  • * Statistically significant based on Bonferroni adjustment (P < 0.016).

  • Mean ± SD is reported for SUV in liver, blood pool, and myocardium. For lesion SUVmax, SUVmax ratio, and SUV gradient, median, with range in parentheses, is reported for better correlation with values in Table 3. Change (%) indicates value change in percentage from GeminiTF to DigitalTF.
