Statistical Analysis
All statistical analysis were performed using R (version 4.2.0) and GraphPad (version 9.0) software. The descriptive data of SUVmean curve characteristics and quantification estimates were presented as mean (standard deviation, SD). Pearson’s correlation analysis was used to compare the relationship between the targeted areas, as well as assessing the agreement between the estimates generated by different approaches. P < 0.05 was considered statistically significant.
