The metabolism of RMTG in the cognitive continuum. a Plot showing RMTG SUVR of NC2, SCD2, aMCI, ADD, and DLB; b plot showing RMTG SUVR of NC, SCD, aMCI, ADD, and DLB. The SUVR between SCD2 and NC2 (p = 0.034) as well as SCD and NC (p = 0.010) both had significant differences; there were no differences between the ADD and DLB groups (p = 0.227 in a, p = 0.162 in b) but there were significant differences for the remaining combinations (p < 0.001 both in a and b; not marked in Fig. 2). The above p values were all subjected to Bonferroni correction. Abbreviations: RMTG, right middle temporal gyrus; SUVR, standardized uptake value ratio; NC, normal control; SCD, subjective cognitive decline; aMCI, amnestic mild cognitive impairment; ADD, AD-dementia; DLB, dementia with Lewy body
