| Research Abstract |
Nine CFS patients and ten healthy controls underwent 11C-(R)-PK11195 PET. 11C-(R)-PK11195 binds to translocator protein(TSPO) which glia cells express when inflammation begins. The BPND values of 11C- (R)-PK11195 in the cingulate cortex, hippocampus, amygdala, thalamus, midbrain, and pons was 45-199% higher in CFS/ME patients than in healthy controls. In CFS/ME patients, the BPND values of 11C-(R)-PK11195 in the amygdala, thalamus and midbrain positively correlated with cognitive impairment score, the BPND values in the cingulate cortex and thalamus positively correlated with pain score, and the BPND value in the hippocampus positively correlated with depression score.
