Abstract:
Background In the past months, several lung ultrasonography (LUS) protocols have been proposed, mainly on previously
validated schemes independent of coronavirus disease 2019 (COVID-19).
Objectives The main purpose of this study was to determine the impact and accuracy of diferent LUS protocols proposed
in COVID-19.
Methods Patients were evaluated with a standard sequence of LUS scans in 72 intercostal spaces along 14 anatomic lines
in the chest. A scoring system of LUS fndings was reported and then analyzed separately according to each proposed LUS
protocol zones. This score was then correlated to a validated Pulmonary Infammation Index (PII) on chest Computed
Tomography (CT).
Results Thirty-two patients were enrolled. The most frequent pattern was ground-glass opacities in the chest X-ray (53.1%),
chest CT (59.1%) and subpleural or lobar consolidations (40.8%) in the posteroinferior areas (p <0.001) on LUS. The
Interclass Correlation Coefcient (ICC) was signifcantly correlated with almost every protocol analyzed except the 8-zone
(p=0.119) and the 10-zone protocol that only included one posterior point (p=0.052). The highest ICC was obtained with
a 12-zone protocol (ICC 0.500; p=0.027) and decreased as more points were included.
Conclusions In conclusion, our study results suggest that performing an ultrasound protocol with 12-zone scanning, including
the superior and inferior areas of the anterior, lateral and posterior regions of the chest was consistent with higher ICC and
higher degree of concordance with CT. We emphasize the need of a more standardization technique to further implement
and develop this imaging modality in COVID-19.
