Figure 4
Transverse views and quantitative and 3-D analyses of PET/CT images. Transverse views of PET/CT images: PET (left), CT (middle), and fused PET/CT (right) show intense 18F-FDG uptake in the CL-activated IBAT, but faint uptakes in the control and the cold-activated IBAT and scarce uptake in the propranolol-treated group (a). Quantitative analysis of PET/CT images for IBAT uptake in four studied groups (b). Data are mean ± SD; p < 0.001 as compared to the control (asterisk), cold-exposed (dagger), and propanolol-treated (double dagger) rats. 3-D analysis of PET (right) and PET/CT (left) images clearly showing interscapular, cervical, periaortic, and intercostal BATs (c).
