Figure 1 Definition of postprandial contractility indices of the gallbladder. Postprandial gallbladder contractility was expressed by EF, which is determined as a percentage decrease in radioactivity, and ER, which is determined by EF/EP. Radioactivity was measured in three regions of interest in the gallbladder and EP was determined as the time of decrease on the time-activity curve. CPS: Counts per second.
