[18F-FDG-PET/CT in SARS-CoV-2 infection and its sequelae]
Abstract
In recent months, much of the scientific efforts have focused on research on SARSCoV-2 infection and its consequences in humans. Still, many aspects remain unknown. It is known that the damage caused by SARS-CoV-2 is multifactorial and that its extension goes beyond lung inflammation and the acute phase, with the appearance of numerous complications and sequelae. To date, knowledge about the usefulness of 18F-FDG-PET/CT in the acute phase has been limited to the incidental detection of SARS-CoV-2 unsuspected pneumonia. Recent studies have been appearing collecting the findings of 18F-FDG- PET/CT in long COVID-19 or persistent COVID-19 state as well as the alterations caused after mass vaccination of the population in the metabolic studies. This work aims to review the existing literature focusing on these three issues and to briefly present our own preliminary experience.
Durante los últimos meses gran parte de los esfuerzos científicos se han centrado en la investigación sobre el SARS-CoV-2 y las consecuencias de su infección en humanos. Aun así, muchos aspectos siguen siendo desconocidos. Se sabe que la afectación por SARS-CoV-2 es multifactorial y que su extensión va más allá del daño pulmonar y del momento agudo, con aparición de numerosas complicaciones y secuelas. El conocimiento de la utilidad de la 18F-FDG-PET/TC en el momento agudo se ha limitado, hasta la fecha, a la detección incidental de afectación pulmonar por SARS-CoV-2. En los últimos meses han ido apareciendo trabajos que recogen los hallazgos de la 18F-FDG-PET/TC en el estado post-COVID, así como las alteraciones provocadas en la imagen metabólica tras la vacunación masiva de la población. Este trabajo pretende revisar la literatura existente sobre estas tres cuestiones y exponer de manera breve la experiencia preliminar propia.
