CT Imaging and Differential Diagnosis of COVID-19

Abstract

Since the beginning of 2020, coronavirus disease 2019 (COVID-19) has spread throughout China. This study explains the findings from lung computed tomography images of some patients with COVID-19 treated in this medical institution and discusses the difference between COVID-19 and other lung diseases. RésuméDepuis le début de l'année 2020, la maladie à coronavirus 2019 (COVID-19) s'est répandue dans toute la Chine. Cetteétude analyse les résultats tirés des images de TDM pulmonaire de certains patients atteints de COVID-19 traités dans cetétablissement médical et examine la différence entre le COVID-19 et d'autres maladies pulmonaires.

Covid-19 med stille hypoksemi

“…Årsaken til lungesvikten er ikke klarlagt. Mattglassforandringer på CT tyder på interstitielle forandringer (3). Histopatologisk undersøkelse har avdekket diffus alveolaer skade (4).…”

Chest Imaging in Patients Hospitalized With COVID-19 Infection - A Case Series

“…Initial CXR showed patchy peripheral airspace opacities in the bilateral middle and lower lungs, concerning for multifocal infection (Fig 2A). The patient was discharged on doxycycline, with recommendations to self-quarantine for 14 CXR showed worsening of bilateral peripheral patchy pulmonary opacities (Fig 2 B). He was treated in the intensive care unit (ICU) with empiric antibiotics, hydroxychloroquine, and tocilizumab while intubated.…”

COVID-19: What Can We Learn From Stories From the Trenches?

“…However, the detection rate of COVID-19 by RT-PCR is low in early stages of disease and it takes 1 to 3 days to receive confirmation of a positive result. 2 Considering a highly contagious nature of COVID-19, delayed diagnosis may cause multiple additional cases of infection in general population and health-care providers in particular. Hence, the auxiliary test supporting the diagnosis is urgently needed.…”

“…A few reports have been published recently highlighting the role of chest computed tomography (CT) in diagnosis of COVID-19. [2][3][4] Chest CT demonstrates a high sensitivity in patients with COVID-19. The CT imaging findings in COVID-19 are similar to features of other viral pneumonias and familiar to imagers.…”

“…The CT imaging findings in COVID-19 are similar to features of other viral pneumonias and familiar to imagers. [2][3][4] The speed of acquisition of CT and timely reporting by radiologists will help our ED colleagues to make a diagnosis of COVID-19 within minutes, not hours or days. Nevertheless, this outbreak raises important clinical questions relevant to radiological community.…”
