Correlation between the metabolic rate K
and Standard Uptake Value and retention index, respectively. (A) K
and (in SUV units) and (B) K
and retention index (in percent). is the tissue uptake at t = 55 min. Dashed lines represent the least squares straight line fits to the data. The inset graph in (A) additionally provides the correlation between and , which helps to explain the group of data points above the regression line with SUV > 8 (see the ‘Discussion’ section).
