Figure 2.

The numbers of visually identified fluorodeoxyglucose (vFDG)-positive muscle regions are correlated with the mean maximum standardised uptake value (SUVmax) in four extremities (A). Serum values of creatine kinase (CK) were higher in patients with more than two vFDG-positive muscle regions than in those with two or less regions (B). The number of vFDG-positive muscle regions correlated with the total histological scores (C). The mean SUVmax in four extremities correlated with the total histological scores (D). There were no differences in SUVmax in corresponding muscles between muscles with abnormal MRI signals and those without (E). In muscle regions examined by MRI, SUVmax in the corresponding muscles was higher in vFDG-positive muscles than in vFDG-negative ones (F).
