On March 11, 2019, the WHO declared COVID-19 a pandemic disease. It is a
respiratory tropism SARS COV 2 infection. In the emergency of the pandemic, in
medical imaging, only computed tomography (CT) of the lungs was favored to
assess lung lesions. In addition, many cases of post-COVID-19 cognitive disorders have been reported. As the curve
dips and services restart correctly, other imaging techniques have been used to
better explore the disease. The objective of this presentation is to
illustrate the contribution of metabolic imaging in the exploration of post COVID-19
cognitive disorders and to discuss the pathophysiological mechanisms.
Hypometabolism brain lesions are objective signs of functional impairment whose
pathophysiological mechanism is not yet fully understood. Metabolic imaging
with PET-SCAN is a suitable tool for exploring these disorders, both for the
severity and extent of the lesions and for the topography of the brain damage.
