“…This finding is in agreement with a study carried out in an emergency department [ 25 ]. Another study compared both methods in a hospital setting but did not evaluate statistical significance [ 33 ]. Despite the relatively small sample size used here, this research included a larger patient group than other studies that evaluated the use of lung ultrasound for COVID-19 diagnosis [ 23 , 24 , 31 ].…”

Background: The COVID-19 pandemic rapidly strained healthcare systems worldwide. The reference standard for diagnosis is a positive reverse transcription polymerase chain reaction (RT-PCR) test, but results are not immediate and sensibility is variable. Aim: To evaluate the diagnostic accuracy of lung ultrasound compared to chest X-ray for COVID-19 pneumonia. Design and Setting: A retrospective analysis of symptomatic patients admitted into one primary care centre in Spain between March and September 2020. Method: Patients’ chest X-rays and lung ultrasounds were categorized as normal or pathologic. RT-PCR confirmed COVID-19 infection. Pathologic lung ultrasound images were further categorized as showing either local or diffuse interstitial disease. McNemar and Fisher tests were used to compare diagnostic accuracy. Results: Most of the 212 patients presented fever at admission, either as a standalone symptom (37.74% of patients) or together with others (72.17% of patients). The positive predictive value of the lung ultrasound was 90% for the diffuse interstitial pattern and 46.92% for local pattern. The lung ultrasound had a significantly higher sensitivity (82.75%) (p < 0.001), but lower specificity (71%) than the chest X-ray (54.02% and 86%, respectively) (p = 0.008) for identifying interstitial lung disease. Moreover, sensitivity of the lung ultrasound for severe interstitial disease was 100%, and was significantly higher than the chest X-ray (58.33%) (p = 0.002). Conclusion: The lung ultrasound is more accurate than the chest X-ray for identifying patients with COVID-19 pneumonia and it is especially useful for those presenting diffuse interstitial disease.

“…Other studies compared LUS and CXR in COVID-19, demonstrating a higher sensitivity of LUS [22,23]. These studies used a binary classification of the interpretation of LUS based on the presence of generic artifactual abnormalities that, in our opinion, does not adapt to the real practice.…”

Descriptive analysis of a comparison between lung ultrasound and chest radiography in patients suspected of COVID-19

Background Lung ultrasound (LUS) and chest radiography (CXR) are the most used chest imaging tools in the early diagnosis of COVID-19 associated pneumonia. However, the relationship between LUS and CXR is not clearly defined. The aim of our study was to describe the comparison between LUS interpretation and CXR readings in the first approach to patients suspected of COVID-19. Methods In the time of the first COVID-19 pandemic surge, we prospectively evaluated adult patients presenting to an emergency department complaining of symptoms raising suspicion of COVID-19. Patients were studied by LUS and only those performing also CXR were analyzed. All the patients performed viral reverse transcriptase-polymerase chain reaction (RT-PCR). LUS studies were classified in 4 categories of probabilities, based on the presence of typical or alternative signs of COVID-19-associated interstitial pneumonia. Accordingly, the CXR readings were retrospectively adapted by 2 experts in 4 categories following the standard language that describes the computed tomography (CT) findings. Patients were divided in two groups, based on the agreement of the LUS and CXR categories. Results were also compared to RT-PCR and, when available, to CT studies. Results We analyzed 139 cases (55 women, mean age 59.1 ± 15.5 years old). The LUS vs CXR results disagreed in 60 (43.2%) cases. RT-PCR was positive in 88 (63.3%) cases. In 45 cases, a CT scan was also performed and only 4 disagreed with LUS interpretation versus 24 in the comparison between CT and CXR. In 18 cases, LUS detected signs of COVID-19 pneumonia (high and intermediate probabilities) while CXR reading was negative; in 14 of these cases, a CT scan or a RT-PCR-positive result confirmed the LUS interpretation. In 6 cases, LUS detected signs of alternative diagnoses to COVID-19 pneumonia while CXR was negative; in 4 of these cases, CT scan confirmed atypical findings. Conclusion Our study demonstrated a strong disagreement between LUS interpretation and CXR reading in the early approach to patients suspected of COVID-19. Comparison with CT studies and RT-PCR results seems to confirm the superiority of LUS over a second retrospective reading of CXR.

“…The most common lung ultrasound (LUS) findings in screened studies and their relative prevalence were irregular pleural lines (27.9 to 89% in patients), pleural thickening (6.5 to 86%), separate "distinct or scattered" B-lines (16.6 to 88%), confluent "coalescent" B-lines with or without "white lung" (12 to 78.6%), pulmonary consolidations (31.1 to 77%), sub-pleural consolidations (8.06 to 73%) and pleural effusions (3.8% to 56%) [74][75][76][77][78][79][80][81][82] [Table 2] . Variability in prevalence of LUS findings is likely related to heterogeneity in the severity of the disease, as well as the timing of LUS in the course of the disease.…”

“…These data suggest a promising role for LUS as an alternative to CT scan for screening patients with suspicion of COVID-19, as well as assessing the severity of the disease. Shumilov et al compared LUS findings to chest X ray (CXR) in 18 symptomatic COVID-19 patients and found LUS was useful in detecting interstitial syndrome compared with CXR (94% "B-lines" vs. 61% "hazy increased opacity"; p<0.02) as well as detecting lung consolidations effectively (77% for LUS vs. 38.8% for CXR; p<0.02) [77]. Similar findings were described by Pare JR et al, wherein LUS was more sensitive than CXR (88.9% vs 51.9%, respectively) for the association of pulmonary findings of COVID-19 (p = 0.013).…”

The manifestations of COVID-19 as outlined by echocardiography, lung ultrasound (LUS) and cardiac magnetic resonance (CMR) imaging are yet to be fully described. We conducted a systematic review of the current literature and included studies that described cardiovascular manifestations of COVID-19 using echocardiography, LUS and CMR. We queried PubMed, EMBASE and Web of Science for relevant articles. Original studies and case series were included. This review describes the most common abnormalities encountered on echocardiography, LUS and CMR in patients infected with COVID-19.
