- FIGURE 1.
Creation of region of interest (ROI) encircling radiopharmaceutical-outlined gallbladder. Ensure that gallbladder remains within ROI throughout post–Ensure Plus dynamic imaging.
- FIGURE 2.
Time–activity curve for gallbladder ejection fraction, determined from counts within gallbladder ROI throughout course of post–Ensure Plus dynamic imaging. Bkgd = background; EF = ejection fraction; T Max = time of maximum counts/s; T Min = time of minimum counts/s.
