“…The lesions on CT being distributed peripherally in the current study can be interpreted in favor of COVID-19 pneumonia [13]. In addition, other findings such as ARDS or respiratory failure, shock, and multi-organ dysfunction may occur in the most severe form of COVID-19, the type defined as clinically critical disease [24].…”

“…Chest CT can show characteristic findings including ground-glass areas with or without signs of reticulation, called the crazy paving pattern, consolidative pulmonary opacities in advanced stages, and the reverse halo sign [1,11]. In addition, the often peripheral predominant distribution of lesions has been described as a typical finding in the literature [13]. Viral pneumonias such as influenza and organized pneumonia causing acute lung injury (e.g., due to drug toxicity or secondary to connective tissue diseases or idiopathic organizing pneumonia) can be considered in the differential diagnosis of these findings [4,14].…”

“…However, a systematic review on this subject suggested that chest CT findings were very similar between pediatric and adult patients [25]. In terms of distribution, lesions are more common in the lower lobes and spread to other regions within days the progression of the disease [9,26,27]. In an early study that included 866 respiratory samples from 213 patients, the sensitivity of RT-PCR was found to vary between 42.9% and 88.9%, depending on the stage of the disease and the type of clinical sample examined [28].…”

“…During the early period of the pandemic, chest radiography (chest-X ray, CXR) was preferred as the primary imaging modality for clinical monitoring and treatment adjustment in adult patients with COVID-19 [7]. Chest CT is another important diagnostic method when evaluated together with clinical findings in the diagnosis of COVID-19 pneumonia and management of adult patients, and it was extensively used in the early period of the pandemic [7][8][9]. cases [13].…”

The findings of chest radiography (chest-X ray, CXR) have not been confirmed in evaluating the prognosis of pediatric patients with coronavirus disease 2019 . In this study, we aimed to analyze the prognostic value of the CXR infiltration severity scoring system at the initial presentation of pediatric patients with COVID-19. Hospitalization and long-term data were recorded. The admission CXR data of 310 patients aged 1 month to 18 years who presented to our hospital between March 2020 and January 2021 with the diagnosis of COVID-19 confirmed by the real-time reverse transcription-polymerase chain reaction (RT-PCR) test were included in the study. The CXR images of each patient were evaluated in terms of the presence, type and localization of lesions by a radiologist, and the lung severity scores were calculated. Clinical and laboratory variables were also noted. The relationship between clinical parameters, imaging findings and patient outcomes was statistically evaluated. The median age was 9.1±5.2 years, and 59.7% of the patients (185/310) were male. Abnormal CXR findings were found in 6.5% (20/310) of the patients. CT was performed in 25 patients (8.1%), of whom 20 had normal CT findings. The time between the onset of complaints and admission to the hospital was 2.8±1.1 days in patients with abnormal CXR findings 3.0±1.4 days in those with normal findings, indicating no statistically significant difference (p=0.58). The duration of hospital stay of the patients with abnormal and normal CXR findings was 9.75±2.6 vs 9.47±2.0 days, respectively, and the difference was not statistically significant (p=0.78). None of the patients required intubation, and all had a good prognosis. For patients aged 1 month-18 years presenting to the emergency department with COVID-19, CXR presents as a useful modality in the diagnosis of associated pneumonia and it has similar results compared with CT. Our results revealed that CXR could be used in symptomatic children to assess COVID-19 pneumonia. We suggest that CT should be used for the further analysis of possible pathologic findings or complications on CXR, if clinically indicated.

“…Coronavirus disease 2019 (COVID-19) that emerged as a pneumonia outbreak in Wuhan, China, in the last month of 2019 and was found to be caused by the newly identified severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has been declared a global public health emergency by the World Health Organization (WHO) considering its pandemic potential ( 1 , 2 , 3 ). Although the reverse transcription polymerase chain reaction (RT-PCR) test is the gold standard for the diagnosis of COVID-19, in cases of COVID-19 presenting with pneumonia, the computed tomography (CT) of the chest provides valuable information about diagnosis, disease severity, and prognosis ( 4 , 5 , 6 , 7 , 8 ). In addition, chest CT plays an important role in the diagnosis process and determining the prognosis, especially in patients with respiratory failure and those requiring hospitalization.…”

Purpose : To evaluate the prognostic value of the vertebral bone mineral density (BMD) on chest computed tomography (CT) in COVID-19 patients. Methods : The chest CT of hospitalized patients with COVID-19 pneumonia were evaluated for Pneumonia Severity Score (PSS) as the ratio of the volume of involved lung parenchyma to the total lung volume. In addition, BMD was manually measured from the vertebral corpus using axial CT images. The relationships of clinical variables, PSS and vertebral BMD with patient outcomes, namely mortality, intensive care unit (ICU) admission and mechanical ventilation were investigated. Lower BMD was defined as ≤100 HU. Results : The study included 209 patients (118 males, 56.4%). As a result of the univariate analysis, the rates of mortality, ICU admission and mechanical ventilation were 17.2% (n=36), 24.8% (n=52), and 20.6% (n=43), respectively, and they were significantly higher among the patients with lower BMD (38.1 vs. 13.0%, p <0.001; 33.4 vs. 21.2%, p =0.002; and 38.1 vs. 8.2%, p <0.001, respectively). In the mortality group, PSS was significantly higher (median, 9 vs. 5; p <0.001) and vertebral BMD was significantly lower (median, 83 vs. 139; p <0.001). Severe clinical incidence was significantly higher in patients with lower BMD compared to those with higher BMD (39.7 vs 24.7% and p =0.028). There was a significant correlation between clinical classification and lower BMD (r=0.152 and p =0.028). The multivariate analysis revealed vertebral BMD [odds ratio (OR), 1.028; 95% CI, 1.011-1.045, p =0.001) and lower BMD (OR, 4.682; 95% CI, 1.784-12.287, p =0.002) as significant independent predictors of mortality. Conclusion : Vertebral BMD is a strong independent predictor of mortality that is reproducible and can be easily evaluated on the chest CT images of COVID-19 patients.
