Heart/organ uptake ratios. The %ID/cm3 of heart was divided by that of liver, stomach, and intestine to calculate the uptake ratio of heart/liver (A), heart/stomach (B) and heart/intestine ratios (C) at different time points post-injection of the tracer. Data were presented as mean ± SD (n = 6). * P < 0.05, ** P < 0.001, *** P < 0.0001 versus the data points at 3 min.
