简要总结
The aim of the study was to assess the inflammatory status at the presumed peak of the inflammatory phase in non-critically ill patients requiring admission for COVID-19. Patients admitted with COVID-19 from March 27th to May 3rd, 2020 were prospectively enrolled. All patients had an initial chest CT-scan for diagnosis on admission and a second chest CT-scan for follow-up concomitant with a FDG PET/CT between day 6 and day 14 after the onset of symptoms.
详细描述
[18F]-2-fluoro-2-deoxy-D-glucose PET/CT (FDG PET/CT) is a sensitive and quantitative technic for detecting inflammatory process. Glucose uptake is correlated with increased anaerobic glycolysis seen in activated inflammatory cells such as monocytes, lymphocytes and granulocytes.
The aim of the study was to assess the inflammatory status at the presumed peak of the inflammatory phase in non-critically ill patients requiring admission for COVID-19.
Patients were included if COVID-19 was confirmed according to the WHO guidance (11) by a positive result of RT-PCR assay of nasal and pharyngeal swabs, if they were hospitalized during the time period from day 6 to day 14 of the onset of symptoms, and if their initial (on admission) chest CT-scan presented ground-glass opacities (GGO) or consolidation.
Group of 13 consecutive patients prospectively enrolled. All patients had an initial chest CT-scan for diagnosis on admission and a second chest CT-scan for follow-up concomitant with a FDG PET/CT between day 6 and day 14 after the onset of symptoms.
Based on the changes between the two chest CT, patients were classified as follows:

入选标准
- •Patients were included if COVID-19 was confirmed according to the WHO guidance (11) by a positive result of RT-PCR assay of nasal and pharyngeal swabs, if they were hospitalized during the time period from day 6 to day 14 of the onset of symptoms, and if their initial (on admission) chest CT-scan presented ground-glass opacities (GGO) or consolidation.
排除标准
- •Patients could not be included if their medical condition was unstable or precluded a safe transfer to the nuclear medicine department, if they were under mechanical ventilation (either non-invasive or invasive), if they were initially referred to the critical care unit, and in case of a pregnancy.
