This study was aimed to determine the effectiveness of two different lung ultrasonography (LUS) methods that can be used in the diagnosis of COVID-19 and to investigate its correlation with computed tomography (CT).
In this prospective, randomized and single blind study 60 patients with COVID-19 were included the study.Patients were randomized to either Group 12 zone LUS (n=30) or Group 14 zone LUS (n=30). The evaluation parameters were to determine the correlation between LUS and Thorax-CT scores. The secondary outcome measure examined the characteristic features of the findings in Thorax-CT and LUS.
The study was completed with a total of 59 patients .A moderate and high degree correlation was found between the CT and LUS scores calculated according to the total score in the 12-zone and 14-zone study groups. There was no statistically significant difference between the groups in terms of lesion types detected in patients on LUS and CT (p<0.05). Left lung lower lobe CT scores in the 14-zone study group were statistically significantly lower than the 12-zone group (p=0.019). Left lower lobe CT LUS score correlation was highly correlated in 14 regions examined group (p<0.001, r=0.954).
The results of our study indicated that the two different LUS examination methods performed on the different patients had similar findings in terms of diagnosis and their correlation with the results of the CT.
