Furthermore, the DVR of [11C]-(R)-PK11195 in FM patients demonstrated decreased neuroinflammation in the medulla (p < 0.005), left superior temporal gyrus (p < 0.005), and left amygdala (p = 0.020) compared with healthy controls. Conclusions To the authors' knowledge, this report is the...

Reference tissue kinetics extraction from [11C]-(R)-PK11195 scans on the high resolution research tomograph (HRRT)The count rate performance of two commercial PET tomographs, the CTI HR+ (BGO) and Accel (LSO), is compared from simulations of blood flow studies. Data were derived from in ...
However, [ 11 C]-( R )-PK11195 may not possess the required sensitivity to visualize mild neuroinflammation. In this study, we evaluated the PET tracers [ 11 C]-DPA-713 and [ 18 F]-DPA-714 as agents for imaging of activated microglia in a rat model of herpes encephalitis.Rats were ...
