TSPO and COVID-19: For example, a preprint report of 2 such cases scanned with [18F]DPA-714 (or [18F]-labeled N,N-diethyl-2-[4-(2-fluoroethoxy)phenyl]-5,7-dimethylpyrazolo[1,5-a]pyrimidine-3-acetamide) PET finds regional elevations in an index of TSPO binding (TSPO BPND) greater than 70%, suggestive of larger magnitude elevations in TSPO level. Second, characterization of postacute COVID-19 symptoms is recent and ongoing; thus, some prominent symptoms observed in the present study, such as anhedonia and low motivation, were identified in the literature after the symptom measures for this study were chosen.
