Diagnostic impact of bedside chest X-ray features of 2019 novel coronavirus in the routine admission at the emergency department: case series from Lombardy region

Abstract: To evaluate the diagnostic accuracy and the imaging features of routine admission chest X-ray in patients suspected for novel Coronavirus 2019 (SARS-CoV-2) infection. Method: We retrospectively evaluated clinical and X-ray features in all patients referred to the emergency department for suspected SARS-CoV-2 infection between March 1st and March 13th. A single radiologist with more than 15 years of experience in chest-imaging evaluated the presence and extent of alveolar opacities, reticulations, and/or pleura… Show more

“…To the best of our knowledge, there are only seven papers in the literature, excluding case reports and case series, evaluating the sensitivity of CXR in COVID-19 patients. Table 4 compares our results on sensitivity of CXR with those of the authors who performed similar estimates [7][8][9][10][11][12]. We found a sensitivity of CXR of 61.1% (95%CI 55-67%) in the identification of abnormalities in COVID-19 patients.…”

“…We found a sensitivity of CXR of 61.1% (95%CI 55-67%) in the identification of abnormalities in COVID-19 patients. Five studies, including ours, yield consistent 95%Confidence Intervals [7,[9][10][11]. There are two exceptions, at the two ends of the spectrum of values: the lower value reported by Weinstock et al [8], relative to patients admitted to urgent care centers, therefore likely to have a lower grade pathology, and the higher value reported by Schiaffano et al [12] for patients hospitalized in the Lombardy region, which might be due to the higher-grade pathology present in that region.…”

“…Chest x-ray could be useful to support diagnosis, especially during Sars-cov 2 pandemic: sensitivity values range from 57% to 89%. 20 However, Chest-x-ray can not detect spared lung areas: exclusive dorsal lung areas involvement can not be detected without latero-lateral projection, not usually performed in critical setting, requiring orthostatic posture. As observed by Marini, 4 COVID-19 pneumonia appears to include an important vascular insult that potentially mandates a different approach from that usually applied for ARDS.…”

“…Nesse sentido, a radiografia de tórax é um importante recurso na investigação diagnóstica da COVID-19 e deve ser considerada uma ferramenta útil especialmente em países onde o acesso à tomografia computadorizada está ausente. Além disso, ela pode minimizar o risco de infecção cruzada, pois a superfície da unidade portátil é facilmente higienizada, e pode, ainda mais cedo, reduzir a exposição global à dose de radiação (IPPOLITO et al, 2020;RODRIGUEZ-MORALES et al, 2020).…”
