Fig. 3

Violin plot analysis comparing the TBR of parathyroid lesions in early-phase and delayed-phase images. The green group represents the early phase, whereas the orange represents the delayed phase. The red oval indicates the median value, while the size of the black box indicates the first and third quartile ranges. The rank-sum test of independent samples was used, and the TBR level in the delayed phase was significantly higher than in the early phase (P < 0.001). TBR is the tumor-to-background counts ratio
