Figures
- FIGURE 1.
Anterior and posterior 111In-DTPA images of abdomen are shown with examples of large rectangular regions of interest used to obtain total abdominal counts for calculation of geometric mean and decay-corrected total abdominal counts for all time points. There is small time point–to–time point variation in total abdominal counts; however, variation from mean is always less than 10% (Table 2).
- FIGURE 2.
Orientation and regions shown are same as in Figure 1, however, this figure shows example of patient in whom there is mild increase in total abdominal counts over course of 6 h of imaging.
- FIGURE 3.
Orientation and regions shown are same as in Figure 1, but in this case there is mild decrease in total abdominal counts over course of 6 h of imaging.
