COVID-19 findings in chest computed tomography

Abstract

OBJECTIVE:The aim of this study was to describe chest computed tomography image findings in patients with COVID-19. METHODS:The chest computed tomography scans of 453 hospitalized patients with confirmed COVID-19 were collected at two tertiary care Brazilian hospitals. Demographics and clinical data were extracted from the electronic record medical system. RESULTS:The main chest computed tomography findings were ground-glass opacities (92.5%), consolidation (79.2%), crazy-paving pattern (23.9%), parenchymal bands (50%), septal thickening (43.5%), and inverted halo sign (3.5%). Of the 453 hospitalized patients, 136 (30%) died. In this group, ground-glass opacities (94.1%), consolidation (89.7%), septal thickening (58.1%), crazy-paving pattern (52.2%), and parenchymal bands (39.7%) were the most common imaging findings. CONCLUSIONS:In a dynamic disease with a broad clinical spectrum such as COVID-19, radiologists can cooperate in a better patient management. On wisely indicated chest computed tomography scans, the fast identification of poor prognosis findings could advise patient management through hospital care facilities and clinical team decisions.

The Correlation between Biomarkers and Chest Computed Tomography Findings and the Severity of COVID-19 Patients

“…The majority of the hospitalized patients diagnosed with COVID-19 were men, with a rate of 53%. This result is in parallel with the studies in which 57% were male (Calvi et al, 2021) and 52% were male (Yurdaisik et al, 2021). The most common symptoms in COVID-19 patients are fever, cough, and shortness of breath, but some of them can have the disease asymptomatically .…”

“…Most hospitalized patients had more than 25% pulmonary involvement. Also, most patients who died due to it had more than 50% pulmonary involvement, indicating a worse prognosis depending on the size of the affected area (Calvi et al, 2021). Toussie et al reported that patients with ground-glass opacity detected in at least two pulmonary areas were more likely to need hospitalization.…”

“…The novel coronavirus disease , first identified as a pneumonia agent of unknown etiology in Hubei province in China in December 2019, was declared a pandemic by the World Health Organization (WHO) on March 11, 2019, and caused difficulties in the health system worldwide (Calvi et al, 2021). Adversely affecting millions of people worldwide, common symptoms of this disease are fever, myalgia, and respiratory and gastrointestinal system complaints (Wong et al, 2020).…”

Content analysis of NOC outcomes related to mechanical ventilation in people with COVID-19

“…The extent of lung commitment is a predictive factor of greater severity and mortality. The most common tomographic findings in severe cases consist of ground-glass opacity (92.5%), consolidation (79.2%), parenchymal bands (50%), septal thickening (43.5%), mosaic paving pattern (23.9%) and inverted halo sign (3.5%) ( 23 ) . Although less sensitive than chest CT, X-rays are useful in assessing pneumonia, pleural effusion or pulmonary edema, and the most common abnormalities are consolidation (28%) and ground-glass opacities (29%).…”

Covid-19 E Suas Sequelas Atreladas Às Alterações Neurológicas

“…( 28) En el presente estudio, la tomografía computarizada de tórax mostró una mayor sensibilidad que el ensayo, pero la sensibilidad fue solo del 73,3% entre los pacientes sintomáticos que dieron positivo para el SARS-CoV2 según RT-qPCR. (29) Bernheim y colaboradores, informó que la sensibilidad de la tomografía computarizada de tórax era baja (44%) en la fase aguda (0 a 2 días después del inicio) pero alta (91%) en la fase intermedia (3 a 5 días). La baja sensibilidad de la tomografía computarizada de tórax puede reflejar el corto período de tiempo entre el inicio de los síntomas y la hospitalización en los pacientes sintomáticos examinados en este estudio.…”
