate (α) of 0.05 and a false negative rate of 0.1 (β=0.9).
